I bought this stone because I like the 400 grit Naniwa Pro Diamond so much. A typical progression is 400, 1,000 and 5,000 grit to finish. I also finish many knives on this stone. I have sharpened at least 100 knives now on this stone and it’s quite good, it exceeds my expectations. Diamond stones are very popular now in Japan and growing in popularity elsewhere. I can see why now and I have no hesitation in recommending this 1,000 grit stone. It’s feels wonderful and thus far has not dished at all, no sign of wear whatsoever. You’ll love it.
