To whom it may concern, I got my DMT Aligner Kit today and I just cant say enough about it and my experience with sharpeningsupplies.com. I got the extra extra fine stone along with the DMT deluxe aligner kit. My favorite knife now is as sharp as a scalpel. First Class Company and First Class Products. Truly a pleasure doing business with you.
