So I bought a spyderco sharpmaker a number of years ago and I'm pretty much unhappy with it. I've worked my endura wave on it enough that it can be sharpened fairly well on it now. When it comes to other knives though its just too frustrating. It offers choices of 15 or 20 degree angles but the brown stone just isn't very rough and if you're trying to reprofile a knife to 15 or 20 degrees... eventually just give up. Anyone else have one? Any tips on how to take something like a kitchen knife and make it not suck with the sharpmaker? Should I have bought the lansky?
