My Classic Carbon Folding Hunter has been holding a pretty decent edge in the three months I've had it. Provided, I only use large folders on heavy materials and for big jobs, so I cut some materials that quickly dull a blade often. I did touch it up once a couple days ago and it took no effort to get a razor's edge back on it. IT doesn't really hold an edge as well as the 50 year old Case it replaced, however. It, so far, seems to be an incredibly great value for the $15 (direct from SMKW) I have in it. Next time, one of the ones I'll order will be a Sodbuster Work Knife in carbon steel. The 440A version is my favorite RR, and actually one of my favorite knives period.
