Gradation 600 is used for proper sharpening and polishing, as well as quick sharpening of slightly dulled cutting edges. The semicircular profile of the stone was developed for sharpening knives and tools with a curved head like karambit, hawkbill, kukri, scythe.
The stone is mounted in an ergonomically shaped polymer case with a brass threaded insert for a guide (not included).
