Atoma Diamond 4" x 1"

Would like to see better description in Gritomatic’s advertisement regarding this stone. You can not get a consistent angle with this stone on the KME unless you use all Atoma stones or purchase a stone compensator or angle guide. If you use this stone plus any other KME stone with it, your angle will be different because the Atoma stone is thicker than KME stones. I know Gritomatic’s website states it is compatible with the KME, but like I said, only if you use all Atoma stones or buy a stone compensator or angle guide. Do not use 1 Atoma and the rest KME stones. I’ve had detailed discussions with Gritomatic regarding misleading advertisement practices, but they are unwilling to address this issue at this time. As for the stone itself, the 140 is extremely aggressive, more so than KME’s Beast. It works super fast for reprofiling but removes a ton of metal in a very short time even with very light strokes. I would only use it if you have to remove a lot of steel to get your desired angle. But for doing that, it gets an A+

4" stones are a good value, but I like the 6" stone holder/adapter much better! These 4" stones are fine for what they do: sharpening smaller knives with a steep angle. The stones are fine for the money. But, if you are thinking of an upgrade for the Worksharp Precision Adjust system, I would highly recommend skipping the 4" stones altogether and going to the 6" adapter made by Gritomatic. I've found the 6" size to be much more versatile and less prone to dragging on the clamp.

Cuts great and uniform Does exactly what you need it to. No issue with high speed steels.
