SHIRO SUITA AWASEDO

193 - 70 - 20mm

.67 kg. = 1.4 lbs.

Reads at the top left SUITA (the strata level)

And in the middle TOKUSEN (best quality).

This stone matches up with Suita #218 which has a paper label that reads: TOKUSAN (special) below that KOZANMOTO (Kozanmoto Mining Co.) down the center SHO HONYAMA NARUTAKI AWASEDO (true original mountain Narutaki finishing stone).

Most of these mining companies do not exist anymore or have developed other products. Also look at Suita #206 and you will see another stone by this same miner.

A truly interesting stone of diminutive size with an amazing amount of rich renge particles. This is a fairly soft stone with enormous cutting strength and speed and a very fine grit particle. The stone has so much renge in the purple form that the stone has a purple glow to it. This stone could be used for harder steels like blue steels also.
