I have two hones available.
1. This is a Kiita Akasasu Nashiji natural Japanese hone. Kiita is the yellow colouring, Akasasu is the red and the Nashiji is the few spots that are visible on the surface.
This is quite a hard hone, and has a fast cutting speed. I have tested it myself and have sold a few razors that were finished on it and the customers also thought the edge was great. This hone though does not top out the grit scale. It is not the finest there is but is is plenty fine and suitable for razors. I would rate the grit around 1 micron.
The measurments are 17cm long x 5.5cm wide x 2cm thick.
2. This is a Mizu Asagi (water colour blue) natural Japanese hone. It is very hard and quite fine. I would rate the grit above 1 micron. It is also a fast cutting hone for the grit it is.
There is a crack through a portion of the hone but it being lapped doesn't affect the use of the hone.
The hone is quite thick and measures: 20cm long x 9cm wide x 4cm thick. These measurements are the extremes.
The price includes shipping worldwide, that is insured and express.
If you have any questions don't hesitate to ask.
Thanks for looking.
