MIKE READ PITS™ 2 – C269TIP – Part 2 – Low Profile De Luxe SlipIt.

Leave a comment

Digression: Did you think we were born in peaceful times?

In Western Europe today, amid increasing concerns over violence and insecurity, carrying a fixed blade — something I’ve done for decades with a short fixed blade — or even a locking folder can easily be misinterpreted.

And every single day, in the fall of 2025, the European newspapers report yet another knife attack or crime.

Knife attacks in the United Kingdom have shown a persistent and worrying upward trend in recent years. National data indicate that police recorded just over 53,000 knife‑enabled offences in the latest annual cycle, with assaults and robberies accounting for a substantial portion. While knife-related homicides represent a small percentage of overall offences, the absolute numbers remain high, with young people disproportionately affected. Offences involving the possession of bladed weapons have also risen, highlighting broader issues of accessibility and carrying habits in urban areas. Compared to a decade ago, knife-related violence has increased significantly.

(From a locking folder to slipjoint folder…. Sign of the times ?)

Most knife crimes in the UK use everyday knives like kitchen knives, because they’re cheap and easy to access. But a significant minority of attacks involve more “exotic” or dangerous blades: like machetes !

In Germany, some state-level police offices estimated more than 21,000 knife attacks in 2022, which corresponds to about 60 knife attacks per day nationally.

In France, knife attacks also remain a major concern, with more than ten thousand recorded assaults involving bladed weapons in the most recent year across areas policed by the national force alone. This figure corresponds to roughly a few dozen attacks per day and does not include all regions or the gendarmerie’s jurisdiction. Schools in the Paris region reported over a hundred knife-related incidents within a year, highlighting a sharp increase in youth involvement and the normalization of carrying knives. Broader national indicators show rising attempted homicides and a high proportion of armed robberies committed with knives, underscoring the central role of bladed weapons in everyday violence.
French law places certain knives (e.g., automatic opening, butterfly/balisong knives, fixed-blades over a certain size, double-edged blades) into stricter categories (Category D weapons) when carried without legitimate reason. Folding pocket-knives of everyday use (e.g., classic French models) are more tolerated — they may be treated as tools rather than weapons if not used aggressively or carried without justification.

CountryEstimated Knife-Crime / Knife-Attack Rate (per 100,000)
England & Wales (UK)~89 / 100,000 (using ~55,008 knife-enabled offences and a population of ~61.8 M)
France~15 / 100,000 (based on ~10,397 reported “knife attacks” and a population of ~68.6 M)
Germany~10.7 / 100,000 (using ~8,951 knife-attack figure from 2023 data)



In the UK, the rules are straightforward: a non-locking knife with a blade under 3 inches.
But now it seems that one-hand-operated folders are no longer welcome;
For the record, one-hand operation is actually safer: not only for opening, but also for closing the knife. A closed folder is a safe folder, and being able to switch your tool into “safe mode” quickly is a genuine advantage.

In France, things are far murkier — everything hinges on intention and context of use. It’s almost a Minority Report situation.

Ironically, in the country of Opinel and Laguiole, we’re now backpedaling because of sheer stupidity. And I’m not blaming the criminals who use knives to hurt people — that’s obvious. I’m blaming the people who carry a knife for self‑defense.
After a search from the Police in front of an high school:
“Why do you bring this knife to school ?”
“To defend myself !”
A knife is not a self‑defense tool — it’s a catalyst for problems.
Awareness, on the other hand, is a self‑defense tool, and that’s something you really need to keep sharp.
Even something as simple as wearing AirPods can compromise your ability to stay safe, cutting you off from your surroundings.

Unless you’re a gangster settling scores with your own kin, a knife will never be your bodyguard — not even with training.
In fact, it can make things worse, especially if you think you’re “trained in knife fighting.” A knife as a weapon is a killer’s tool, meant for ambush and combat, not for duels.

(The only blade that might actually “help” you — for example in an attempted‑rape situation where you are physically overwhelmed, dominated, and restrained — is also the one that will almost certainly land you in even more trouble afterward. And if you ever reached that true last‑ditch moment, your best hope would ironically be a short serrated edge rather than a razor edge; under an adrenaline surge, an aggressor won’t even register a clean cut. The Spyderco Manbug Wharncliffe SpyderEdge comes to mind.
But even then, you would need the mindset to become the aggressor just to survive — and you must be prepared to defend your actions in court afterward.)

I remember reading about an elderly man who was being harassed by a gang of young men. In the confrontation, he slashed the hand of one of his aggressors with his Swiss Army Knife — and in the end, he was the one standing before the judges.
“To claim self‑defense, sir, there must be proportionality between the attack and the response.”

“It’s also a mindset.
I’ve carried a knife since I was 9 and have never had the inclination to cut or stab someone.
It’s all about how you have been raised.”
Des Horn

So let’s remain ladies and gentlemen, and let’s be low profile in our EDC choices.
The knives we carry and appreciate are not pocket bodyguards — they’re tools we genuinely enjoy using for simple, everyday tasks.

Enter the Alien/PITS2 and the whole generation of modern slipjoints.

Carrying a knife in today’s civilian world means opening parcels, prepping food, cooking, doing small repairs — being a handyman or -woman, or at least trying to be. I’ve written before about the modern slipjoints we now have access to: knives that benefit from three decades of “tactical” evolution. They offer deep-carry clips, true one-hand opening and closing, and high-performance steels refined for modern cutlery.

All of that is perfectly embodied in Spyderco’s SlipIt line.



So why would you choose a Mike Read folder? Is it better than a UKPK or an Urban?
Nope. The SlipIt flagship UKPK, for example, also has a thin edge, and you can even dress it up with titanium scales if you feel like it. Its mechanism is also stiffer, with a two-stage closing “safety” that makes the blade feel more controlled on the way down.

So why choose the PITS2?
It ultimately comes down to taste — your willingness to spend a bit more, your appreciation for the mechanism, the maker behind it, and of course a love for titanium and M398.

So what does the Alien/PITS2 truly bring in the long run?

In my case, I was genuinely surprised by how this “hard-to-open-one-handed” knife has grown on me.
That stiffness actually makes it reassuring to carry — you know the blade won’t pop open by accident. Especially when you carry it in the back right pocket.

First: it slides in and out of the pocket effortlessly.
That deep-carry clip is a real asset. It reminds me of the C181GTIP Lil’ Lionspy — also made in Maniago — but this one is even better than a wire clip: smooth, secure, and gentle on pockets.

Even though it’s light, the PITS2 feels dense and substantial in the hand. If you love titanium, you immediately recognise that warm, almost organic sensation it gives in the palm. Chris Reeve was the first to offer that pure‑titanium tactile experience, and the PITS2 carries that same aura.

Then your thumb finds the hole. It’s stiffer than most Spydercos I know, but that final click when fully opened is immensely satisfying. Forget about using your ring finger — it’s your thumb or nothing.

The hole is sharp enough to allow a “Spyder‑Drop,” though it occurs in two deliberate steps rather than one smooth motion.

Another major advantage: the PITS2 cannot pinch your fingers during opening or closing — a problem that the PITS1 sometimes had.

And, as I mentioned in the quick first‑look, that relatively tall blade comes with very thin geometry. This is the first Spyderco edge in a very long time—aside from my Chaparrals—that didn’t need to be convexed. I usually “de‑shoulder” everything to my taste and to my standard test: the plastic bottle butt.

This is where the PITS2 truly shines: pure cutting performance.
So far, it has never disappointed me. At first, I thought its more “gentle” blade tip wouldn’t be pointy enough for my tastes—especially since I’m used to the UKPK, Yojimbo 2 or the Microjimbo—but the PITS2’s tip is razor‑keen. It finds its way into soft or dense materials with nothing more than a light, controlled pass.

Actually, butter knives do not need to be sharp. 😉
The PITS2’s thin edge can slip effortlessly through delicate materials—like slicing a layered birthday cake without crushing it. And it can zip through cherry tomatoes, which is always a great test of geometry and edge aggressiveness. Tomato skin resists, tomato flesh is fragile; a good blade needs to pierce the first without mangling the second.

Well, well, well… go figure: tomatoes can be tricky — and a perfect opportunity to put your favorite edge to the test.
But honestly, what more could you ask for from a good EDC, superb slicing ability. A sharp knife is a safe knife.


M398 in that matter continues to surprise me. It reacts to leather like… K390 ! Amazing steel !
I’ve already used M398 on the Roadie XL and the Metropolitan, and it proved far more forgiving than I expected. I initially thought it would be brittle — especially after snapping about half a millimeter off the tip of my Roadie XL — but in everyday use it has shown itself to be an excellent alloy that also responds beautifully to stropping.


After some real use, I still haven’t managed to chip or even noticeably dull the PITS2’s thin edge. What’s remarkable is that it’s still as razor-sharp as it was right out of the box.


I also love how easy it is to check, clean, and oil the PITS2.
I can appreciate how skeletonized hidden liners have added lightness and strength to folding knives, but they also tend to become little nests for rust. For that reason, I really appreciate it when liners are DLC‑coated — and even better when they’re made of titanium.

Regarding the PITS2’s titanium handle, the absence of hotspots and the beautifully beveled edges make it a real pleasure to hold.

The cutout for the mechanism isn’t beveled, so you can feel its slightly sharper edge. I’ve also noticed that the two handle slabs are symmetrical, while the cutouts around the pivot are not identical.


Low profile usually comes with a deep‑carry clip or no clip at all… but the PITS2 clip is really shiny, so it still catches the eye. I know, because I’ve checked my reflection in a mirror and eventually had to unclip it and drop it deep into my pocket before passing through security recently.
Low profile wise: a tip if you are ever checked, do not open your knife with one hand, use both.

In those days of increasing knife crime and genuily believe that your EDC’s shape needs to be sheeple‑friendly.
If I pull out my fully serrated Native Chief Salt, anyone around will instantly assume that this long, pointy, toothy, shiny blade is straight out of Jack the Ripper’s toolkit.


The PITS2, with its rounded profile and non‑threatening blade shape, is a perfect example of a legal and friendly high tech EDC that won’t raise any eyebrows if used in public.
It’s actually even less threatening than a UKPK.

ll in all, the PITS2 delivers on its promises.
Incredible thin edge. Enjoyable mechanism. Low profile. Easy to clean.

It’s a friendly, high‑tech luxury tool that can be brought to the table to slice a sausage, yet also serves as a reliable outdoor companion capable of carving a walking stick. I’m loving the Alien in these times of shifting paradigms.

So let the weary land be rested and the killing season over
Let the shadows stretch forever in the light of burnished silver
For I fear the age of consequence and I wish that it was over
Bring me the snowfall, bring me the cold wind, bring me the wiener…

(My Nano has been heavily resharpened into a convex edge, while my PITS2 comes with its thin, perfectly even factory edge.)

MIKE READ PITS™ 2 – C269TIP – The Legal Alien

Leave a comment

Disclaimer: This knife has been provided through Spyderco’s Ambassador Program, upon my own request. Thank you to the Spyderpeople for letting me review it.

This is a first look, first glimpse review — my very first impressions!

Mike Read’s custom Alien (£400,00 Elmax Blade) was presented to the world in November 2023, and it is now produced by Spyderco through Maniago, Italy under the name PITS 2 in 2025 for around €300,00.
So this is an English design, produced by a Colorado-based company, and manufactured in Italy — you can’t get more international than that.

To respect the King’s Law in the UK, you need to carry a non-locking knife with a blade under 3 inches, and also have a good reason to carry it on your person. The PITS 2 respects those rules and looks far less threatening than the original PITS 1.

This isn’t my first Mike Read design — I reviewed his PITS 1 back in 2018 and loved it. That knife was his very intention of creating a solid workhorse with no lock. Two years ago, a sprint run in M390 appeared.
Now comes the PITS 2, in M398, and to me, this is a much better design. Here’s why.

“Pie In The Sky” (not pig!) was Mike Read’s nom de guerre on the British forums. His specialty as a knifemaker is crafting non-locking knives: state-of-the-art tools with titanium handles and obsessive attention to detail.
The PITS 1 was a looker — but the PITS 2? It’s eye candy.

Here’s a video from The Crafter Carry about the Alien:

Compared to the more angular tip of the custom Alien, I find the PITS 2 blade shape more graceful, with a nicer drop to the point.

The custom Alien used a titanium clip, whereas the production PITS 2 wears a steel one — but I actually prefer Spyderco’s version here.

What really makes it stand out is the handle mechanism:

“A truly unique non-locking mechanism that consists of two integral spring arms machined into the handle scales. The forward end of these arms, which supports the blade pivot, flexes as the blade is opened to provide pressure for its notched-joint mechanism to bear against the stop pin.”

That’s clever: just two integral spring arms machined into the handle that hold tension on the blade pivot. The absence of a traditional backspring makes for an open-handle design — easier to rinse under the tap and keep clean. Exactly what you want in a workhorse.
(Let’s be clear: If you anticipate heavy-duty work (construction, field outdoors, survival uses) where a strong locking mechanism is required, then this may not be the optimal choice — you’d trade some robustness for style and finesse.)

The blade is made of Böhler-Uddeholm M398 particle metallurgy stainless steel — a steel in the same class as CPM S90V. It holds an edge forever, though it’s not the toughest, and you’ll need diamonds to sharpen it.
I once broke the tip of my Roadie XL after a fall on tiles, but when used as intended, M398 is delightful. I’ve worked my Roadie XL and Metropolitan hard, and M398 has never failed me. This steel would be perfect also for hunters which need long edge holding when skinning.

Mechanically, this is the first Spyderco I’ve handled that’s harder to open than to close. The blade retention in the closed position is quite strong, while closing is much softer than most slipjoints. With wet hands, I even find it tricky to open — I have to “Spyder-drop” it by holding it by the hole!

At least, if a Police officer asks to see it, you must open it with two hands — another good point, as it’s clearly a gentleman’s knife, not a weapon. Also, while the PITS 1 looked somewhat like a skinner, the PITS 2’s drop point blade is much less aggressive-looking.

Inside the “cockpit,” there’s now a choil and a gentle hump, allowing a secure grip near the blade — something the PITS 1 lacked with a more aggressive quillon or guard for the index finger. So even with its softer closing action, it’s not a real issue. Still, when whittling hardwood, beware: that tall blade can snap shut faster than a UKPK or an Urban, both of which have stronger backsprings. Always use the choil!

The tall, thin blade arrives razor sharp out of the box. Geometry is spot-on for push cuts, and like the Slipjoint, Manly Wasp, Chaparral, or UKPK, performance is excellent. Let’s call that: “Perf In The Sky.”
This will be a great travelling companion and even a hunter best friend.

Totally UK legal and of the highest quality imaginable, the PITS 2 is not a cheap knife — in fact, it’s pricier than the Chaparral Slipjoint — but it has that “Sebenza-like”feel of a high-quality titanium folder. A gem of a knife, and one of the rare non threatening slipjoints truly designed to be a hard worker.

As rare as pies in the sky!

Spyderco Chaparral® SLIPIT™ Birdeye Maple C152NLWDP – The Lucky Charm.

1 Comment

The Chaparral series is quite unique in Spyderco’s catalog. Originally designed to showcase different handle materials on the same platform, it has evolved into a performance-driven tool for one simple reason: the blade stock is exceptionally thin.
That thinness means it cuts deep with minimal effort.

It is even thinner than the UKPK which is the thinnest of the SlipIt Family.
(“SLIPIT®” is Spyderco’s trademark name for non-locking folding knives.
These knives stay open through spring tension rather than a mechanical lock.)

2mm for the Chap and 2,5 for the UKPK.


I’ve owned the original carbon fiber version, and earlier this year I reviewed the Lightweight serrated model — still one of the most efficient “matter separators” you can carry in your pocket.
Now, thanks to the Spyderco Ambassador Program, I’ve had the great opportunity to test the Slipjoint Chaparral.

It’s worth pointing out that the Chaparral is far from an entry-level model. It’s the premium, Taiwanese-built sibling in the SlipIt family — and at about twice the price of most SlipIt knives, it clearly plays in a higher class.

And this is an eye candy:

You can notice that Spyderco even includes a transparent protector over the clip area to prevent the handle from the clip during transport.


The knife arrived sealed in a plastic bag, likely to protect the wooden handles from changes in humidity.
Made in Taichung, Taiwan, and shipped to Golden, Colorado, this precaution makes perfect sense — Golden’s dry climate has been known to affect wood scales before (as seen with their Bushcraft fixed blade).
The handles themselves are beautiful. Carrying a piece of wood in your pocket almost feels like carrying a good luck charm.


This is my first Spyderco folder with wooden scales, and I must say — it has real charm.


The knife comes with Spyderco’s standard wire clip, but I have swapped it out for the shorter clip used on the MicroJimbo, Lil’ Native, or Dragonfly — it’s more discreet and I wanted to do it before leaving any mark on the wood.

Here pictured with the Metropolitan and with the microclip mounted on.
A downside of the wire clip is that it can create a “hotspot”, or point of discomfort, when applying significant pressure.
That’s why I prefer that shorter clip cannibalized from another folder — it helps avoid this issue. When doing extended wood prep or cutting in the field, where downward force is applied, ergonomics really matter.

BTW the Metropolitan pictured above costs about half the price of the Chaparral, and while both fall into the same blade-length category, the Met’s blade is roughly 33% thicker. The Metropolitan’s M398 blade is impressive when it comes to edge retention, but the CTS-XHP used on the Chaparral has proven to be a reliable, all-terrain stainless steel that performs beautifully on that exceptionally thin blade stock. An M398 blade at just 2 mm thick would certainly be too brittle for practical use.

Here is the Chap pictured with the MicroJimbo, the UKPK, the Serrated Chap, the Wasp and the Roadie XL.

Now, about the mechanics:
The Chaparral SLIPIT specifically replaces the usual Chaparral’s back-lock with this “notch-joint” spring system. The Chaparral backlock is also unique in the Spyderco catalog as it get an hidden pin for zero vertical play .
Most Spyderco slipjoints close in two stages — first, disengaging the spring tension, then a mid-stop for safety.
Not the Chaparral. Once you disengage the spring, the blade flows smoothly all the way to the closed position.
(Compare that to the Manly Wasp (pictured in orange) or Comrade, which both have four distinct steps!)
That said, disengaging the blade on the Chaparral requires a bit of effort — which is actually a good thing, especially for whittling. Feeling a blade start to close while it’s wedged in wood is never pleasant.
I’ve had that experience with the beautiful COBOL, and it’s not something I’d want to repeat.
Compared to other SlipIt models, the Chaparral is not in the same range of spring tension. I was initially afraid the action might feel too soft.
It is not soft but noticeably less hard than my UKPK, Urban, Squeak or Metropolitan. My strongest being my Heinnie G10 Urban.

All in all, the Chaparral is a very capable tool — not just a pretty face.
While its aesthetics are undeniably strong (especially with those bird’s-eye maple scales), some users have raised concerns about the stability and durability of the wood in moist or wet environments.
Naturally, a wooden handle requires a bit of care — you don’t want to let it soak in the sink. (Buy a UKPK Salt instead !)
Wood isn’t G10 or FRN; its warmth and character come at a small cost in terms of maintenance and environmental sensitivity.
If you need something very rugged (wet/humid environments, rough carry), it might not be the best choice or you might pick a version with more durable scales.

And again, that blade stock is so super thin which makes it an incredible slicer. Opinel class ! You need to experience it to believe it.
That’s the case for all Chaparral anyway, nothing new about that.



The fit and finish is near perfect. Notice how the spine and handle are gently bevelled as always with Taichung’s !
This is little folder for users who prioritize slicing performance, sharpness, and elegance, the Chaparral SLIPIT is just appropriate for EDC/“gentleman, lady” use.
The non-locking SLIPIT mechanism is suited for jurisdictions (including Europe/UK) where locking blades may be restricted — that adds to its appeal.  If you want also a knife that carries lightly, looks premium, and doesn’t feel like a bulky tactical folder, this hits that niche. But you may want to treat its maple scales carefully and avoid heavy moisture.
I will rinse my Chap under the tap but immediately wipe it dry, this is as simple as that. I will see if wood will change on the long run and it will surely add some character. No worry.
The non-locking SLIPIT mechanism may not feel as secure as a lock-back, and the “no half-stop” means the feel is really different that other SlipIt designed by Sal Glesser.
Anyway any Chaparral will teach you a lesson on the importance of grind and thin geometry but this one will keep it legal in many countries.



If you’re seeking a precise, elegant everyday-carry folder with top-tier steel, superb slicing geometry, refined looks and minimal pocket presence — the Chaparral SLIPIT delivers strongly.
Oh boy does it slice, hell yes.
And it brings luck.

SPYDERCO SQUEAK Part IV – The Micro SlipIt as the only travel knife.

Leave a comment

Choosing a travel folder is easy for me — I own quite a few knives of various lengths dedicated to that purpose.
Traveling from France to the UK, however, means avoiding any locking blade and any edge longer than 3 inches (76 mm).

Models like the UKPK, Metro, Urban, Chaparral Slipjoint, The Roadie, the Manly Wasp, or even the Couteaux des Sorgues or any small Swiss Army Knife, would all fit the bill.

For the record the non locking mechanism of the SlipIts is reviewed in this review here.

But this time, I’ve decided to take the Squeak designed by Sal Glesser. The Titanium/Elmax Sprint Run Jewel. Easy to pocket, One Hand opening are my choice. Usuaully I use a UKPK from Heinie for my UK trips.
This time, it will be the Squeak Deluxe. This micro-folder has been a constant companion in my pocket since 2017, and it’s perfectly watch-pocket friendly — but as my only knife for a road trip? That’s the real question.

I don’t know about you, but my uses for a knife when traveling abroad are many — from cutting labels to sharing a piece of cake.

The first thing I ask from a blade is that it stays very, very low-profile.
A deep-carry clip is mandatory in that regard. However, the Squeak’s stock clip isn’t exactly discreet, so I swapped it for a MicroJimbo clip — the same one used on the Lil’ Native — which is noticeably shorter.

Frankly, this shorter clip should come standard on all SlipIt models from the factory!

I often use my EDC knives right on the plate. Eating with a sharp blade is non-negotiable — and most of the time, my wife ends up borrowing mine, so it goes back and forth throughout the meal.

Of course, ceramic plates aren’t exactly a razor edge’s best friends. They can sharpen a blade in spots, but mostly they’ll dull it fast.

For food prep or eating on a plate, my favorite blade shape is the Wharncliffe, since only the tip makes contact with the hard ceramic surface. The MicroJimbo would have been perfect for that — if only it weren’t a locking knife. Honestly, I’d love to see a Wharncliffe SlipIt someday!

For now, the Squeak brings a bit of belly and that razor-sharp Elmax edge. It truly shines with pizza — that perfect mix of soft top and hard crust demands a blade that cuts deep and steady.

I didn’t bring any sharpening stone to touch up the edge, but I found that mostly the tip was the part coming into contact with the ceramic.
With longer blades, I usually tilt the knife slightly to avoid any 90° cuts against the plate. But with the Squeak, I just went at my pizza like a hungry wolf.

The result? A bit of dulling — maybe 1 mm toward the tip — but nothing I actually noticed during the trip.
I sometimes straighten a rolled edge on a mug’s rim or a sink edge, but not this time. I didn’t bother. Elmax isn’t brittle, so there was no real concern anyway.

The tip needs to stay razor sharp, since I also use it to open plastic bags, while I use the edge near the pivot for cutting labels. Despite the dulling, I couldn’t feel any loss of performance on plastic.

Using a short blade naturally means a bit more sawing motion, or sometimes two slashes for one cut — but with the Squeak, that was no issue at all.

Its biggest challenge might have been scones, but with those, I just think twice and cut once!
Even slicing a lemon for tea worked perfectly — I simply rolled the fruit on the board while cutting through it.

All those mundane tasks only proved how essential the Squeak was as our sole cutting tool during our five-day road trip.
It handled every meal — cutting bread for toast, slicing soda bread leaves — and never once did I feel underknived.
The Squeak performed flawlessly in every task, and above all, it was an absolute pleasure to carry and use.

So, does size matter?
In this case, the Squeak has clearly proven itself as both a great travel companion and a perfect EDC for countries that are cautious about knife laws.

Spyderco’s SLIPIT™ Family – Which one should you choose—and for what purpose?

3 Comments

The SLIPIT™, is a group of American-designed folding knives developed by Spyderco. Originating from the UK Penknife (UKPK) project
— the first folding knife to combine their one-hand-opening Trademark Round Hole™, clip carry, and a non-locking mechanism — and drawing inspiration from the Caly series, the group comprises the UKPK, Metropolitan, Urban, and Squeak models. All were designed by Sal Glesser.




The Blue Brother of my Slipit family is the UK Penknife (UKPK) Blue G10 CPM SPY 27 version AKA “The great slicer” or “The Golden Child” as it is made in Colorado when the others are made in Italy.
My UKPK is the G10-handled version in CPM SPY27 steel. It features the thinnest blade (2.5 mm vs 3mm for the other members of the SlipIt family) and offers the best slicing performance, with a cutting edge measuring 75 mm.
You can notice its this G10 version got 4 screws on the handle. (When Spyderco site is only showing 3 screws for their UKPK G10 SPY27 model)
Edit: I got an answer from Golden about that:
“The photo of the G10 model you see online is a photoshopped version of the lightweight model, which only has 3 screws. The 4 screw version is standard for the g10 variant.”
The FRN UKPK got 3 screws and a short spring/backspacer. Perhaps easier to rinse and clean. Its Salt version even exist in yellow with CPM Magnacut and in green with LC200N and also with serrated edge.

On mine, its thin CPM SPY27 blade is particularly well-suited to maintenance by leather stropping, and this model is unique in the group for employing a fork spring, likely necessitated by the longer stainless steel backspacer. Thanks to its blade steel, the UKPK also provides the greatest lateral strength of the series.

Its versatility makes it suitable as a travel knife, steak knife, whittling tool, office companion, or even a light kitchen knife.
You can even change for another style of clip if you want a toolish look.
The UKPK won’t let you down FRN or G10 version. They are great travel non threatening folders.

TECHNICAL SPECIFICATIONS
Overall Length: 6.89in 175mm
Closed Length: 3.95in 100mm
Blade Thickness: .098in 2.5mm
Blade Length: 2.95in 75mm
Edge Length: 2.57in 65mm
Handle Material: G-10
Origin: United States
Steel: CPM® SPY27®
Knife Weight: 2.2oz 63g

The Black Brother of the Slipit family is the Metropolitan, a tad shorter than the UKPK but often described in my book as having “an everlasting edge.” This model is notable as the only Slipit presented here with an FRN (fiberglass-reinforced nylon) handle. FRN is great and solid and the Metro got a full spring/back spacer.

Its key strength lies in the choice of blade steel: Böhler M398, known for delivering extremely long-lasting edge retention at a comparatively very accessible price point. Despite its 3 mm blade stock, the Metropolitan remains an excellent slicer. While M398 offers less lateral strength than CPM SPY27, it excels in edge holding, making this model particularly well-suited as a folding skinner or for heavy-duty tasks such as breaking down cardboard.

TECHNICAL SPECIFICATIONS
Overall Length: 6.31in 160mm
Closed Length: 3.73in 94mm
Blade Thickness: .118in 3mm
Blade Length: 2.68in 68mm
Edge Length: 2.43in 62mm
Handle Material: FRN
Origin: Italy
Steel: M398
Knife Weight: 1.6oz 45g

The Red Brother of the Slipit family is the Urban, my Low Profile London Traveller, produced as an exclusive edition for Heinnie Haynes. This model was acquired at approximately twice the cost of the Metropolitan, owing to its premium blade steel: CPM S90V, a high-performance alloy offering edge retention on par with Böhler M398. Now the FRN Urban is released with M398 too which makes my previous expensive Heinnie S90V Urban quest totally obsolete.

Released prior to the availability of the Metropolitan and the M398 Urban, this knife also features a G10 handle with a distinctive finish. Its compact dimensions allow it to be carried discreetly, such as in the watch pocket of denim trousers. In this collection, the Red Brother is primarily employed as a travel knife for use in London. I have it equipped with the short MicroJimbo clip for the lowest profile possible.

The Silver Brother – The Tweetanium !
The Squeak is truly a jewel within the SlipIt family. Despite its compact size, it never leaves me feeling “under-knived” when carried in a watch pocket.
I once owned a Squeak Deluxe Sprint Run with a titanium handle and Elmax steel blade, which I eventually passed on to JD. Thanks to Guillaume, I was able to acquire another example, new in box.

JD first acquired the original Squeak SC154PBK and used it extensively, praising its thin cutting edge, dependable Böhler N690Co steel, ergonomic handle, wire clip, and reliable one-handed usability.

Later came the titanium sprint-run version, which felt even sharper at the edge, requiring less effort when cutting. Its rounded titanium scales were warm to the touch, slipped smoothly into the pocket, and offered a more refined feel than the FRN model. The stiffer titanium construction also produced a stronger spring, giving the knife a crisper “walk and talk.” While one-hand opening was slightly more demanding, both versions remained capable of the classic “Spydie drop.”
The titanium scales are smooth under the thumb and provide superb ergonomics in a three-finger grip. Construction is minimalist, relying on only two body screws plus one for the deep-carry clip.

This is a three fingers grip when the Urban is still a four finger grip.

This rare titanium variant stands out as a refined upgrade over the standard Squeak—an elegant evolution of an already excellent design.
I love Elmax steel since my Lionspy. I remember beating the crap out of it and it was really forgiving: no chipping and great sharpness. It is tough for a stainless steel.

Its short blade is full-flat-ground, exceptionally thin at the edge, and employs a slipjoint-style “notched-joint” mechanism: the spring holds the blade open during use and offers resistance when closing.

It slice through a Coke bottle butt with its factory edge ! Not many models from the Spyderco line can do that right out of the box.
In practice, performance is outstanding. The small blade slices cleanly through materials such as plastic, wood, ropes and even after extended use—up to a year on my first Elmax Squeak—it remains razor-sharp with only minimal stropping required. Elmax, a rare style among Spyderco knives, is that good !

The Spyder hole and blade spine are the also the sharpest of the family. It could be used to strike some ferro rod.

Compact yet versatile, the “mini micro” knife proves remarkably capable for everyday tasks: cutting meat at the table (where the blade’s belly is especially effective), opening tags, breaking down plastic, and more. It also maintains a discreet, non-threatening presence in public and restaurant settings. It makes a great money clip too.

Le Choix des Armes

  • Blue UKPK – the versatile slicer.
  • Black Metropolitan – the non locking hunter’s companion.
  • Red Urban – the low-profile city dweller.
  • Silver Squeak – three fingers power house.

Each model is reliable, discreet, and delivers outstanding cutting performance thanks to their blade geometry. They shine on the plate and impress with pure slicing ability on the hardest materials (my pastic bottle tests…). Thanks to their relatively strong non locking mechanisms, they also handle whittling tasks—yes, even the Squeak is surprisingly pleasant and powerful against any piece of wood.
And don’t forget, now their slip-joint strength is impeccable. Also each knife comes with a choil, keeping your fingers safe from unwanted blade closure.
Really, when it comes to staying open, Sal Glesser’s four slip-joint designs outclass his excellent Roadie XL—and put Anderson’s COBOL to shame.
Sharp, firm, secure, and reassuring—no surprises when handling these slipjoint knives which are proof that size doesn’t define performance. 😉

Mama Caly can be proud of her slipIt offsprings !

Six months with the Golden Child – Spyderco -C94GCBL- UK PENKNIFE™ COBALT BLUE G-10 CPM® SPY27® – The Part 2

3 Comments

I have had the chance to buy that UKPK in G10 for 100 euros in January 2025.
Since, it has been my “go to the city” favorite folder.

Sometimes replaced by the Roadie XL for a lower profile or Dredd my Urban in S90V made in Maniago and exclusive to Heinie in the UK.


The UKPK is remarkably versatile, proving itself even in woodworking. Its strong, reliable mechanism keeps it ready for anything — all while remaining fully within legal limits. Stripping vines, carving rods, scraping, cutting — it handles everything with ease. The spring “lock” never falters, and the finger choil adds an extra layer of passive safety, even if it’s rarely needed.

Its thin yet strong CPM SPY27 blade is a true joy to use on wood. In this domain, the UKPK stands out as one of Spyderco’s best hidden gems across all categories made in Golden. And if I ever had to defend myself against an animal, I believe it would perform every bit as well as the legendary Calypso (all the story here).

The tip has seen plenty of use, and all I can say is that Spyderco’s in-house SPY27 steel is extremely forgiving. You can push it hard with no damage to the edge. I’ve compared it with many of my favorite wood-cutting knives — including some specialized for woodworking — and it performs impressively in the same league.

One way I now measure the value of a pocket knife is by the pleasure I get from using it. The UKPK easily ranks among the top on my list. Strong, thin, and precise, it excels as a true “matter separator,” handling everything from everyday tasks to more demanding jobs like scraping paint.

There’s also a distinct joy in keeping the edge razor-sharp, and SPY27 has become my new favorite for that. Achieving a razor edge is a breeze. Being in the AEL-B class, it’s even easier to work on than Magnacut and is extremely leather-stropping friendly. After just a quick session on leather, SPY27 regained that legendary crisp edge — and it’s such a pleasure to use!

Hairs are flying and the convexed home made edge is shining like a mirror.
This is really part of the joy to use leather strops on a steel.

So it is a joy just to strop it again and again just to maintain this razor edge.

Then for forced push cuts, the geometry of the UKPK is just a killer.
It goes deep like a thin Opinel blade can go.

To keep the knife sharp, I’ve mostly relied on leather stropping, with occasional touch-ups on white ceramic, even after cutting cardboard, plastic, acidic food, and hard wood. The UKPK in SPY27 is a winner, offering a significant boost in edge retention and versatility. Maintaining its vorpal edge is even easier and more enjoyable than with the excellent Magnacut or LC200N versions.

It’s no wonder this steel has earned such a special place in my heart.

And I was not able to get any chipping or edge bending in six months.
It gives an hint about the high quality of the inhouse heat treatment on that inhouse steel.

Used in the plate, the SPY27’s core refused to be damaged:
no pitting, no rust, no stain. No damage on the plate ceramic too.
It a gourmet companion and a wonderful carnivorous friend.

In the kitchen, geometry-wise, the UKPK can compete with the best — for example, the Patrick Bonetta Kitchen Warrior. The G10 version is also a visual delight. I never felt “under-knifed” with my Urban, but the UKPK could easily be my one and only Spyderco. A three-inch, legal, high-performance sharp blade is a must-have for EDC, and such knives are surprisingly rare.

This is 100% Sal Glesser design. This Golden-made gem is the all-terrain pocket knife my grandfather would have dreamed of!
Hence its name The Golden Child. 😉

For an alternative you can now get The Metropolitan. Its little brother.

Spyderco -C94GCBL- UK PENKNIFE™ COBALT BLUE G-10 CPM® SPY27® – The Blue Djinn Who Loved Leather.

Leave a comment

This is not the first UKPK I have reviewed in this blog. I was a very early adopter of this Sal Glesser’s approach of the modern slipjoint all made in Golden Colorado.
Some of my favorite are the Salt Versions in FRN: the Green LC200N and the Yellow CPM Magnacut. I even think, the serrated version of the Magnacut version could be an amazing legal travelling knife.

But they are FRN versions. I like FRN but I do love G10. Better, I’m a sucker for sanded G-10. Hence my love for the Heinnie Urban and its non-slip peel-ply texture.
At first glance the satin-finished CPM SPY27 blade and signature cobalt blue peel-plytextured G-10 handle scales are juste gorgeous. Here are the full specs on Spyderco’s pages.

Like the Heinnie the skip joint got a strong mechanism. It is really a pleasure to feel this resistance which was totally absent from the very first drop point UKPK a decade ago. (Picture from Mr Blonde, Spydercollector site)

So far, I cannot imagine my self opening it with a flick like I was able to do on the LC200N FRN version. The Spring here on this G10 version is much stronger.

Let’s do some size comparaison. The UKPK is one of the long Slipit in Spyderco’s collection. It is almost a slipjoint Caly, even longer than a Chaparral. So you really don’t feel “underknifed” when you carry it in your pocket as your only EDC. It is also really handy and practical as a kitchen knife. The best thing is that this design keeps its blade length legal in most countries.

For cooking I often use a Native Chief.

The long leaf shaped blade is a must in the kitchen almost idea. It is pointy enough and its is enough for vegetables. Most of the works done in the kitchen like peeling potatoes, cutting oinions, you name it, was always done with a short full flat ground knife like a “Nogent Couteau d’Office”.

Something about the G-10 version is the spring/back spacer closing the handle of the knife when the FRN got an open handle easier to rinse.
But it is much more gorgeous and with a stronger spring for sure !

It also gives a little more heft to the knife. 48 grams for the FRN and 63 grams for the G10 version -> 31,25% heavier to be precise, almost a third ! But I do really love my heavy butt knives since my Schrade Sharpfinger.

Now this is my first CPM-SPY27 knife. Spy27 is a alloy recipe created in house with Crucible exclusively for Spyderco. It is a CPM ! So this is a premium super steel compared to VG10 or N690… In short it is a American Powder Metallurgy version of the Japanese VG10.

In Sal Glesser words:
“We offer many steels for several reasons;
1) We are Steel Junky’s (even Edge Junky’s) and we like to experience the different flavors and we try to do that.
2) We believe that many of our customers are also Steel Junky’s (even Edge Junky’s) and they too get to experience and play with and “taste” as you say, the many options.

I wanted a USA made “tweaked” version of Gingami 1 by Hitachi and after some effort with Carpenter, we have a powdered USA made steel called CTS-BD1N Which is a refinement of Gingami 1. I wanted a USA made “tweaked” version of Takefu’s VG-10 and now we have a powdered “tweaked” SPY27.“

Carbone1.25%
Chrome14%
Molybdène2%
Vanadium2%
Niobium1%
Azote0.1%
Cobalt1.5%
Manganèse0.5%
Silicium0.5%



There is a very nice analysis in Knifesteelnerd and discussion here: https://forum.spyderco.com/viewtopic.php?t=94182

“However, it should be noted that the SPY 27 Larrin used for testing was not heat treated by Spyderco. Some minor differences between Larrin’s heat treatment and Spyderco’s heat treatment can probably be expected. That being said, Larrin is the best source of consistent, objective data and metallurgical interpretation for steel comparisons.” To quote Karl_H in
https://forum.spyderco.com/viewtopic.php?t=87383

“SPY-27 will hold the fine edge longer… Its all about the stability of the fine edge, not the total wear resistance until fully dull. In this regard, SPY-27 can do what other stainless steels cant.” to quote Submicron in the same thread.

I am aware that Cobalt’s dust can be an health issue. Of course Rex 45 and Maxamet (10% of cobalt, 1,5% for SPY27) are the heavy weight steel in their tool steel category but the Spy27 (like VG-10), like all cobalt alloys needs to be carefully cleaned after a sharpening process.
(Cobalt may cause an asthma-like allergy. Future exposure can cause asthma attacks with shortness of breath, wheezing, cough, and/or chest tightness. * Cobalt may affect the heart, thyroid, liver and kidneys. * Repeated exposure to Cobalt dust can cause scarring of the lungs (fibrosis) even if no symptoms are noticed. According to https://nj.gov/health/eoh/rtkweb/documents/fs/0520.pdf)


Let say SPY-27 is in the same club as the S35VN steels in terms of performance and it especially loves fine ceramic and leather stropping. It gets easily a very crispy edge like VG10 or BD1N . ( Steel which are “leather super friendly” are also LC200N, 52100, VG10, AEB-L… )
This is a must and a real pleasure for me as I keep my knives sharp mostly with leather. A touch up and it makes flying hairs from my arm again.
And it seems true so far. I have not deshouldered the edge yet and intend to use it with the factory edge for some times but leather made it hair popping sharp. (Once deshouldered it is a straight razor with excellent edge retention… much better than S30V).
To quote Sal:
“SPY27 for some reason, seems to be punching above its weight.”

No crossroads, this Blue Djinn loves leather like the Bill Moran FB01 in VG10 loved it.

No need to use diamonds unless you want to reprofile the blade or round the shoulder then don’t forget to rinse the blade and to clean any dust.
But talking about dangerous dust, I have sanded the scales to preserve my pockets. Never breath that dust !!! Do it under water or wear a mask.
I got a neighbor who has been working around that kind of heavy dust and now he is breathing with two tubes in his nostrils. So be careful with your health.
This Blue G10 got a very nice texture under the thumb like some denim, textil like. It is really pleasant, almost like some Micarta found on the QSP Penguin.

So when you sand G10, just go outside in the wind or work under water. You don’t want to breath G10 dust made of fiberglass and epoxy.
Just rinse it under the tap to have it back to normal.
Once tuned at your hand, G10 is a very very nice material.

As you can notice the scales are even thicket than the blade and the blade is perfectly centered.

There is the famous middle/half stop when closing or opening the knife. It works like a safety measure. This knife is harder to close than to open.

The UKPK is a very ergonomic knife. It feels like it melt in the hand. It is so confortable for heavy cuts. Because this blade can work hard with zero play.

The “pistol grip” is common in many Sal Glesser design like the Endura or the Military. It is much more pronounced on the Massad Ayoob.

No hotspots for me a very safe handle, really, this lil slipjoint is screaming to be used hard.

It is even confortable edge up.

With the Roadie XL. Another great Slipit with a very low profile, almost like a pen in your shirt pocket.

And the mighty Chaparral serrated. Two of Sal’s best designs. Two wolves in sheep disguise thanks to their thin solid blades.

I have decided to de-shoulder the edge for a gentle convex result in the middle of the belly.

My old leather with some polish compound is ready again to smooth the edge to razor level.

Because I want a better touch on the leather, I usually keep the normal edge at the point to keep material there and near the ricasso as I use this portion for special shores like removing the aluminium cap on bottles.

The Coke Bottle Butt test is passed with flying colors. As you can notice the plastic is 3mm thick. Not a single scratch on the blade.

So what do we got so far ?
A master piece of knife design by monsieur Sal Glesser with a strong construction and state of the art in-house alloy serving a thin blade and an ergonomic handle.
My advice: try to grab one before they disappear, it seems that G10 version is not here to last and it is really a sapphire: a true blue jewel !

C127GPRD SPYDERCO URBAN HEINNIE® EDITION – The S90 Urban UK Legal Wonder.

5 Comments

Spyderco Urban, Squeak and UKPK family is one of the most addictive slipjoint proposition in the modern world. I have already written about them in this blog. The UKPK Salt is simply one of the best modern folder available nowadays. The Squeak is totally sheeple friendly and of course the Urban made for the city and to be carry everywhere but on the airlines.

Spyderco’s description:
“This Exclusive version of the Spyderco Urban™ was manufactured specifically for Heinnie Haynes (heinnie.com) and is available only through their sales channels.  Originally introduced in 2009 and later discontinued, the Urban remains a cult classic among devoted fans of Spyderco’s non-locking, one-hand-opening, clip-carried SLIPIT™ knives. This distinctive expression of it showcases a leaf-shaped blade crafted from premium CPM® S90V® particle metallurgy stainless steel. The PlainEdge™ blade is full-flat ground for exceptional edge geometry and is proudly laser engraved with the Heinnie Haynes logo.Not to be outdone, the handle of this knife features distinctive red G-10 scales with a non-slip peel-ply texture. They complement the jimping (textured grooves) on the blade’s thumb ramp and index-finger choil to ensure a positive grip and outstanding control during use. A reversible deep-pocket wire clip provides a choice of left or right-side tip-up carry, making every aspect of the design completely ambidextrous.”

This Red One is my third Urban. The first one was in K390, the second one was in AEBL and named Cappucino. All of them has been pushed out of my pocket because of the greatness of the UKPK Salt in LC200N.
Anyway they all have been great companion during my UK travels as they are totally legal: non locking under 3 inches blade (76mm)…
Eventually I have been looking for a G10 version with a full stainless steel back spacer and I have found the Heinnie Haynes exclusive version available on their site. It is not a cheap knife be aware of that but it oozes quality on paper and in the hand.

First thing first, this Urban got a CPM S90 V blade, the same found on the Proficient Bushcraft knife. S90V was known before as CPM420V and it is still one of Sal Glesser favorite steel ever to be produced by Crucible.

S90V is known for its incredible edge retention and in the last 25 years of using it, I can tell you this one can be a bear to resharpen. Diamonds are its best friends and even then it needs a lot of white ceramic time and stropping… Compared to non stainless super steel like Maxamet it can be really tedious to get really sharp. But one it is sharp, its working edge seems to stay forever on.
This is exactly the opposite of my previous experience with Cappucino my AEB-L Urban. This one was strong and a breeze to keep razor but it was back to butter knife level quick when used on abrasive matters like cardboard for example.
S90V eats brown cardboard for breakfast and it stays sharp for very long but is it tedious to put it back to a crispy razor edge.
That’s great when you need long lasting working knife on a trip when you have not planned to bring a sharpening stone for example and Sal trusts enough S90V to put that very alloy on all his own special Sprint Runs with CF Handle. I have never been disappointed by S90V and even on fixed blades or on the Manny folders it has always been a game changer in term of long lasting sharpness and is even better than CPM100V in my book.
S90V is also very stainless. Unless you want to use your knife in the ocean, it can handle some hard work in the forest without to be cleaned immediately.
It has been found that this S90V Urban got a little thinner blade 0.23 cm against 0.29 cm… The blade is also a little shorter than previous Urban bot nothing I have noticed in terms of utility.

This Urban has been made in Italy and in my own experience Maniago craftmanship has never been a bad surprise. Your mileage may vary but this is mine. I have been happy with my Spytalians !

G10 is not a current material on Urbans as FRN is everywhere and, better, the texture of this G10 is even more unique. I was first thinking to turned this knife into a pebble but, naah ! It is great as it is.
I have just adjust the feel by sanding it but all in all this is great high quality made handle and again kuddos to Maniago.
All Heinnie Haynes exclusive got that red treatement on the handle, this is their signature. And a G10 version got a longer steel backspace on the handle closing it.

Now about the action, this Urban has been the most hard to close of all my splipjoints ! It is really a positive point. I can still open it with quick movement of my wrist but the closing ask for some force which is really rare (even in Spyderco production, the first UKPK were chewing gums to quote Guillaume, Spyderco Fan Club moderator).
Strong spring, and no lock make it a great candidate for carrying a legal folder nowadays.

Now about geometry, Maniago desserves another kuddos ! As you can see on the picture above, I was able to split a bottle butt in a single pass with the factory edge. This is also rare ! Even my lovely Hellboy needed some thinning before to reach that level. This is thin geometry right out of the box !!
The short blade drop point makes it a great whittler and Spyderco knows how to make little big knife. The hump and the choil are transmitting your force’s cuts directly to the blade, sparing the handle, its axis and its mechanism. This is clever and Sal has been inspired by San Francisco Gambler’s knives. His first implementation of this “cockpit” has been 30 years ago on the C36 military. So choils/humps binome are clever and great for avoiding a non locking blade to close on your finger. This is a must have !

So here we got a legal folder with a non threatening blade, strong non locking spring, great geometry and stellar particule metallurgy steel.
What not to love in this wonderful Urban ?

You can cut a pizza in your plate and use it as a steak knife without raising any eyebrows. I use my knives in plates and I know how to avoid to get them dull on the plate ceramic. My mother in law is never putting a knife near my plate, this is how I can spot where I’m going to sit on her table eventually.

Also the Urban got the perfect size to be carry in A 501 watchpocket, and as you can see mine has been shredded by many aggressive G10 handles before massive sanding.

So I highly recommend this great exclusive little knife, again it is not cheap but quality is there from the tip to the clip.
