Yes they do harden the lock bar face. I forgot the term used (carbonize ?). The biggest things that seperate the Sebbie from other knives are the tight tolerences and the pivot bushing. CRK is constantly upgrading their folders. When the Sebenza 1st came out there was no pocket clip. Then they added one and a few yrs later pt an extra bend in the clip. Now its one of the best clips on the market. The Sebenza started with ATS-34 steel, then BG-42, and now S30v.Does anyone know if he hardens the lock bar face or puts some type of coating on it to reduce wear?
What I would like to see is a more user friendly thumb stud. I would also like to see a different finish on the handles. Something that does'nt scratch so easily.
