The Work Sharp Pocket-Knife Sharpener puts a mean edge on knives quickly, and is small enough to take into the field. All elements are self-contained, so theres no set up or pieces to lose. This pocket-knife sharpener features two sharpening surfaces: 320-grit diamond plate with a 20 angle guide; and a fine ceramic rod with a 25 angle guide. The sharpener stands on its own, and the practical design keeps fingers away from the knife blade during use. Cancer and Reproductive Harm- www.P65Warnings.ca.gov. Type: Sharpeners.
