Review on ✨ Coarse Grade Atoma Diamond Sharpener #140 by Centerfold Montague

I bought 140 grit and am completely satisfied with the stone. I sharpen carpenters planes and chisels on Shapton Professional and Glass stones. I needed a good rough diamond stone of sufficient size to smooth my <1000 grit stones. I considered others but this purchase was not a mistake. It smoothes out very quickly (faster than a Shapton diamond bur) and shows no signs of wear. Atom is a very high quality stone. This particular rough stone is a bit rougher than what I usually need for sharpening, but I imagine the larger Atoma stones would work just fine. I am totally amazed at the speed at which this stone cuts when leveling.
