So I'm about to get my first blade in CPM 10V, and I really don't know very much about it. I understand that it's similar to S90V, only less corrosion resistant and even better at holding an edge.

If anyone has any experience with this steel, please weigh in. How big of an issue is corrosion? How intense is the sharpening? This is one of the few links I could find: http://www.bladeforums.com/forums/showthread.php?t=483828

Any information and experience with this steel would be much appreciated. :thumbup:
 
these are fairly rare in hands of consumers. just clean blade after use & as mentioned a tuff cloth or a little remoil. i would imagine if the heattreat is good it will cut up there with top 3% of knives in production.

It's a Snody, which means HT'd by Bos. I think it'll be acceptable :D I'm real excited to see what this steel can do. It's a 1/4" thick slab of 10V, so I'm pretty convinced it's going to be damn near indestructible.

Anyone ever sharpened this stuff before? How much of a bear was it?

You might want to try this question in the Makers forum, they will know a bit more over there.

The edge holding is slightly better than S90V but sharpening 10V is a real nightmare. IMO its not worth going with.

I would stick with S90V, its stainless and it's slightly easier to sharpen with almost as good edge retention.

I have a CPM 10V from Phil Wilson, and did post some comments and reviews, but it was about 5 years ago, I'm surprised that you couldn't find it.

It's my best edge holder. Phil hardened it to 64.5 at my request, at the risk of being on the edge of toughness, but this really enhances it's edge holding. I'm not going to be batonning or cutting wood, just animals. I've tested the edge cutting rope and cardboard, and it is really spectacular. The only knives that I have that come close are in M2 HSS at 65-66 HRC. Everything else is MUCH lower in terms of edge holding.

It might be hard to sharpen if made like any other knife, but with this steel, Phil really optimized the geometry for cutting to take advantage of the steel, which is exactly what I wanted. It is a very thin full flat grind. I can completely reset the edge in 5-10 strokes on a dmt blue. Sharpening is about 30 seconds, and that's from "won't shave arm hair dull" to very, very sharp.

It's a fantastic steel, no corrosion issues yet (I live in a dry climate), but it's a specialist. It's very good at one thing, so understand that before you buy it.
 
I have experience with cpm 10v, very similar to that of Sodak's. Phil Wilson's knife, 64HRC.
Edge holding is very high, and with proper tools and some experience, it's not that difficult to sharpen.
The only time I use diamond stones is when I need to change the bevel angle, for the routine maintenance microabrasives(0.25mic and 0,50mic) and various whetsones, depending on the edge wear.
Like Sodak said, this isn't the steel to baton wood with, but for light and medium cutting is is very capable. Besides the rope and cardboard I've cut wiring, done some wood whittling, etc, the knife held up just fine. Details in the Phil Wilson CPM 10V knife review.
 
Phil Wilson does everything to get the maximum out of a steel that you can get, from the blade grind optimized for cutting to the HT and tempering to get the best edge retention possible while still being tough.
 
Thanks for the info and links! I'm not too worried about edge holding and wear resistance with 10V, it sounds like a monster in that regard. But how's the toughness? The posts above me make the steel sound like it's not very tough. I assumed it would be very good with toughness as well due to the high level of carbon. The blade I'm getting is .25" thick with no fine point, so I'm suspecting it's going to be near indestructible. Correct me if I'm wrong please.

Here's a link that makes it sound like it wouldn't be a problem for batoning or anything heavy duty.
 
Where's the link? IMHO, CPM 10V would be wasted potential in large, heavy duty blades.
0.25 thick at 64 hrc can still snap in large knife, when used for chopping or prying.

Toughness is relatively low on 10V. Check out some threads on 3V. 3V will give you unreal toughness, with excellent edge retention (although edge retention is not in the same league as 10V). M4 gives a good mix of edge retention and toughness.

It sounds like you want a big blade. 3V or M4 might be better for a big blade IMO.
 
ditto to jaymeister & gator. even a diamond can snap with enough shock. i agree with sodak that it's a great cutter but no camp knife.
