As some here are aware, one of the major producers of synthetic whetstones in Japan has been working on their version of a super vitrified stone for some time. A few examples of their prototype is starting to make the rounds and they sent this to me to try out and give feedback. It is a solid, homogenous, 20mm stone, in the same sense as a classic AlOx water stone.
One of the, maybe, unique features of diamond grit is that smaller grits tend to cut faster than larger grits. Same concept as the tip of a nail cutting better than a head of a nail, even though they are both a single point. Secondarily, fewer “points” can cut faster than many points. Using the analogy of nails again, a bed of nails can support a man laying on them, but a single nail, or 10, would penetrate.
This is supposed to be a 1K stone that can replace ((almost)) every stone of lower grit…..
