Whomever first suggested using a sharpie on the edges...

Thanks. It is a great tool. It's helping me in knowing if I'm really sharpening how I should. Also it's letting me know if my edge is the correct angle. If I'm on 20 degrees on my sharpmaker and I know I'm holding it right and I'm not removing the ink I probably need some re-profiling.

THANKS.
