This stone worked well for its job. I used it on my knives, and it sharpened them as well as a medium stone would.

I sculpt in concrete. Use various size Dremel grinding bits for finishing. I wish the bit was a little sturdier as I go through them fairly fast. Everything Dremel is excellent quality.

It wears down pretty fast. Still better than a file.

works well, quickly
Just sharpened the lawnmower for the first time this season, with the sharpener guide attachment, it had a sharp edge in 2 minutes. Burrs gone, perfect angle. So much easier than taking the blade off and trying to use a grinding wheel.
