I saw the Work Sharp Knife & Tool Sharpener advertised on one of the hunting shows recently. It's basically a small, portable belt sander that has guides for knife sharpening. I decided to buy one and I've been very impressed with it. I've sharpened a bunch of old knives that I couldn't get an edge on. I've sharpened my axes, machetes, and a bunch of other stuff that I use around our property. I haven't seen anyone on here talking about these so I thought I'd check to see if anyone else has gotten one and, if so, how they like it.
