Two Grits On One Ceramic Pocket Stone.
The same ceramic material as Spyderco's famous Triangular Rods, the Double Stuff combines both the medium and fine ceramic grits on one stone. Providing fast and complete sharpening in a convenient, portable package, it even comes with a leather pouch for storage.
The Spyderco stones are finer than many other manufacturer's stones with similar names. So the Spyderco medium is comparable to what other brands call a fine, and the Spyderco fine is comparable to what other brands call an extra-fine. The ceramic sharpening surface is very hard and durable. These ceramic stones are to be used dry (no oil or water). Cleaning is easy, just use a plastic abrasive pad and powdered abrasive cleanser. Stone measures 5" x 1" x 1/4".
