The Spyderco PPT Round 3- Long Term Review of a Faithful EDC with Supersteel.

31/05/2019 nemosandman 2 Comments

Since last year round with the PPT, the very unique ergos of this unique folder have made me come back again to its radical design and I have decided to EDC it in all circumstances (instead to keep it safe).

Still, I really enjoy how the weight of the handle glue it to my hand and I have found zero hot spots after filing a bit the choil. Smoothness of its action has been really enhanced by using it everyday. Now it deploys fast and close by gravity.
After some work on the blade, the edge has been thinned as my Manly’s.

The PPT is a very easy companion. My main battlefield is the kitchen. It is not an open handle design but with some hot water I have been able to keep the spacer and the skeletonized liners clean. A dip in very hot soap water is all my maintenance after a full day in the kitchen but a tiny drop of oil is then always welcome. It has been used in the woods where I was able to use it on wood. The knife has behave perfectly even when twisting the edge. Zero issue here. The chips are flying everywhere as the full flat ground is fast in making deep cuts in wood. While in the forest, when working with it, most of the time I have thrusted its blade’s point in a tree instead closing it and opening again.

No damage at all. For the record, Sal has developed and sold his own version of a Bushcraft knife, at first named the NASA Bushcrafter with S90V blade and Carbon Fibers handle and later the Proficient. It means that the melange S90V plus CF is approved by Sal for being used in the wood with reliability.

The lock which is almost a RIL lock has not failed me because your grasp reinforced it when you hold the knife in your hand. Zero movement vertical or horizontal. I have not been able to fumble my grasp when closing. The opening of the knife is now made with my major finger flicking it like.

I have sanded the handle (just a bit) to smooth the edges of the corrugated CF, just to protect my trousers from being chewed. Nothing changed in the look but the PPT is now much easy to retrieve and introduce in my denims. I carry it in my right front pocket along with a leather wallet.

Once brought to “razor sharp level”, S90V is easy to maintain to that level mostly only with white ceramic and some leather stropping. ( JD has given me some diamond compound that help the process too). After some cardboard cutting, the ultra razor level is lost but the working edge is keen enough to slit through paper and this sharpness will last for a very long time. Zero chipping even after various cuts into very hard plastics. It is almost a maintenance free knife, like my Manix in CPM110V which I use for travelling (It is light and stays sharp for a very long time avoiding me to bring some sharpening tool).

When cutting with the PPT you got a very agile blade with its center of gravity inside your hand and, by just holding it by its hole, it immediately orients itself tip up. It helps when you need to change your grip: it like a compass telling you where is the point and the very sharp edge even with greasy or wet hands.

Despite its martial pedigree, sheeples seems not afraid of my PPT. No raising eyebrows even when used in restaurant or family dinners. Nobody seems to notice it which is a very good thing.

Eventually if the PPT was a dog, it would be an Amstaff : compact, bold and powerful.

Spyderco C135CFP Perrin PPT — Portable Praetorian Tool.

26/03/2018 nemosandman 4 Comments

The first PPT was release eight years ago. It was the mind child of Sacha Thiel, Philippe Perotti and of course Fred Perrin which it got all the power. For the record Philippe Perotti aka “PP” was Fred’s student in knife making (and Fred was PP student in handguns). I still own one of PP’s Streetbowie made in D2 and also one of his great Commander knife made with Sacha Thiel which looks a lot like the Perrin Streetbowie.

Now the design’s goes in the stardom with a luxury amazing S90V / Carbon Fibers corrugated stunning handle.
This rude boy is a beauty like Marlon Brando in a Streetcar Named Desire or Tom Hardy in Taboo. It’s heavy in your palm. But this weight is a pleasure exactly like the Sharpfinger. Marc Animal McYoung in his book “Knives, Knife Fighting and Related Hassles” was choosing a butt heavy short knife over any other. The weight is like an anchor in your hand as the knife handle is cuddling inside your palm. You find the same idea of weight distribution on heavy butt first Streetbeat.

Talking about the handle, this macro-texturing shows a wild side of this tool.

On this picture you can notice the unique clever sturdy lock. It’s made to be secured once the handle is hold tight.

The steel liners and the full steel back spacer, the full steel construction, while sturdy, makes for a dense carry. Knowing Fred, being able to use the “pommel” as a crowd pleasure won’t be a surprise. Anyway it’s a tool which can certainly be used to drive a nail in a plank.

Let’s compare with a titanium folder, the Spydiechef.

It’s a matter of taste but I love it as the balance suits me.

In eight years the Taiwanese manufacturer has refined his production.

The choil used to be a hotspot in the first version. No more now, there is absolutely no hot spot but… the clip.

The way it’s stand with a point proud point …it’s really not the best SPyderco clip just compared with for example… the Lil’ Lionspy great great spoon deep carry clip !!
The point/end of the clip needs to be parallel to the handle as this one is an invitation to scratches cars doors and catches things.

But its zips easily inside the pocket. It’s a no brainer.

Like the Spydiechef the design of the PPT notice how it give you a lot of power in case of cutting on a board. But the PPT won’t be as easy to clean with it’s squeleton thick liners but nothing which cannot resist to some hot tap water.
This new incarnation got a very thin edge. Those full flat ground blade in S90V provided by Spyderco lately are a pleasure to use and performance oriented.

But its true brother in law could be the Yojimbo 2.

The PPT got a very strong spirit, mix that with Sacha Thiel attention to details and Philippe Perotti pragmatism and you got a very powerful EDC which can be used by soldiers, firefighters, hunters, cooks, collectors and bushcrafters.

A little edit: after some EDC carrying and using.
Of course I have started to de-shoulder the edge and gives the PPT a more friendly way to get strop on leather.
Ergo wise, this heavy butt is really addictive. It works like a magnet because of that handgun handle. For the record La Griffe got a Derringer shape handle too which is also heavy compared to the blade. It makes your tool almost jumped in your hand and really anchored it in your palm while the perfect radius of opening makes it a very fast and safe opener. The meat of your finger is caught by the sharp hole and SHLACK !! It’s really one of my fastest tip up carry opener so far.
Why is the PPT a tip up carry ? I remember Fred bitching about the way some newcomers (back in 90’s) who were providing RIL locks with a tip down carry: the clip was in the way. What Fred loved in the RIL lock on the Sebenza was the way the hand will secure the lock. With a clip attached near the pivot, you could not squeeze the handle anymore and secure the lock.
So the PPT reflect all those years. It’s a real biker friendly design, like the La Griffe has always been. Bikers are modern world horse riders. The PPT would a horse rider best friend too.
In the part 2 the rider could be a nightrider ?

Yojimbo2 vs Paramilitary2 — Face 2 Face !

31/10/2017 nemosandman 2 Comments

I got two requests for writing that little comparaison hence a lot of users are hesittating between those two radical designs.

My Yojimbo2 is a special edition as is my Paramillie 2. Both got carbon fiber handles. Both are made in Golden, Colorado, USA, Earth. Both are second generation.

The Yo2 has been designed by Michael Janich and The P2 by Eric and Sal Glesser. Both got compression locks and inhouse system invented by the Glesser. The Yo2 got an S90V blade and the Para got a 52100 ball bearing blade.

The steel in those exclusive runs are totally opposite. S90V is a powder metalurgy alien steel named CPM420V in the previous Century. It is like some kind chewing gum alloy which refuses to let got any particules even during sharpening when 52100 is more of traditionnal old timer bladesmith steel of choice with carbon and a pinch of chromium. S90V got carbid of vanadium and chromium and more than 2% of carbon. 52100 got 1.2% of carbon. They are on the two opposite sides of the famouse best steels spectrum. S90V will stay sharp more than 3 times longer than 52100 if used on abbrasive material like cardboard. But 52100 will be easy to reach razor sharpness. S90V loses its razor edge very fast before to keep a plateau of working edge for a very very long time.

Both knives got a convexed edge, it was a bear to obtain it on S90V.
Both got very pointy tips fir a equivalent lenght.
But the Yo2 blade is saber hollow ground when the P2 is full flat ground.

On wood I have already noticed how great the Yo2 was for making sticks.
It has a very confortable handle for hard use and the keen edge got full power from the choil to the tip. Also the thick back helps a lot for pushing with the thumb.
Try the Yo2 on sticks: it will amazed you. But if you need some belly, the P2 will be obviously better. You won’t take the Yo2 for an hunting knife at all.

The Paramillie got this wonderful performance and control the full flat ground can provide. It is in his element: reliable and steady.
But the Self Defense knife is not the last in performing camp task. Do not underestimate it in that mattet as Michael Janich always advocated to use his knives to get used to their ergos and the way you carry them on your person. the more you do it, the more you train to to draw them in stress situations.

But in pure quick drawing, the Paramillie got a serious avantage: you can easily spyderdrop it. It is opened in a breeze just by drawing it by holding the hole. This is fast and actually faster than the Yo2 which required first to be clear from the pocket.
Both knives are equally smooth. The YO2 got a little more momentum because the blade is heavier. But, in my book, the Self Defense knife is beaten by the utility knife.
The Yojimbo got also more presence than the Paramillie2, it is like one of wolverine claws and not really sheeple friendy.

So really it just a matter of look and taste if you need to choose between them.
Both a high performance folders, with great locks, great ergos and an attention to detail breed in a second generation design. Both will find a way to be very useful in everyday chores. They are false brothers but you know…
Now, the world don’t move to the beat of just one drum,
What might be right for you, may not be right for some……

Spyderco C22 in ZDP189 — Amazing After Six Years Hunting in Tuscany !

05/10/2017 nemosandman 5 Comments

Six years ago, my friend Valter Nencetti took my Walker for a one year mission which turned into a six years journey. It was his favorite knife for hunting and he reported that to me in this article: https://nemoknivesreview.com/2012/12/30/spyderco-c22-in-zdp189-italian-hunter-update-by-valter-nencetti/

This year, he has given it back to me after I had offered him my Native 5 in 110V which is IMHO an upgrade for Hare Hunting. The Backlock of a Native 5 is a perfect lock for that kind of use, but you can notice the Walker lock as not travel very far. The curved concave notch prevents it to go further.
There is absolutly no play !

For the record skinning hares is not an easy task for an edge as the hairs and the skin are ruining the sharpness very fast. There is a lot of dirt which acts as abbrasive. I have made a video and soon will put it on line.

Being used everyday, Valter eventually broke the clip which is a very fragile part of the walker compared to spoon clips used noawadays in spyderco line. You can also see it was not clean everyday and used as an EDC in the countryside of his beloved national Park in the North of Florence in Italy.

You notice the normal wear on the handle but Carbon fibers is incredibly sturdy as an slob material. It can be easily cure with some 1000 sandpaper work.

There were also no pitting on the blade or on the liner lock. ZDP189 is known for pitting strangely with its 3% of carbon and 20% of chromium. But here anyway, no issues.

I have started to clean the marks on the blade with some sandpaper.

Then I have restored the edge to razor.

No chipping.
No pitting.
No blade play.
No marks on the handle.
A broken clip.

Valter used his knife with no afterthoughts. I know it was not used on wood but mainly as a skinning tool. It has processed hares but also been used on boars and deers. Also it was used on plastic and everyday mondane tasks as Walter is breeding hunting dogs.

That’s not bad for a little gentleman knife which is a true workhorse.

Yojimbo 2 C85CFP2 – S90V & Carbon Fiber

17/05/2017 nemosandman 6 Comments

Yojimbo Exclusive Run

“Number 17” has entered in my life yesterday as I was angry about an order blocked in the airport for 12 days. I had ordered a Yojimbo 2 (G10, S30V) and since the 5th of May it has disappeared from the tracking.
So yesterday I indulged myself with a very rare exclusive run for Knifeworks three years ago: a Yo2 with S90V and Carbon Fibers handle.
Better, I had ordered a deep carry clip and it’s now mounted.

My idea is to use the Yojimbo, not as a SD tool but as EDC tool. So this safe queen is going to see some mileage and S90V will be welcome for it’s very high abrasion resistance. This is my point, I hope the Yo2 will keep its own (point) sharp and solid.

Some intense sharpening was mandatory. The edge was uneven from one side to the other (3mm against 2mm)… Now it’s much better after some intense passes on the Fallkniven little diamond/black stone tool and the Spyderco ceramic grey/white.

And well, it works just fine.

Quoting Michael Janich about his own design on the Spyderco Forum:

“…With regard to the utilitarian function of the Yo2–absolutely. I grew up in pretty humble surroundings. Although we didn’t have much, my Dad was very smart and skilled with his hands. I learned that the best way to have stuff was to make it, so I used to spend hours making toys out of cardboard, scrap wood, string, and anything else I could scrounge. One of my most prized possessions back then was an X-Acto knife set my Dad bought me with all the different blade shapes. Initially, I thought the different blades were cool and spent time swapping blades to cut different materials and shapes. After a while, though, I realized that the standard straight cutting edge was the most versatile. If I needed precision, the tip did the job. At the same time, if I needed cutting power, the straight cutting edge transferred power all the way to the point.

The blade for the original Yojimbo was based very much on these experiences and the shape of a common utility knife/box cutter. It was designed before 9/11, but released after. Promoting it as a “box cutter on steroids” was not appropriate at that time, but functionally, that’s exactly what it was. The Yo2 does the same thing, but even better…”

And more from another thread:

” … Helping my Dad with DIY projects around the house, I noticed that most utility knives, electrician’s knives, and similar “trade-oriented” cutting tools were Wharncliffe or sheepfoot blades. Again, in practice, it made sense and they worked. I chose my first pocketknives–Case slipjoints with straight edges–based on that experience.

When I started studying combative knife skills as a teenager, I read all the classic WW2 books on the topic, many of which recommended Bowie-style blades with significant “belly” to the edge so they could be used to snap cut. My taste in knives changed as a result of that and I began carrying blades with more belly and well-centered points. My first commercial knife design–the Masters of Defense Tempest–even reflected that style. However, when I had a chance to design what ultimately became the Ronin, I went “back to the drawing board” and did a lot of live-blade cutting with everything in my collection. I found that the knife that cut best was actually my Spyderco C25 Centofante, which was a Wharncliffe. When I began to analyze and really understand the dynamics of cutting, I realized why.

Cutting is cutting, whether it’s utilitarian or defensive. For cutting power and dexterity in a small blade, the Wharncliffe really shines…”

There is nice video made by Michael Janich explaining his design here on Youtube.

And by the way, the collector is just using a Yojimbo2 (S30V/G10) as an EDC.
It got the scars to tell its story.

Team Cuscadi new Carbon Fibers Scale on K390 Urban.

16/03/2017 nemosandman 5 Comments

Why the change ?

After my Urban review I wanted a smoother experience. And give a more precious apparence.
Carbon fiber is a really sturdy material and twenty years ago you could only find it in Formula One and jetfighters.
The feel under the thimb is wonderful and the knife get clipped with ease.

Great work from Team Cuscadi and great service.

Zero Tolerance ZT0770CF – Fast and Furious.

07/02/2017 nemosandman 3 Comments

I love my Spyderco mantra 2.
Great engineering, ergos and materials. An attention to details and a signature: Eric Glesser. He is a perfectionist and a clever one. But I do hate one thing: the trademark “little” hole. A place to catch grim and hard to clean on the field.

Why don’t you just print a circle instead to drill into the blade ? The trademark hole is even on my Spyderco fixed blades…
Anyway, the Des Horn was a first step. A second step is the ST0770CF.

I was in need of a “blind” folder. I mean a folder without any hole or thumbstub or disk.
The Real Steal Megalodon was on my list: with its beautiful lines like a Sukhoi 27, M390 steel….
But then the Zero Tolerance caught my eye through all its great reviews.

ZT knives were always synonym of heavy fat ground knives à la Strider. Not something I would enjoy as EDC.
Unless I start to follow a special project around the ZT0770in M390 and especially a version in CPM M4 (ended with 69 dollars of international shipping fees).

So I went to “La Coutelerie Tourangelle” famous for their good prices, great shipping fees (5.9 euros with tracking in France) and total absence of communication…. 😉 Just kidding, even if they are mute like a brick wall, they delivered a great service world wide.

The ZT0770CF got no name. Its blade is beadblasted. This is a user not a safe queen.
The assisted opening is strong and seems reliable. I have found some people were able to remove the spring easily and even order another bronze washer. But my idea was to have a spring making my flipping secure and complete.
Many times my flipping was not 100% on my Southard on my Domino…. and it was frustrating.
So no ball bearing on the ZT but a strong spring. Again if you don’t like it, you can remove it.
I love it.
It is positive and definitive. SCHLAKK !! It’s open.

Now if you don’t want to be noticed you can open it against your leg, halfway and with a gentle flick it is open.
All is silent.

Balance wise, the ZT is perfect: the Carbon Fibers handle is so light. There is a black spacer, beautiful and very scifi. But the point of balance is just behind the pivot ! Perfect.
The knife is “alive” in your hands.
The texture of the carbonfiber is smooth but matte. Just like my sanded G10 handles. There is enough blade to open the knife like a gentleman folder. It won’t jump from your hands, the spring is not “that” strong.
There is a detent you can also feel at the end of the blade course.
The action is smooth, enough smooth to have the gravity works fine when unlocked.
This is a beautiful knife with a great attention to details.

The liner lock is thick and nested. Easy to operate. The detent ball is visible. Everything is in place.
The jimping on the blade is not to aggressive. The jimping on the flipper is more aggressive but do not come in contact with finger once open.

The guard is very cleverly thought. The position of the pin and the jimping on the flipper. It’s a clockwork !
Closed or open, there is no hot spot on the ZT0770CF, all lines flush together: very impressive.

The pivot screw is beautiful and despite its exotic look just need a torx to be unscrew. You can rest your thumb on it, it works like my Calypso’s screw guard.
The CF handle is renforced by nested liners and despite being light the construction is very solid.

Ergos are great. I mean they suit my four fingers. I already loved on my Mantra how the flipper served as guard once the blade open. Here on the ZT the guard in integrated with flipper like on the Domino but more pronounced. I really love that configuration.

The ZT got a particular blade: high flat thinly ground with a kind of sheepfoot shape. It works.
You got some belly near the pivot and a straight edge near the point, something between a Spyderco Positron a stretch Cricket.

It cuts aggressively and pass my plastic bottle bottom with force and ease. Eventually I find the ZT’s blade is simply gorgeous, all in curves… The belly near the pivot will give a lot of power for pushcuts into wood.

I love Elmax since my Lionspy. I remember beating the crap out of it and it was really forgiving: no chipping and great sharpness.
Also I’m in love with a Squeak in Elmax with titanium handles for a year now and this pure little Italian wonder will be review soon.

Elmax is such a great knife steel. No chipping, edge stability, ease of maintaining. What not to love ?

The black clip is short but made for deep carry. This is a very low profil configuration which leave almost zero print. The knife can find a nest into the watch pocket too. We got here a very compact package and very light: a true EDC.
