Sigma Power 13k *PIC*

A fine, soft and slow finishing hone. But it's intended to be fine (grit rating is 0.73 micron and it's a softer feel than the shapton 30 k and may match the latter in actual fineness at the edge. It's certainly going to be more forgiving if a contaminant ends up on the stone).

It's soft enough that if you're not used to using waterstones pull only and slip just a little, it'll gouge deeply.

Slow enough that I'd only consider it for microbevel type work or stepping up the work from a prefinisher/finisher (not from a medium stone over a large surface).

Thirsty and kind of a pain (benefits from a soak, which means planning ahead if used on a larger surface), also - good at what it does but works only in a tiny narrow range. If nothing else, it's a good option to avoid spending what shapton wants for the 30k.

The picture looks great, but don't let it fool you - it takes the stone a minute to create this finish after a prefinish stone on the back of an iron, and that's a solid minute with spraying more water on the surface of the stone. If you had a rigged setup where it would work on a small part of a blade on a pull stroke, it would do nice work.

twice as fine as a shapton cream, but much less usable.
