Brand: Komon-picked Imanishi
Producing Area: Kyoto - Japan
Strata: Suita
Appearance: Stunning white and light-gray surface with some small Aka Renge. A large number of visible Su. Some, only one can be very faintly felt but has no negative effects.
Size: 212mm x 80mm x 40mm
Weight: 1614g
~Grit Range: 4000-6000+

1-5 Scale: 1 = Less, 5 = More
Hardness Level: 2.5
Scratch Depth: 2
Speed: 4
Wear Rate: 2
Self Slurry: 3.5
Thirst: 2.5
Consistency: 4
Feedback: 2
Ease of Use: 4

Notes: A beautiful stone both aesthetically and for polishing results - great coloring effects, leaves a soft transition at the cladding line. A very consistent, easy to use, and very, very fast stone. A very fine black slurry forms pretty much immediately, and a gray slurry when working the whitter spots, and working the slurry further creates an incredibly smooth feedback. Scratches are incredibly uniform and pretty shallow. You could finish on this for a frosty kasumi, or has a really fast pre polisher for something brighter. Pretty much an ideal stone for wide bevels. It feels almost pillowy-soft and has a slightly chalky feedback almost akin to working a Nagura, in fact you could largely substitute one for another. Given its ease of use intermediate users could quickly benefit, but you would certainly find this in a professional polishers arsenal.

Recommended Usage: Pre-polishing, final polish, super refined edges. Could be used for push cuts if used with light pressure.

They are also very beautiful.
