I just recently purchased a Bulldog Large Congress and it is giving me a fit. No matter what I do it will just not take an edge. It is the stainless steel, and I know it won't sharpen like carbon will, but this thing is just plain dull. I've tried sharpening it on every type of stone I have and when I'm done it's about as sharp as a butter knife dragged over a brick. Never had this problem with any other knife I've ever owned. Is this common with Bulldog knives?
