I have a DMT Extra Coarse plate that I use for flattening stones. Is it worth the money to pick up the Extra Extra Coarse stone and use that instead?
I have a gift certificate for Lee Valley here where I live (Atoma 140 is not an option).
I am also picking up a Sigma Power Select II 13K stone. If if I don't need the DMT XXC, I could instead get yet another stone from Lee Valley.
Thanks a lot
