Gradation 120 is used for sharpening severely dulled edges, as well as repairing and bringing out a new cutting edge. 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).
