Getting a convex edge with the CPM-15V blade of the Houlahoula Para3 Lightweight.

12/02/2025 nemosandman 3 Comments

I have enjoyed the Para3 in CPM15V for a week now and after the first pictures, one of my friend Alexandre wrote to me “Looking forward for a convex edge”.
And I have answered to him that I was not in a hurry to do it on this little wonder of modern cutlery. The steel seemed so hard !
But guess what ? What’s bred in the bone will come out in the flesh.
After a week of frustration trying to get any good (spectacular) result on leather and white ceramic….

Some gaffer is on the blade to protect it from any scratches.
My goal is just to “de-shoulder” the edge, to round it for a better leather stropping experience.

It is not rocket science and I’m clumsy and impatient.
So I’m not helped by natural tendencies.
As you can notice the edge near the guard will have less attention.
My friend JD is able to go even but I’m not to his level in making beautiful edges.

But as you can notice it is getting better.
I use a Double Stuff 2 from Spyderco. Mine is old and the glue between the ceramic slate has gone. The diamond slate is not as efficient as some decades ago but it should bite into CPM15V despite its humungous pourcentage of vanadium.

“Since CPM 15V has a high volume (23%) of vanadium carbides (87 HRC) which are harder than the ceramic alumina abrasives. (79 HRC)

That means 23% of the overall microstructure is being pulverized, burnished and adhesively worn to shape rather than cut at the apex.

Over the years I’ve observed a pattern in some folks complaining that these types of steels cannot get very sharp yet the same folks seemingly would refuse to use the abrasive that will cut the remaining 23% of that microstructure cleanly.

I do think that would be fascinating to do a controlled test and look at the differences between the starting sharpness and how that sharpness dies off with cut testing and then compare the loss of sharpness between the two with the same amount of cuts.

I’ve certainly seen this behavior in my personal experience, however, I’ve not documented and shared data publicly.

I’ve mentioned many times that my current favorites for sharpening are the bonded super abrasives rather than the electroplated abrasives. However, there is a cost difference, but in my experience it certainly pays for itself and has better performance.“
Shawn Houston on the Spyderco Forums

First look at the result.

Humm it needs to go one more round.

Ah, I am starting to enjoy the result and how the steel takes the light on the belly of the blade.

Now time to put some white compound polish on the leather.

Again I’m not focusing on getting it sharper it but just to polish the edge and remove any scratches. I want a better geometry like I use to have on the Para3 in M390.

CPM15V does not like to give away its particules.
When I have been able to get mirror edges on D2, 52100 or SPY27 I’m not able to get it on 15V. I need certainly to upgrade my equipement and my game for that.
I will polish it on Jade stone and post better results in the coming weeks.
So far I’m happy with the result. More to come later as 15V is not as easy as I thought to work on (JD adviced me “I think diamond past would help with the stropping. Diamonds or cbn can cut the vanadium carbides, of with this steel has a lot”. Not impossible, especially with diamonds but easy. Maxamet on the other side has proven to be much easier to restore even after catastrophic damages.
But I’m very happy with that Para3 which could be the HoulaHoula (*) of folding knives.

(*) Houlahoula are little birds with big balls and when they land they sing “Houla ! Houla !

On the Spyderco Forums Shawn Houston was kind enough to give some advice about how to get a mirror edge on CPM 15V:

“I recommend skipping the White Ceramic and Jade.
23% of the matrix in the 15V is harder than those abrasives.
A bonded diamond/cBN stone should help with the desired finish.

You deburr the best you can with light alternating passes on the stone. From here, the edge should be sharp enough to cut paper cleanly before moving on. Afterwards, go to a leather strop loaded with 1um Gunny Juice and use alternating edge trailing passes.

This is a good benchmark; keeps the “bite” at the edge without smoothing out the slicing effect. It also helps keep the “grab” at the edge for draw cuts but still keen enough for push cuts.

There’s different kinds of stones. They’re not all created equal.
You can take a diamond stone with the same abrasive and the same grit and it will leave a different surface roughness depending on the construction of the stone.
Yes, there are three major types of bonded stone.

Metallic, resin and vitrified.

There’s even some that are hybrids. However, these are not the same as electroplated diamond abrasives.The work more like regular water stones with better surface finishes.

“Diamond or CBN are the way. You can put a functional edge on 15V with ceramics, but if you’re wanting the real performance 15V has to offer, you need to sharpen with abrasives that will cut the carbides in the steel.”
Wandering_About on the Forums has sum it up.

Shawn Houston was also kind enough to share an AI summary of Instagram Reviews.

“Based on the latest set of reviews, BBB CPM 15V steel demonstrates exceptional performance and user satisfaction.

Performance:
* Excellent edge retention: Maintains a sharp edge for extended periods, even with demanding use (e.g., cutting blackberry roots, heavy use).
* High edge stability: Resistant to chipping and rolling, even with hard use.
* Versatile: Performs well with different edge angles and finishes (from toothy to mirror).

Comparisons:
* Compared to K390, Maxamet, S90V: Sharpening is considered easier than K390 and Maxamet.
* Compared to M4: Sharpening is considered comparable in difficulty to M4.

Key findings:
* Sharpening Ease: Despite its high hardness and carbide content, 15V is surprisingly easy to sharpen. Users report successful sharpening experiences on a variety of tools, from diamond stones and CBN plates to simpler systems. Burr removal is consistently described as effortless.
* Edge Retention and Stability: 15V exhibits excellent edge retention, maintaining sharpness through demanding tasks and heavy use. It also demonstrates high edge stability, showing resistance to chipping and rolling.
* Versatility: The steel is versatile, capable of achieving both aggressive, toothy edges and refined, smooth edges.
* User Enthusiasm: Many users express high levels of satisfaction with 15V, with some even considering it their favorite steel.
Overall:
BBB CPM 15V appears to be a top-tier steel that effectively balances exceptional performance with user-friendly sharpening characteristics. Its combination of edge retention, stability, and ease of use makes it a strong contender for demanding tasks and a highly recommended choice for knife enthusiasts.”

Spyderco Para 3 Lightweight 15V Sprint Run – C223PBN15V – First glimpse at the Lil’Brown Bear !

05/02/2025 nemosandman 3 Comments

Jumping on the Para® 3 Lightweight Brown CPM® 15V® Sprint Run® wagon was an easy choice after a month of watching our American friends review this new CPM-15V batch.

Following the Manix 2 release two years ago, showcased in the Reveal 11, and a Paramilitary Brown version, here is the chance to test this remarkable steel on a lightweight platform: the Para 3 in brown FRN.

For record CPM 15V is “Boasting almost a 15 percent vanadium content, this remarkable material offers the highest wear resistance of any cold work tool steel available today. The full-flat-ground, satin-finished blade of this knife is further enhanced by a specialized heat-treating protocol developed by acclaimed custom knifemaker Shawn Houston. The result is a blade that offers extreme sharpness and unparalleled edge retention.”

Shawn Houston is known as Big Brown Bear on youtube and his skills in metallurgy and knifemaking as drawn the attention of the Glesser’s family.

In 2018, he has written on the Spyderco Forums that request:
“Sal, Can we get CPM 15v?
“I like this steel. It’s easier to work with then Maxamet and Rex121.
Takes a killer edge and seems to be more stable then s110v.“

Larrin Thomas even answered:
“You guys are crazy. But with Spyderco anything is possible.”

And in 2022 a first Spyderco knife designed by Shawn Houston in 15V with his own heat treat protocol was proposed. Eric’s Manix 2.

“The CPM 15V Sprint run was supposed to be a surprise treat.
Eric wanted to share the CPM 15V with the custom heat treatment I worked on for my folder design.
His idea was to use a standard model so people can get their hands on the steel. Which I thought was really, REALLY cool of him to do that.
Working with Crucible and Niagara Specialty Metal we were able to select a specific melt of the CPM 15V that would respond best to this specially developed custom heat treatment.
So, Eric and Sal really went all the way on this, no other production knife company on the planet would do something like this. Eric and Sal are one of a kind.
You guys need to understand this is very unique having actual knife/steel/sharpening/edge people running a knife company that can cater to enthusiasts.
Originally, I was given options for different handle scales for the Manix but the most important priority was to get the CPM 15V Manix out as soon as possible so it didn’t make any sense to use exotic scale materials.
G10 is a great material to work with and brown g10 was selected because “Big Brown Bear” aka Triplebhandmade. (Me)
I am aware as many others that brown g10 is not unique to this model.
But the color of the handle scales and the handle scale material are irrelevant to edge performance and the most important priority was getting this out to you guys as soon as possible.
Looks like the price is great too, if we used carbon fiber etc cost would have been higher.
So, I hope you guys can respect that.
The folder collaboration design was being pushed back due to production capacity being completely full at Golden.
Please understand that I’ve been very persistent at wanting the knife made in Golden come **** or high water; I would wait until the stars burned out.
Spyderco has been very busy increasing the size of their golden factory to meet the insane demand of the current knife industry after the global pandemic.
Keep in mind, when a new product comes through the factory, they have to train the staff on how to make them, and what the best procedures are for creating that specific model in high volume with maximum efficiency. So, there is hidden effort when new designs come through at Spyderco.
Folks need to remember if we want this folder made in Golden (my favorite factory) we have to be patient.
My dream is to have a Golden folder we can all experience together.

I’ve gotten a chance to meet the people from the Golden factory I must say I’m even more excited about the idea of it being made in Golden. I’ve talked to the people that do grinding and heat treatment and there’s just something special about being able to talk to the folks that make your collaboration knife design.
So, I keep pretty quiet about the folder because I don’t feel it’s necessary to see get people excited about something that doesn’t have a clearly set date of exactly when it can be expected and I don’t want to put any undue pressure on Spyderco because they’ve been working very very hard over the past couple years to get things that sometimes people take for granted and expect to magically appear on the shelves to buy.
While I haven’t been posting in this thread everyday, I really appreciate you guys making sure to let Spyderco know this is something you want.
So, thanks for always updating this thread and talking about it on social media.I really think you guys will like this knife and I can’t wait to get one in my pocket one day.

-Shawn“

Now this is new batch including Microjimbo, Yojumbo, Yojimbo2, Native, Military 2, Para3 G10 and Para3 Lightweight.

Like all its brothers and sisters it boast the BBB logo proving that the blade has followed Shawn Houston heat treatment.

In his excellent vidéo Shawn share his first impressions and also check the hardness of his Para3 and the result is 65.4 HRC ! Impressive !

Framed from his video: he performed five separate hardness tests just to be sure. It’s well known that Shawn Houston’s special heat treatment — refined over years and tested by renowned professionals — brings out the quintessence of CPM-15V, elevating its performance to exceptional levels.

“Well, most heat treatment protocols are for tooling, like the ones in datasheets — not really optimized for things like edge stability.”
— Shawn Houston, on his own heat treatment

In practical tests, Pete from the Cedric and Ada Gear and Outdoors was able to cut through a rope 2,000 times without compromising the edge.

The action on my new Para 3 is perfectly smooth. I notice a little lock sticking but this is not an issue in my book.

And smooth enough that nothing unscrews on it — the blade closes like glass, effortlessly and precisely.

My Para 3 arrived perfectly centered, but with some burrs on the scales.
(A burr is a raised edge or small piece of material that remains attached to a workpiece after a modification process.)

You can feel these tiny imperfections under your finger along the FRN edges.

I have “deburr” it with some diamonds rod. Nothing fancy but now the handle is fine. I don’t remember having that issue on my previous Para 3 review.

The edge is even.

I don’t see myself working on a convex edge on this one. Not for the moment.

The sharpness is high and that blade is a hair popping sharp razor right out of the box.

I have already cut my self with its very pointy point. My Para 3 is baptized !

Now it is truly mind.

It is said that CPM-15V loves leather for a crispy edge.
(S90V or M398 for example don’t care about stropping…)

I’m curious how its 68 grams will compete with my Maxamet Para 3 G10 (98 grams) — sturdy yet smooth as velvet.

According to Spyderco:

“The term ‘lightweight,’ or the use of injection-molded handle components on a Spyderco folder, isn’t just about how the knife tips the scale. It’s about taking full advantage of the remarkable properties of FRN and FRCP, as well as our decades of experience as an industry leader in their use.”

So yes, this is a “light” saber.

The edge appears ground thinner than on the notoriously brittle Maxamet blade. Both blades receive special attention: the spine is smooth under the thumb, and the edges are expertly bevelled.

The chance to have such a steel on a lightweight folder would make it a great hunting knife like the Michael Walker ZDP-189 was in his days.
The game’s fur is very abbrasive. CPM-15V could be even stronger than ZDP189 on the joints, more permissive.

Ericasedc has made a video about that:

She seems really happy with her Para 3 since she has received it. You can see all the videos she has made on her channel about the Para 3 15V.

Anyway, going in the woods equipped with a Tenacious CPM M4 and a Para 3 in 15V would be a great combo nowadays.

Now that I can carry the mighty CPM-15V steel in my pocket, I’m eager to test its performance over the long run. Stay tuned for updates on this page or in another chapter.

Having a featherweight folder equipped with such a formidable blade and steel is uncanny — it packs remarkable power in a pocket-sized package. I still remember fitting the Maxamet blade on my red FRN Para 3 just to experience that sensation of a powerful engine on a lightweight platform.

This Para 3 Sprint Run is already a triumph, offering the chance to experience a remarkable steel crafted by passionate knifeaholics.

As mentioned, I have no intention of convexing the edge for now — I’m trusting Shawn’s expertise. Unlike AEB-L, which can be thinned while remaining strong, CPM-15V is packed with carbides, so I’ll stick with the angle specified by Spyderco and Shawn, which is already thinner than Maxamet.

But now, the real fun begins: testing!
Spoiler: the combination of geometry and steel makes it an excellent whittler — the blade cuts deep, and the wood feels incredibly smooth under the cut.

Final word of this review are from Shawn Houston who was quoting and answering to Todd from Scienceofsharp.com about 15V (as Todd’s goal is to increase our understanding of the role of carbides in cutting performance and how different sharpening techniques “interact” with the carbide):
““tremendous pleasure in using an extremely sharp knife or tool (and satisfaction when you have sharpened it yourself). Even though it is often a fleeting experience”
That’s the “idée fixe” of it all.
The little smile and feeling of elation when the edge lasers through material with zero effort.
The stones, geometries, steels, heat treatments and the techniques.
Chasing those fleeting moments of joy with high performance and riding the line between madness and clarity in trying to understand at the most intricate levels how it all really works.
An insatiable quest.“

“The Edge is a Ghost. Always changing. Dying (dulling) being reborn (sharpened) split personality (angles and geometry changing).

Think of the edge as gas in a vehicle. It runs out of gas and you put in more gas. We provide the format, materials, design for use, variety to avoid boredom and create interest, but the edge is your creation. The result of your understanding, education, experience and practice.”

Sal

“CPM 15V is a very difficult steel to manufacturer, so it may not always be available in the future.
Crucible Industries LLC went to great lengths to produce the steel, it puts a great amount of wear and tear on the ceramic refractory designed to hold the super heated liquid steel during melting. This is necessary to dissolve the vanadium carbides to the very fine sizes that we see in the finished product.
It’s quite a marvel that’s not often appreciated.
15V is basically the commercial limit for how much carbon and vandium they can get in a steel for production sizes batches.
The benefits of this to the end user combined with excellent heat treatment is a enjoyable, lasting cutting experience that also touches up at the edge nicely with proper abrasives and sharpening experience.”

Para 3 blades swapping on New Year’s Eve

31/12/2019 nemosandman 1 Comment

I got two Para3: a M390 Lightweight and I got a Maxamet Copper handled.
The Lightweight is so good, I wanted to use the 70 HRC blade on that plateform.
Nothing wrong with M390 which is just a great EDC steel with stellar performances but staining steels are part of DNA.
After watching Nick Shabazz having the same idea and filming it, once the novelty of the M390 faded away, I have decided to step ahead. It was really easy to do it but for the stoppong pin of the lightweight (Torx 6) which was dismounted with two tools as it was turning inside the handle.

Easily disassembled copper scales.

Now mounted on the lightweight handle.
For more about disassembling a Para3 lightweight here is Eric Glesser’s Video.

Here we go: two excellent knives. As you can notice they are users.

I have been able to thin the edge of the M390 when the Maxamet refused to give away any particules…

The Spyder logo is golden on the M390 and black on the Maxamet.

Perfectly centered blades on both and smooth action with no lateral play.
Here my Little Red Hoodie ready for tonight 24 oysters opening.

Happy Saint Sly everyone !

Maxamet being more denser it has add 3 grams on the scales.

Spyderco Para3 – Let there be light!

30/11/2019 nemosandman 6 Comments

So here I am, minding my own business. (Always wanted to start a review with that kind of sentences… à la Michael Di Mercurio.)
I love heft. A heavy knife is sexy in my book.
Bought in the 80’s, one of my German version of a Buck110 was an anchor and I loved it.
I dig the Fred Perrin PPT for its massive butt balance but I’m quite certain Fred would love a lightweight para3 as he loves to hide light tools on himself. 😉

But now.

Now Spyderco has always been about Performance. Performance in geometry, ergonomics, in locking mechanism, steel’s heat treating, choice of materials… and refining refining and refining… Constant Quality Improvements they say.

That Para4 lightweight is born from that CQI state of mind.
Remember the Military ? It always been a lightweight because every kilograms counts when you are carrying a weapon and ammo. At first the C36 was using only one nested liner if I remember well. The fight against weight was hard and not understood by many.
Just look at some heavyweight folding brick found nowadays… No comment.

So Sal loves sport cars and racing boats. His passion for sailing is oozing from his designs.
He has just release a lightweight version of his Police knife.
That Para3 got only one liner like is first Millie.

So lightweight is an obsession as much is lock reliability in folders.
Just like in the Ford V. Ferrari (Le Mas 66 for Europe) james Mangold’s movie.
BTW Spyderco has just release a Lightweight Sage with a compression lock too.

You need need to have a great confidence in the materials you are using too to implement a Compression lock in a plastic handle because the lock needs tension. But FRN is considered as strong as aluminium and Fiber Reinforced Nylon is something Spyderco explores and masters for more than 25 years now.
I remember self defense instructors driving with their trucks on their FRN Delicas (pre liners version) just to show how strong this lighweight folders were.

The lightweight handle brings also great balance to a very “alive” knife. The Para 3 lightweight is something your enjoy playing with. It can be open and close it in a blink. This is really fun and elegant.

The texture is perfect when my hands were wet and greasy. The Bi Direction Texturing is perfect near the pivot: my thumb meat is gripped by the FRN in the forward direction.
It feels so secured in my wet hands ! Also the bi-texturing works in the other direction for pulling the knife out of the pocket. In term of security, not dropping your tools which is like glued in you hand, it is a must. The wonderful Carbon Fiber of my Kapara can not compete with that. It feels like a soap compares to my Para 3.So for the pragmatics, you can reach for your knife, pull it out and use it even with oil on your hands. This is so great and really rare in the knife industry. Sal’s inventor’s mind again.

Like many compression locks including the beautiful Kapara, you can get soared hands when using the knife without gloves. It comes form the area on the top of the pivot which bites your hand skin. My friend Pascal got reported blisters from his Paramillie 2 for the same reasons. The space between the thumb and the index needs to have a surface to rest or it will hurt. Some Youtubers got that issue when cutting ropes for edge testing too.

This details has been featured in the Ray Mears Wolfspyder. You can use your knife for hours !

See the difference ?
Whittling and bushcrafting ask for the maximum of confort.

Also look at the C36 Military: again there is a surface to rest your hand avoiding soar and blisters hence its great ergos when whittling.

So let assume the Para3 is a light user or at least design as such. Nothing bad about it they are plenty of other designs and even better great fixed blade like Puukkos when working on wood and hard materials for a long session.

But what a great light user it is. It is versatile. With a powerful blade and solid point.
Easy to clean. Anti slippery handle. Non threatening design. Light and invisible once clipped. What not to love about it ? This is a milestone in my book.
And I do favor heavy knives. My Maxamet Para3 got a copper handle.

I have thinned the edge to my taste.

And now the leather is enough to keep it razor. M390 heat treated by Golden is a must.

Para 3 Lightweight DLT Trading Exclusive – C223PRD – My Little Red Riding Hood !

09/11/2019 nemosandman 1 Comment

It is light, it is red and it is cute and can skin a wolf or granny’s apple ?
DLT Exclusive M390 steel blade on the Para 3 Light plateforme has hit the old continent after NOT taking any shortcut… It was stuck in Paris airport for a week !Action is perfect. The blade is centered. Drop chute works perfectly. This DLT Trading Exclusive is clicking all the right buttons as I was not really excited to test this knife without some spicy exclusive steel.
Bringing the compression lock to the FRN is a Tour de Force Eric and Sal can be proud of.
At 69 grammes it bring a very strong little big knife into the “pocket and forget” realm.
This is going to be a very Sheeple friendly knife thanks to its red scale and deep carry clip.
I love high performance blade on FRN. My Manix Lightweight is a CPM 110V version and my favorite holiday knife as it is easy to put in a luggage and keep its sharpness for weeks.
This is Little Red Riding Hood is destined to de-throne it. Less moving parts, easier to clean. Very impressive quality !
And M390 heat treated by Spyderco is a sure value since 2012 ! :-)More to come soon as right in the pocket it goes ! Riding !“But Grandmother! What big teeth you have,” said Little Red Riding Hood her voice quivering slightly.My own copper Maxamet Version is just a really heavy weight.SO LIGHT…
“The better to eat you with, my dear,” roared the wolf and he leapt out of the bed…Deep carry clip and excellent lanyard hole placement.

Spyderco C223GPDGY Para 3 Maxamet Part II.

12/06/2018 nemosandman 5 Comments

The Grey Mouser has been in my EDC rotation since it has arrived in my pocket.
So this a little report.

Maxamet is like a super CPM M4 to me, it cannot seem to get dull. I have deshouldered the edge and keep it sharp (razor) with white ceramic and leather. The edge behaviour in wood is like M2, it gives a gentle patina to the part cut.

The gently rounded spine is a must for thumb push cutting.

The lock is solid and did not give in to any vertical or lateral play.

The Para3 is really a friendly 3 inches knife with a wide spectrum of uses.
Near the pivot you got as much as any C36 Millie strenght for power cutting as this is the same “cockpit” as the good old Military. The point is easier to control as your hand grabs the blade and the handle with more ease on smaller knives. So you got a very capable knife for the outdoors, able to carve and trim wood.

Maxamet is giving a beautiful orange red patina. I have not been able to get any pit of rust despite my every day use on acidic foods.

It’s less sensitive to medium than K390 and close to CPM10V. You got stain but nothing more in my experience.

I clean it directly under the tap of in a soapy water. Nothing extravagant. The action is on the smooth side even without any oil near the pivot. I have decided to treat it the hard way.

So far I’m really impressed by the ease of keeping razor sharp that very special alloy. It’s not difficult with only white ceramic and leather and it happen once a week just for a refresh.
The deep carry clip is back for tip up carry and it makes a very low signature for an EDC.

It’s used every day for eating and mostly I use the spine to push in the plate.

An apple a day keep the doctor away, especially if you got a good aim.
More to come soon but so far this is a very satisfying experience.

Spyderco C223GPDGY Para3 Maxamet — The Grey Mouser.

10/04/2018 nemosandman 6 Comments

It has been half a year of patience before my pre order turns into a mail call. Howard Korn from the Knifecenter.com was kind enough to send it to me as soon as he has received it. It was a quick 6 days of travelling from Fredericksburgh, Virginia to Paris.
The name of this Para3 should be”Desire” but it will be “Mouser” in honor of its color: grey. Also in honor of its almost magical alloy used: Maxamet.

What is Maxamet ?
According to Spyderco its full name is “Carpenter® steel’s Micro-Melt® Maxamet® alloy”. “Maxamet is an extremely hard high-speed powdered tool steel possessing properties that transcend conventional high-speed tool steels and approach those of cemented carbides – the ultra-hard materials used to machine other steels. When Carpenter developed this amazing alloy for the rollers in their steel mills, they sent samples to various companies in the knife industry to evaluate as a blade material. Although many tried, Spyderco was one of only a handful of companies to successfully develop the specialized methods necessary to machine, heat treat, and grind this demanding material to yield reliable, high-performance knife blades.”
It so difficult to work with that it has given some headaches to Eric and Sal hence the 6 months late in the production of that Para 3.
Maxamet should have better performance than CPM110V. Now that I got both steel, I will try to see if I feel and see a difference.
What its composition reveals ?
Carbon 2,15% ; sulfure : 0.070% – 0,23%; chromium : 4,75% ; vanadium 6,00% ; manganese 0,30% ; silicium 0,25% ; cobalt : 10,00% ; tungsten 13,00%.

It’s not a stainless steel it’s an high tech tungsten alloy !!

Here its data sheet in Carpenter’s.

The wear resistance of Micro-Melt Maxamet alloy is better than that of conventional powder metal high speed steel grades and is equivalent to AISI A11 cold work powder metal tool steel. A11 is CPM 10V. Better? How much better ?
According to Cliff Stamps: “Maxamet is an extreme alloy, for comparison, it is to 10V what S90V is to 420J2. Maxamet is used when HSS like M4 fail because they are too soft or wear too fast – just consider that for a matter of perspective.”
(For the record he’s not talking about CPM M4 which comes from powder metallurgy process but good old M4HSS.)

So far Mouser is shaving my arm’s hairs which are flying of its blade. Its factory edge is really thin. With that amount of tungsten it should not be sensitive to its final tooling in the Golden plant. I’m not planning to work on it yet and keep it that way for its first run.

Its complex heat treatment and the HRC should be on the very high..

Spyderco is offering that steel on many knives: not counting a Mule but a LW grey Manix 2 , a G10 grey Paramillie 2 and a lightweight grey Native…
The Maxemet version is not a Sprint run.

I have also noticed the chamfered work they have made on the spine and the spyderhole and the jimping behind the hump. I don’t have to use my diamond rat tail file anymore !!
Thank you Golden ! 🙂

Also the blade has been gently beadblasted which gives it a very industrial look. The grind is perfectly symetrical as always on my Colorado’s made.

The thick grey G10 slab also concours to give that toolish look, again the attention to detail are stellar. There is nothing to change when you open your black and red box.

So far what I have changed is the clip, as I don’t plan to spyderdrop this little guy.
The smooth compression lock permits a lot of other way to open it elegantly.
Also I have sanded the G10 to smooth it to my taste and keep my pocket lips healthy.
I keep the pivot area rough for the ergos.
Now the game is on, let see all this fuzz about that Maxamet steel !
Spyderco catalog’s sheet is here.

EDIT: Eventually I have gone back to the OEM hourglass clip in a Tip Down carry option.
Because it’s so fast to draw like a I do on my Millie and Paramillie 2.
The spyderdrop is so elegant and bound to the spyderhole: it works like a breeze.
Also I have starting to test the sharpness which is uncanny right our of the box.
I did not have that kind of result with its S30V bro. The Maxamet thin edge goes through the plastic bottle butt to make tagliatelle !! The edge is really hungry.

Also my previous review on the Para3 is here.

Between both knives there is a little difference. It is the sound of the mechanism.
The opening and locking on the S30V version will be a TAK.
When the opening of the Maxamet version will be a TIK.
The pitch of Mouser is much higher. Different alloys, different hardness produce different sounds.

The Mouser is a small (not much more than five feet) mercurial thief, gifted and deadly at swordsmanship (often using a sword in one hand named “Scalpel” and a long dagger or main-gauche in the other named “Cat’s claw”), and a former wizard’s apprentice who retains some skill at magic.
The cynical-sounding Mouser is prone to showing strains of sentiment at unexpected times. He’s a rogue, living in a decadent world where to be so is a requirement of survival. It was created by Fritz Leiber.
Part II is here:

Spyderco PARA 3 G-10 Black on Black C223GBK — The Black Panther Cub

05/03/2018 nemosandman 2 Comments

This is my first Para 3 and also my first black coated Spyderco blade.
According to Spyderco:

“For tactical end users who are concerned about light discipline or those who just prefer the look of a black blade, the Para 3 is now available with a tough Diamond Like Carbon (DLC) blade coating. This low-profile coating is permanently bonded to the premium CPM® S30V® stainless steel blade…”

Cool I do really love DLC as it’s really scratch resistant. The primary reason for blade coatings is to reduce the reflective properties of the steel. Shiny things draw the wrong kind of attention and in a military environment, can tend to get people shot. However, like anything else intended to be used in a military environment, coated blades are not immune to wearing off but DLC is really strong.

I also specifically love DLC for adding corrosion resistance. The area which normally rusts on an EDC is in the pivot area. No worries about that with a DLC coated blade!

The new Golden Co. factory is bringing some of the best quality in manufacturing to date. My Para3 is absolutely flawless: perfectly centered, perfect smooth action… I had noticed that rise in quality on my last sprint run Para2 in 52100 too. Now Golden is as good as Taichung in quality control – if not better. So kuddos Colorado! Also Eric told us during the last Minimeet that they have just hired two new engineers who will make a real difference. Spyderco has developed a speed training of their own engineers as no school had prepared them for the knife industry.

Like the Paramillie 2 was a son of the Millie, the Para 3 is really Millie’s grandson. Same “cockpit”, stout hardchore 3 inches blade, smooth Compression Lock.

My all black version is very discreet and the the short blade makes it even less threatening. A black “commando” feel on such a short folder is almost like an tribute to military blades. On a short knife like this baby millie the “cute” factor is very strong.

My hand fits perfectly on that handle. That infact was a big question mark prior to holding the Para 3. You feel this short version of the Millie is ready for any task.

The DLC coating is absolutely stunning. I have sanded the G10 and put a great deal of care so to not scratch the steel hardware.

Here after some plastic cutting which scratched some of my other blades, there were no marks on the diamond hard coating. Let see how it will age.

At first I had mounted the clip for tip down carry (left pic) and experienced great spyderdrops. The Para3 is so smooth in its action, a middle finger is sufficient for opening.
As I got the opportunity to get a titanium clip from Massdrop (right pic), after transformation it’s now a tip up solution and a middle finger opening work best for me. After all, a black knife, even of that size, needs to be as discreet as possible.
