Description
The smaller format of this series makes it ideal for freehand honing of the longer edges found in most households (knives, shears, scissors) or smaller edge tools such as carving or turning tools.
The stones are 160mm × 37mm (6 5/16" × 1 7/16"), weigh about 180g (6.4 oz) each and are 12mm thick, about 7mm of which is usable abrasive.
