I had the same opinion previously that SR101 would not be good for choppers. I was wrong. I've been using it for hard chopping and batoning with a 711 on oak and maple hardwoods. It not only chops like crazy, but the edge holds up incredibly well. No chips yet. Cuts through like butter. From my own experience I agree that SR101 is super to SR77 in edge retention. However, SR77 is more rust resistant in a satin finish. Having used both, I'm glad the 1311 is SR101. I would trust me life to either without hesitation.
