Some info:
This waterstone is often called the Chinese 12k (C12k) or The
Peoples Hone of Indeterminate Grit (PHIG), and it is a stone quarried in the
Guangxi province in China. The 12k grit rating is from the Woodcraft catalog,
but that rating has been disputed by many. Some say they are higher, while
others say they are lower, but the consensus seems to be that they are in the
10k to 12k range and are fine finishers.
As
is typical of natural hones, there is some variation of grit range and cutting
characteristics from one stone to another. Some stones are softer and produce a
light slurry with use; they typically cut more quickly, but produce an edge
which is less keen. Some are somewhat scratchy, and may have inclusions which
can interfere with the polishing of the edge. Others however are both hard and
fine. It seems the stones which are gray with dark figuring may be among the
finer finishers.
These
stones are always rather slow cutters, sometimes requiring 100 or so strokes to
finish. This can be sped up by starting with a light slurry and diluting it to
finish with just water.
