Support BladeForums! Paid memberships don't see ads! I think Scott has worked pretty extensively with both CPM 154 and S35VN. I’m wondering which of these has more desirable traits for a 4” or so knife like the Polaris. I would imagine CPM 154 to be a bit more damage resistant and easier to resharpen. S35VN seems like it would be more abrasion resistant and hold an edge longer, but at the potential cost of some chipping. This is all theoretical for me. I have one blade in this size in CPM 154, but have not found any use for it yet. I have a lot of experience with 154 CM and S30V, but I don’t think that is very relevant to their newer versions.
