Works well
This thing does what it is supposed to do, and at far less cost than some other models. Also, I really like that NO skill is required to use it, unlike a sharpening steel or whetstone. I use it on hunting knives, fillet knives, "junk" knives that we use in the garden or while fishing, and on all of our various kitchen knifes. When you're butchering a deer and your knife gets dull every few minutes, this model is hard to beat: a few passes through each side (coarse/fine) and you're finished. The only downside, as at least one other reviewer has noticed, is that you can't sharpen all the way to the end of the blade (the part closest to your hand). But not much getting gets done there anyway, so that's a minor issue in my view. Eventually, it will wear out, and you will realize this when it no longer is effective (doh!). A worn-out sharpener can also be seen, i.e., if you notice that the rods are in the shape of a "U" with a rounded bottom instead of nice sharp "V", it is probably time to get a new one. If you have a big knife like a Kabar and put too much force on it, it is possible to break the rods, but if you do it's your own fault. Don't ask me how I know this...
