The Kasumi 80001 combination whetstone with rough (240) and medium (1000) grit.

If your knife edge is in poor condition, start sharpening with the rough # 240 grit of the whetstone.

If your knife is in average condition, start with the # 1000 medium grit of the whetstone.

These two grits will keep your knives sharp enough for normal home use.

The whetstone comes with a hard rubber base for use when sharpening.

There is also a small abrasive stone to be used to grind the surface of the stone.
