hello, my name is josh and im new to knife making. i havent got any tools yet but plan to get some soon, but first i need to sort out a few things. My main one right now is what are some good steels for small and medium utility/camp knives and maybe tactical ones too. im lookign at crucible website and under knife steels there's. 440C, 154 CM, CPM S30V, CPM S90V,CPM 3V CPM 10V, A2, D2, Rex M2.... the one i like most from just reading is the cpm 3v but im not expert. so basically my question is what are some good steel for my purpose. also do most steel's heat treat the same or do i have to do each differently?? thanks.
