Mensuri lapping stone 262x115x15mm

I've spoted this lapping plate fist on youtube. I contacted my supplier in Japan, and he found this lapping plate for me. The name of this product is Mensuri.

They were manufacturing 2 sizes, 262x115x15mm and 330x130x30mm. However the larger size was discontinued. Since my stone collection growing and growing, and I am using stones for razors and Japanese knifes as well, I am sure I need one.

Why is it better than say a DMT325 grit?

IMO this is better than DMT because lapping surface is bigger. With powder, out of the same plate I can get different coarseness, most likely “coarse” and “fine” (I haven’t checked exact “gritness” yet, but I will in about 2 weeks), it will never rust, for the really hard stones like Shapton’s, DMT might not work that good because of small size and lack of “free” powder, and it is similar what Shapton offers for it’s own stones for half the price.

I am honing my Japanese knifes once a month, rotation razors and kamisori about once a year. I have 5 Shaptons made for the Japanese market, 4 J-nats, 4 other naturals, and some synthetic stones, for all that, DMT 325 become DMT 800 in no time :D

Any developments with this?

one thing to keep in ind is it will also need lapping from time to time.
The powdered grits i believe are up to 220 but might be wrong, it should work great on synthetics, but I personally would never put a natural to it.

I made a special arrangement with a german car manufacturer concerning the production of super flat high durability stainless steel referencing plates.
Since it takes six hours to cut in the grooves and make it flat (like I said, it´s a tough steel) these are not a cheap option but it certainly does work.
The one shown in the Video of mine has been used for about a year without any signs of wear. I check it regularly.
Sharpening stones usually are (bonded) softer than we think

Unfortunately no. It will cost me fortune to ship it from Japan. I gave up on this.
