I recently placed my first order after finding you on the web while looking for grinding wheels. I am a customer for life. Here's why. My first order was a simple white grinding wheel for a "normal joe's shop". When I received the wrong wheel (150 grit instead of the ordered 100 grit) I called and without hesitation or the 3rd degree another wheel was sent off. No questioning of my integrity, intelligence or honor. Simply "I am sorry, we'll send the correct wheel off immediately..." The right thing was done by a neat guy. I was treated like an adult.

All my sharpening orders, albeit small shop orders, will now be with you. Promote you I will.
