I read a lot of good comments on our forum about the Work Sharp knife sharpener. I paid close attention to the comments about how the Ken Onion Edition is basically a gussied up version of the standard sharpener, for double the price. The point being the Ken Onion doesn't do anything that the standard Work Sharp doesn't do.
I found my Work Sharp WSKTS Original Knife and Tool Sharpener on ebay, NIB with all accessories and papers, $63 with free shipping. I thought this was a great deal and jumped right on it. The brown truck brought it the other day, it had the 220grit belt on it which was just fine to start with. I found the tool easy to run, easy to learn how to move the blade across the belt, and I got my best results using the side of the belt that cuts from edge to back, rather than the side that went downhill and cut from the back of the edge. This requires spinning the unit around every time I switched sides of the blade, took a little bit of extra effort, but once i saw how nice it was working, I think I will keep using it like this.
It took about 3-4 passes on each side of all the knives I sharpened with it, to remove the jagged mess left by countless passes of the carbide "V" type pull-through sharpeners that I have used over the years. It should only take a minimal amount of work to sharpen the edge the Work Sharp created.
