Lots of metal buildup on the stones?
I have something happening and I'm not sure if it's normal or not. Nearly as soon as I start sharpening (from a clean, soaked, and lapped stone) ... the entire stone turns gray (I assume from the metal of the knife) and quickly builds up so thick that I need to wipe it off the knife like "mud." My quick, this happens within a minute from starting. Is this normal? Am I doing something wrong?
Oh, and the knifes I'm using are two different Misono UX10s.
