I used my new lapping plate and I got to say I love this thing. The Button Tech plate from Nano Hone is everything I could have wished for and more. It’s smooth when used and the results speak for themselves. I’ve been using it on my Shapton Glass stones before very use like suggested by @JasonB. I thought that seemed a little excessive at first but I was quickly convinced otherwise. Just a few laps is all it takes when done at this frequency. And the surface of the stone is always crisp and clean which does speed up the grinding process dramatically. Even with the hefty price tag I can say I’m very happy with my decision. But now to my question.... I’m aware that these were made with ceramic stones in mind, but I was thinking. Is there any reason I couldn’t use the Nano Hone on my Naniwa Professional stones? I can’t think of any reason why not. I don’t see this damaging a lapping plate of this quality, especially seeing as it’s made with diamonds. Just thought I throw it out there before I try.
