If you grind your Japanese chisel on loose diamonds will the diamonds imbed themselves in the softer iron part of the chisel. When you then go to higher grit loose diamonds, or paste, diamond against diamond will knock the lower grit out and it becomes a wild grit. I can't think of a reason that this would not happen. Also if you went from diamonds to a natural stone the imbedded diamonds would do a job on you stone. Can you tell me about that scenario?
