The Work Sharp Guided Sharpening System is a complete sharpening solution for every knife you own. It features the innovative Pivot-Response System which allows the abrasive to follow the curve of the knife while sharpening - making manual sharpening faster, easier and more precise than ever. The Pivot-Response can also be locked out for traditional manual sharpening, creating the ideal sharpener for both the novice and expert alike. The system includes an Angle-Guided Bench Sharpener with 17Degree & 20Degree angle guides, interchangeable Coarse and Fine 6" Diamond Plates, an Angle-Guided Field Hone with a three-position ceramic rod (coarse, fine, fish hook groove), and two small diameter ceramic rods for serrations. Sharpens pocket knives, hunting knives, serrations, tools and more. If you are new to sharpening or haven't had success with sharpening stones, activating the Pivot-Response will do the work for you. Pivot response can be engaged to evenly sharpen curved blades - without changing the sharpening motion. 42-Year Warranty.
