CPM 10V for a fillet knife???

I process a fair amount of wild game, and a 7" fillet knife is my preferred tool. I'm thinking about trying to make a few fillet knives out of CPM 10V. I'm thinking something in the .050" to .060" range and hardened pretty high. My goal is higher edge retention. Am I going to end up with a blade that's too brittle to bend or fragile to be useful?

Thanks,
Mark
 
Bend is not a factor of brittle, it is a factor of thickness and geometry. Breaking is a factor of brittleness. Tempering will eliminate that pretty well. 10V should eb fine, if not a bit overkill. Have you looked at the stats Larrin has on the new CPMS45VN with nitrogen? Pretty impressive on toughness and retention. It also can be made hard in a fillet or kitchen knife. Only problem is they don't have it in thin stock yet - .10 is about the thinnest so far.
 
I've been looking for a good steel for this project for about a year now. Finding something thin enough has been the biggest challenge. I can't seem to find much of anything less than .125". I'm really not keen on turning half of my material into chips.i know guys seem to like to beat the tar out of their knives, but I don't have any use for anything thicker than .125". For most of my hunting needs, thinner works better. I don't understand why there's not a much bigger selection of the "super steels" in thinner stock. Seems like that would be an excellent application for stuff like 3V, but that's really a different discussion...
 
Based on my experience with a Spyderco K2 in 10V the corrosion resistance leaves much to be desired.
 
Aeb-l will work extremely well for this. Sure it will not have the edge retention of 10v, but at 61-62rc it’ll hold longer than expected and most definitely have an easier edge to maintain.

That's the nice part. Since the are just for me, I don't care much about the finish

z-wear and V4e have exceptional edge holding, and support very fine edges. Not as wear resistant as 10v, but those might be an option to look into. Chuck at AKS has K390 as well, a steel slightly tougher than 10v, but similar to 10v.

Just use the K390 that @Alpha Knife Supply has. They have the stock size you need
 
I have been playing a little bit with 10v and while i think it does have potential I much prefer the X-wear steels and 4v. I have had micro chipping issues with 10v where the other steels have not and 10v can be a pain to sharpen. I have been using a Cruwear knife at 62rc for butchering deer and cutting leg joints and have not been easy with it, the edge has held up surprising well with the abuse i have been throwing at the knife.

We have CPM 10-V in stock at about .055" thick. Call us at 800-424-0048 or email me directly at bob@nsm-ny.com for price and availability.

Can depend also on the HT and how it's sharpened.

I made a 10" gyuto with 10v, works like a champ.

Another steel i have had very good performance with an butchering animals is M4. I just finished butchering 4 deer on my M4 knife and while it is only at 62 rc the edge has lasted very well.

Z-wear (same as cpm cru-wear) has the best fine edge stability of any steel I have ever used. V4e is pretty much the same. I have only made a few in v4e, but the performance is pretty much identical.

Did you try 26c3 at high hardness?

I have a few heat treated, but not finished. I have used hitachi white, blue, W2, AEB-l, z-fiNit, and 52100. These steels are all excellent for fine edge stability, but they cannot match the wear resistance of z-wear, so I give the nod to z-wear. I haven’t made a z-wear knife with larger than 0.005” edge before sharpening, or under Rc63 in two years now. I’m sure 26c3 will be excellent too, based on chemistry, and Larrin’s testing.
 
The best fine edge stability steel's true test is a razor blade geometry imo. I'm curious to see how z-wear would do because carbide steels rarely do well in that department. The matrix may have issues holding the carbides in places in such fine and steep edges.

that's weird because I have the same knife and it’s been fantastic, not a spot on it. I used it to open salt bags every day for almost 3 years when I ran a boiler. As for hard to sharpen I have not found it that difacult. Using a 1200 grit diamond stone it only takes a few min. I only have to sharpen it a few times a year but it’s my daily carry.
