i have used CPM S30V on a pair of kitchen knives. I used peters heat treat and went to 61HRC. I was a really impressed with how they held up. I had one come back for sharpening after over a year of use. Not too tough to work with. Easier than the kitchen knife i made in CPM 20CV. But the 20CV holds a razor edge much longer at the same hardness.
My first benchade has S30V and i did like it. Back then i had kind of a tough time sharpening it, but i got pretty good at it and got a mirror polished edge eventually. I did go from sharp to dull one-time xutting carboard at a job i worked at. I cut a lot of cardboard that day, it dulled enough that i had to switch knives because it went totally dull. But i did and impressive amount of cardboard.
I will admit that im a total steel snob. I typically work with CPM 3V, 20CV, Z-Finit, Z-Wear, CPM 154. I have used CPM 4V and plan on trying, CPM M4, CPM Rex T15 and Vanax eventually. But having used S30V in my own knives i was impressed with how it held up at 61HRC. Peters has an exellent heat treat recipie for it.
How do you like spydercos CPM M4? Ive never used it and been itching to try it out. Same with their Cru-Wear. But im not paying 300 bucks for a cruwear para 3 from bento box.
