The Work Sharp Guided Sharpening System is a complete manual 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 system includes an Angle-Guided Bench Sharpener with 17° & 20° 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.
