Works similar to the Jool Tool (which I LUV for turning tools). You free hand sharpen. The base unit needs to be near the edge of your bench so that you can get up under the disc. I don't have any place to anchor my hands like on the Jool Tool. Disc is much larger than the Jool Tool which is very nice. I don't have the range of grits than the Jool Tool, but for turning tools, this is not a major problem, but I tend to polish down to 1-3 micron on my turning tools.
Not quite sure whether I like it or not. I sharpened a plane blade on the Tormek, then took it over to the Work Sharp for a comparison. Took a LOT longer to sharpen on the Work Sharp. This is because either the Tormek's jig was not 90 degrees true to the stone, or the Work Sharp's blade holder wasn't true. So I essentially had to regrind a totally new bevel. Took nearly a hour to regrind and work thru all the grits. Made quite a dusty mess.
