SHIRO SUITA AWASEDO #56 with Renge & Nashiji

210 - 85 - 62mm

2.75 kg. = 6 lbs.

From the top right in smaller kanji GOKUJO (extremely fine quality)

Reads on the stone top from the upper left down in kanji in larger letters HON SUITA (original mountain suita strata stone).

And down the middle right BIWA as in lake Biwa

To the lower left SAIKOKYU (very best quality)

A very large wide and very thick stone with Renge on the top surface and Nashiji on the back surface of the stone. The back has been flattened with a diamond plate so it is useable just like the front is. This may be the most unique and incredible stone in my Suita Shop. These white stones are rare enough but with the attributes of this stone, it is special. This is a true deep strata Shiro Hon Suita stone.

It came from a store in a small town in Japan that closed in the 1970s containing stock dating back to the 1930s. The awasedo has not been used other than to test the quality at one edge of the stone as you can see in the photos and it is considered to be New/Old Stock. This is a genuine early 20th century awasedo from the pre-war 1930s era.

The stone is very hard and cuts fast on both the front and back as you can see in the close up photo. The metal is cut without creating any paste if you begin with just water. Because these stones are so hard, I found that they are easier to use if you use a diamond plate as a "diamond nagura" to first build up a paste as you can also also see in the photos. The dried paste from the diamond nagura is a pure white as snow even the back of the stone.

This stone front has a grit of 38,000 or greater when the particles in the slurry are ground even further as the paste forms and develops and the back is even finer into the low 40,000 range.   

*If a diamond plate induced slurry is used.
