Query: This will ruin your knives.

I have a LOT of knives. I like to keep them pretty sharp, and for my standards they were all getting a little dull. The AccuSharp had such GREAT reviews on Amazon that I thought why not try it?I tried this thing on about 5 knives. It made them SO much duller than they were before. This this is GARBAGE. I have trouble even giving it one star.This thing takes off a lot of metal. It literally ruins your knives. If you value your knives, stay away from this. Go get the Spyderco Tri-angle Sharpener. After about an hour with the Spyderco, I've gotten my two favorite knives back to RAZOR sharpness.Seriously. AccuSharp is the worst thing you can buy if you want sharp knives.
