Work Sharp Knife & Tool Sharpener electric sharpening machine, WSKTS

This Knife and Tool sharpener does not sharpen any knife or tool I own and the rough edge it achieves doesn't last. I find that the sanding belt wraps around the edge of the knife and therefore will not sharpen any edge properly. There are three sanding belts provided and I used both the 240 grit and 6000 grit and both are useless. 240 grit then all the way to 6000 in one step will never provide an edge that lasts. I want to return this product but I used it so no returns and no refund of my €105.
