I’ve purchased a 400 grit stone and a Tsushima stone. After 25 years of working with Japanese tools I’ve found the best stones available. The 400 grit is a must have !

Bought this stone to both refurbish old tools and to take out any nicks in a blade. I have to say this is one of he fastest sharpening materials I have ever used and that includes diamond plates!! I'm not a fan of the skidding feeling you get with a diamond plate. The feeling of this 400 stone is very tactile and suits the hard Japanese steels. Be careful though the steel disappears fast! The very attribute that makes this stone so fast at cutting is also it's only disadvantage....It wears quite quickly (as do most big grit stones). Regular dressing is required and if you do a lot of sharpening I would recommend buying 2x. It's a small negative for a very good stone though.

Excellent stone for what it is - very consistent particle size and soft enough for major repairs of those super hard steels. Nicely done. Thank you.
