- Superfine grits for absolute mirror finishes and ultra sharp edges
- Can be left dry when not in use
These are superfine grits, the stones are used to bring the metal to an absolute mirror finish, and hence an ultra sharp edge. Whereas the coarser stones can be stored in water, these super fine stones are harder and not so porous, so only need to be sprinkled with water just before use, and left dry at all other times. They are mounted on bases and the very finest are supplied with an artificial Nagura stone; used to de-glaze, true and build up slurry on the surface of the stone, which helps the polishing process. good choice for everyday work.
