Limited edition "Sprint Run" CPM M4 Malanika Puukkos

Comprehensivist said:
I have only one Malanika Puukko so far and I'm quite impressed with it. I am interested in this project if I could could reserve one with a stacked birch handle.

Thanks for posting this thread.

Yeah Phil, love his work, he does those grinds freehand, no jigs yet so clean


They will be first come first serve when available this month in the coming weeks

His grinds and this steel should make this knife a real wood "laser"

Where exactly is the sales thread going to appear?

They will be Posted in the the custom knife makers sale thread by Daniel"Malanika"

There will be a sign up list

Since there is not that many

But the beauty of this is that you get to select your handle material and sheath colors that Daniel has available.

Yeah bro
As a knife guy
This is the one to get rather your a collector or a user

Of course I've been seeing great things from Daniels 80crv2 at 62hrc

But This Sprint Run Steel is superior

It will be announced in bout a week

While we're waiting. I would like to know what do the owners of "regular" puukkos thinf of the handle material options? Which are more solid and robust and which are the most pleasant in hand?

Ah, a good way to pass the time

There are three major

Handle materials

Wood
Bark
Micarta




All the woods are stabilized, very hard, impervious to moisture and smooth also very strong.



The Birch bark is the least durable, but is the softest of the three, feels like a very firm cork and indentations can be made with finger nails, currently Daniel doesn't have any Birch Bark
It is warm and beautiful but will require the most care.


The Micarta is the strongest, also has a very slight tactile feel.
It's simply layers of epoxy (glue) and textiles (cloth, burlap, canvas, linen)

My gut tells me CPM M4, but for the sake of variety I'm going to guess Vanadis 4.

Good guesses, Vanadis 4E is very exciting steel

But is just about unavailable

I certainly don't have a source to it

Good thing there is CPM 4V :)

As far as what the steel is on the Puukkos we will know soon enough haha

Hang in there Bros

Hey, if I'm going to be wrong I wanna go down swinging! Someone has to be a bit off the wall ;) Vanadis 4E has been something of interest to me for quite a while. It has been brought up on many forums for many years yet seems fairly elusive. I only have three knives in any steel that Bohler Uddeholm makes, all M390. They all seem to perform exceptionally well and as a third generation powder steel it's a (marginal perhaps) cut above CTS-204 and CTS-20CP.

Upon further Google-fu it looks like at least ZT makes a production blade in Vanadis 4, the 0180 model.

I feel like a may have hit close to the mark with my first guess... CPM 4V then? Also the birch bark handles look AMAZING. I would love to try one.
 
Been waiting for an 80CRV2 with curly birch and missed the one today :(
BUT, Dbh: I am very interested in your project and hope to be in the right place and time when available!
Great idea and great to see your effort in making it happen!
 
What I actually mean is that it would be great if the premium steel puukkos should have a premium handle material as well

Vanadis 4E is a curious steel offering more wear resistance then 3V but less toughness.



Unfortunately Boher Uddelohm hasn't made any effort to make there steel more widely available

( I couldn't find any sources)

But It looks like CPM has picked up the ball and offers CPM 4V(Vanadis 4E) and CPM 20cv (m390) in a variety of sizes at multiple distributors


There's also huge variety of other tool steels that have unique attributes ;)

Can't wait to share :)

Also the birch bark is bomb :)

That was a beauty,



But when these sprint runs become available soon the same knife can be made but in a special steel :D

Click to expand...

Ah I see.

But these are premium materials

You sound like me :)
I always want more, or something special

And heck why not make it your own?

When the sign up list opens


If you get a slot


You can choose from Daniels selection of handle materials

He has some nice burls, Micarta and perhaps birch bark ;)


Hers the best part

You also have the option of buying your own and sending it to Daniel at your cost. But totally worth it to get that custom look.

That's what I chose haha. YOLO



I sent my own material and chose thunderstorm Kevlar :D

Cost me $40 plus shipping



Here is a tease :D




Looks like there is one piece left on AKS









But as long as it's the right size

- 21.5 x 4.4 x 95 mm


the limit is your imagination

Here's some inspiration

A quick Google search for burls will find these ranging from $30-$70










Here my favorite


This would be amazing!!!










Of course these are just embellishments


Just getting on of these Puukos with Daniels handles and a special steel is all one needs
:D
Hope you guys are as excited as I am.

It has to be CPM M4. I guess it COULD be CPM 4V, but the data the OP gives in the video seems to more closely match the heat treating instructions for CPM M4. I mean, he said high speed tool steel, non-stainless, high red-hardness, treated at 2000*F, tempered at around 1000*F with a final hardness around 62rc. To me, that sounds like CPM M4. Very cool project. I'm 90% sure it's CPM M4. The other 10% of me says CPM 4V. Either of those steels should be right at 62-63rc given that heat treatment regimen. I just think "high speed tool steel" more accurately describes CPM M4.

Edit: Oh, and it can't be Vanadis 4, he said American steel. It's something CPM.

Correct the steel is CPM M4!:D



M4 is legendary for its high performance and has dominanted bladesports competitions for the past decade.

Donovan Phillips is the 2016 Bladesports Champion

And he was using a CPM M4 chopper.

It's a proven Steel that hits that sweet spot with high levels of toughness, wear resistance and edge stability, all at the the cost of corrison resistance.

Carbon 1.40
Chromium 4.00
Tungsten 1.40
Molybdenum 5.20
Vanadium 4.00
With some Magenesse And Silicon

Time for some backstory,

I have been wanting this steel in a Puukko for a long time.

All thanks to Spyderco and my awesome experience with my Gayle Bradley which blew me away. :D

But the geometry wasn't suited for woodcraft,
More of a hunter/ utility type and it was a folder, not a fixed blade.


I have been blessed to have someone finally listen to my requests,

Daniel makes some of the most beautiful knives that have great function.

So simple they are just elegant.

Clean lines that create ( what I consider) the apex of function and form for a woodcraft, outdoor knife.

These knives just flow in expert hands, unhindered by modern designs that can cater more to "form" over "function."

Supercharging them with a high end steel is a no brainer haha

[YouTube]3TNt1647Zjw[/YouTube]

The industry standard heat treatment I talked about was a dead giveaway for you steel nerds like myself :D:p


Haha of course this is not the industry spec heat treatment on these knives.

I talked with Brad at Peters Heat Treatment to make sure I got exactly what I wanted.


A Puukko is a wood carving knife first.
Think of it like a super charged scandi but with a stronger edge geometry.

The heat treatment was designed for Maximum edge stability, wear resistance and toughness relative to each other in the highest amounts.

If we increase one of these attributes over the other, it throws off the equation for what a Puukko is made for.

This puts the HRC at 63 with a cryo.

What actually determines these attributes?

It's a careful balance of how many carbides to put into solution,
Martensite to Retained Austenite ratio, grain size, how much tempered martensite, and martensite type.

Which is determined by how long and what heat is used, how fast the blade is cooled and what temperatures the temper is at, and what structures form at what temperature.

Heat treating is a careful dance.

The same steel can be applied to many different knives but with different underlying structures to suit the purpose of the blades intended use all from what heat treatment is used.

"Structure" meets "function"

A M4 Gyuto and a hunting knife would have better performance at 65-66hrc

A M4 bladesports competition chopper would be best at 60-61hrc

And a Puukko 63hrc with M4




M4 offers the highest amount of balance in these areas for what a Puukko is made for, of course at the cost of corrison resistance and (for some) ease of sharpening (which is relative) and of course the cost of materials, time to make, and complex heat treatment.

Also just a disclaimer

I'm obsessed with knife steels and high performance but by no means will I ever turn my nose down at the simple carbon steels or high end stainless.
Understanding, it's just about the right steel for the job and user preference.

Heat treatment, as we learned, is king but there is absolutely no denying that certain steels have intrinsic qualities over others that if applied to the correct heat treatment, geometry, use and preference create a powerful synergy that shows with high performance.

Much to share my friends:)



Special thanks to Danjiel Haramina for making this a reality.

So I was right from the start! I'm guessing my prize will be a free CPM-M4 puukko in birch bark :D
 
Proving that the old Scandinavian straight handle ,barrel shape , is comfortable and efficient . Straight blade is also great .I've been trying to tell you that for years !!!
HT, no mention of eta carbides which you should get with proper cryo HT.? BTW the CPM M4 is the only M4 that should be used for knives . How do I get photo-micrographs of the steel ?? You have to have an independant metallurgist give the OK ! Nice blades -but don't cut yourself ! Make sure you get a signed statement that the knives will never be used for dumb things like cutting bricks !!
 
sign me up!
my favorite steel, a blade design by a maker I have been wanting ever since I saw his first sale post.
This is at the top of my list!

I'm love with Puukkos with a tear drop cross section



It just feels and looks great


eta carbides? Beyond my current knowledge haha

They received a liquid nitrogen quench for 3 hours

Photo micrographs?

I actually saved a blank from the batch for that purpose
But the cost for full testing is $300 to send to metallurgist shop for a report.

My wife said no :D

That's what your for Mete!

Time to break out the your scope and etchant:D

Haha

Signed statement? Hahaha awesome

Good stuff Mete.
:D

Right?! This is the one to get.:D
 
I wonder if 3 hours in LN is enough.
Unfortunately I'm retired so I don't have my equipment or contacts who do. Otherwise I'd do the testing in an instant.
Does he do anything with the birch bark ? Glue , stabilize ,etc ?
That birchwood handle ,to me , is the most appropriate for the knife.
Let's all drool together !
