Cpm cruwear performance.... Wow. I am pleasantly surprised as well as intrigued as to the level of fine "razor" edge retention on this steel. For the ingredient levels in this steel to be lower than other steels, I am perplexed at how it can hold such a fine sharp edge for the length of time that it has. Not saying it is s90v edge retention amazing, just the super sharp edge stays a long time.
I was cutting very thick cardboard to make up some boxes yesterday, and to my suprise after several of these, it still had an aggressive shaving sharp edge. I did bring it to a hair whittling polished yet toothy edge before carrying it. I have a pretty good selection of higher carbide steels, but nothing below m4 since I did not see much use in having a tough steel in a folder. I see that I was wrong, at least in the case of Spyderco's cpm cruwear.. If I had one of the sharpness testing scales, I would run a test with this Para 3.
