Boron Carbide Abrasive—Harder than standard abrasives such as silicon carbide and aluminum oxide, boron carbide will hone hardened steel, titanium, and iron. It's not as hard as diamond, however, so it can't hone carbide or ceramic.

Twisted Shank—Snip the shank to shorten the length of your cylinder hone.

Grit—Grit is identified by the color on the tip, except 120-grit hones are unmarked.
