NEW! The AccuSharp Tri-Stone Knife Sharpening System allows you to easily sharpen and hone any straight-edge blade with ease. AccuSharp’s three stone surfaces include coarse diamond, medium alumina-oxide, and fine ceramic. This Tri-Stone System provides extra durability and safety on any surface with a rubber-grip base which prevents sliding while sharpening and honing your knives. Additionally, the Tri-Stone Sharpener base can be mounted to most countertops for extra stability. Also included is an angle guide to assist in maintaining a consistent angle while sharpening.
