Dan has made it clear that we should not expect the 154CM knives to be as tough as their hard-use knives made of SR77, INFI, or SR101. Their warranty is solid, but these stainless Scrappers and Rats are for cutting, not prying. I think the qualities of edge holding and corrosion resistance are what these knives are about. So I would not recommend heavy prying or extreme hard use with them. But it is always comforting to know that the famous Busse warranty is still there if we need it. I hope Dan continues to release both the stainless and tool steel models so we can choose those models that suit our needs and intended uses.
