An easy to use knife sharpening jig. Set the angle, hone 1 side, flip the blade in seconds then hone the other side. Comes with 4 stones to get the blade very sharp (120 - 320 - 600 - 1500 grit). Brand New I purchased a few extra items which I use with my sharpener and are available to add to this sharpening jig: $2.50 - 60 grit (if you have lots of metal to remove) $4.00 - leather strop
