Available in three grits: fine, medium, and ultra-fine. Flat and broad ceramic stone, highly effective for honing wide tools like plane irons, chisels and large blades. Use dry, no oils or water needed. Packaged in a polymer case with non-skid feet for tabletop use. DoubleStuff consists of medium and fine grit stones, sandwiched together with a bonding agent. Because Spyderco's benchstones are flat and broad they are highly effective for honing wide tools like plane irons, chisels, large blades, woodworking equipment, even ski edges.
