CPM4V love?

I was given some of this steel and decided to make a personal Combat/Utility to try it out. Had it hardened to 62. This stuff takes an amazing CLEAN edge.

From what I've experienced, it's pretty good stuff. It's a well balanced steel all around if corrosion resistance isn't your top priority.

I used a fixed blade in 4V on a demolition job to cut carpet, pry off baseboard, cut holes in drywall, etc. The edge stayed sharp for quite some time compared to the S35VN and N690 blades I used for the same tasks. Also, after all the prying I put it through, I never broke the tip.

Edit: Forgot to say good job on that fixed blade Brother! Your work is starting to have its own distinct style:thumbup:

I have a couple of blades in 4V, including the latest spyderco mule. I like it a lot.
And really nice design on yours, CM!

Never tried that steel before, but like the others, I like the overall shape/design of this one!

From the little that I have read, the stuff is like 3V but better.

I have wanted to try this steel. I have been using 3V and Z wear in several folders and a few fixed blades, but everything I read is this steel will smash 3V on edge holding. Waiting for AKS to get more in a thicker size.

Just ordered a couple of bars from Niagara in 3/16. I believe they had thicker than that but don't quote me on it.

I only have a Mule in this steel, and haven't had the chance to try it yet, but will this weekend!

I haven't tried it myself, but have only heard good things about it.
Nice blade, boyo. Looks good.

Figured I better update this thread... The tanto belongs to Clinto.

From the little that I have read, the stuff is like 3V but better.

4V is more wear resistance and has capability to be heat treat to higher HRC. 3V is less prone to chipping, can take higher lateral load before catastrophe failure at same hardness and noticeable more corrosion resistance.

Dan Keffeler who work also with Vanadis4E (alloy close to 4V with a bit higher Mo and more advance PM process) use 3V for his katana and V4E for his smaller blade.

So which steel better is depend on your goal.

Corrosion resistance is a big plus.
