Hoffman,
I, too, have a BK swivel knife which I am not fond of. But, you invested, so you are probably going to try to make it work for you. Given that, all I can say is to sharpen the hell out of it, then sharpen it some more (jewelers' rouge), and then strop it every time it starts to drag. I found a GREAT swivel knife from Henley, back in PA. Of course it still needs an occasional stropping, but I can go a long way between sharpenings. If you need the contact info and pricing, let me know and I'll go look up the paperwork.
