We had a workshop yesterday on sharpening. I was surprised at how many folks had some tools that had been mis-sharpened. I feel that some of them can't afford a sharpening system. Does anyone have any links to a homemade simple sharpening system, that might could be build at a workshop session? I'm thinking along the lines of the Wolverine type system, but with fewer adjustments. Key word is simple and I feel from looking at the tools they brought in, free hand is not going to get it. Thanks
