Makes Short Work of Sharpening

I got the coarse/x-fine combo because I needed the coarse side for cleaning up the stones I have, and the x-fine side for further honing after my 600-grit stone. Definitely worth it, and the large size makes it easy to handle chsiels, plane blades, other stones, and so forth.^M

Diamond stones cut a lot faster than oilstones, and the extra fine side puts an excellent edge on my planer and chisels. After flattening other stones, I used the coarse side to quickly lap the back of a couple blades I am tuning. Pricey for a sharpening stone, but they really work great.
