Japanese Waterstones
The Japanese traditionally used sharpening stones lubricated with water (using oil on a waterstone reduces its effectiveness). They have been doing this for many hundreds of years, and the first stones were naturally occurring. The geology of Japan provided a type of stone which consists of fine silicate particles in a clay matrix. This is somewhat softer than Novaculite.
Japanese stones are also sedimentary. The most famous are typically mined in the Narutaki District just north of Kyoto.

Famous quotes containing the word japanese:
“A pragmatic race, the Japanese appear to have decided long ago that the only reason for drinking alcohol is to become intoxicated and therefore drink only when they wish to be drunk.
So I went out into the night and the neon and let the crowd pull me along, walking blind, willing myself to be just a segment of that mass organism, just one more drifting chip of consciousness under the geodesics.”
—William Gibson (b. 1948)
