Review on HTS 131A0 Dual Diamond Sharpening by Joe Griggs

I've used this thing quite a lot. I sharpened the dresser knives using a manufactured jig. I thinned shims to make spacers for my planing tables. I used it to sharpen turning tools. Just wash it with soapy water and wipe dry. The thing seems indestructible when it comes to sharpening with it. My only complaint is that, as far as I can tell, finer grades are not available in this style. I have also found this device to be good for leveling guitar frets.
