The Original Work Sharp Knife & Tool Sharpener is the first knife sharpener designed to sharpen every knife you own. Using flexible abrasive belts, the sharpener is able to sharpen not just straight bladed knives, but also curved knives, tanto blades, filet knives, serrated knives, gut hooks and virtually any other shape of knife blade. The Knife & Tool Sharpener uses precision angle sharpening guides to ensure that you get the proper angle every time. Two guides are included: a 50° guide for hunting and outdoor knives (25° per bevel) and a 40° guide for thinner blades and kitchen knives (20° per bevel). Professional knife makers use flexible belts to put a razor sharp edge on their blades, and now you can have the same technology at home to use any time your knivesget dull. You may already have other sharpening methods, but never before has a knife sharpener been able to quickly and easily sharpen this broad range of knives to such extremely sharp results. This tool is assembled and quality tested in Ashland Oregon and has a 1 year warranty. Includes a detailed User's Guide and Instructional DVD.
