The DMT sharpeners are excellent diamond sharpeners. The base is also a valuable piece of lightweight plastic. Every base accepts both sizes so you only need one, even if you are using both the 8" and the 10" sharpeners. Each stone has two sides with different grits. We recommend the Coarse/Fine.

"With exception you will get what you pay for. If you want the best you should buy a DMT stone because of the results you will get. Why buy a cheap stone when you can spend a little more and get the best. We have used many different stones with decent results, but until we used DMT stones we didn't know what a sharp knife was." -Bob Dozier
