I have both 154cm and s30v knives.
After I reread your quote last night, I went and researched the difference. I was going to post here, with the difference(s) and a link to another thread here on bladeforums that explained everything very clearly. However, since the thread's original question was 154cm vs s30v, not CPM154 vs s30v I thought it would be offtopic.CPM154 and 154CM are different things.
