As a basic equipment, a combination stone with 1000 and 6000 grit is sufficient (No. 711006). For more demanding tasks, stones with 220 grit (No. 711010), 2000 grit (No. 710991) and 4000 grit (No. 711021) as well as a very fine 8000 grit polishing stone (No. 711004) are recommended. A cleaning stone »Nagura« (No. 711302) can be used to produce a polishing paste.
During use, waterstones must remain rigid and not-slip. To ensure stability, use a sharpening stone holder with non-slip rubber jaws (No. 711101), a rubber underlay, or a non-skid mat (No. 705364).
