CPM S9V looks amazing. Probably hard to work and hard to sharpen, but once it is there... <img src="/ubbthreads/images/graemlins/smile.gif" alt="" /> Check out how it compares to M4 in wear resistance and toughness. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />

CPM S9V


I have no interest in CPM S9V for a knife.

While S9V ranks up in the S7 ranges for toughness, it is designed to be hardened at a pretty low hardness range (like S7). So, while S9V can be made VERY tough, it isn't likely to get or hold an edge very well.

.

KG- Why do you say this? According to the graphs on the page I supplied the link to, CPM S9V has a higher wear resistance than S7, A2, D2, M7 and S3V (and is tougher than all of these with the exception of S-7 & S3V). Doesn't that equate to edge holding ability? Like CPM S30V and S90V have very good/high wear resistance which I thought equates to edge holding ability - i.e. the edge won't wear as quickly...? Maybe I'm not seeing this correctly? Please explain if you would...Thanks. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
