Sharpen all your tools with one unit: The Cordless Knife and Tool Sharpener adjusts to multiple blades with angle guides at 15°, 20°, 25° and 30°, while floating back plates allow belt to stay straight without worry of burning the blade tip. Three abrasive belts are included to fine-hone lawnmower blades, shovels, hedge trimmers, straight knives and more. Then put the polish on with a ceramic deburring slot to finish your sharpened edge. Rechargeable lithium ion batteries let you roam cord-free, saving your garage, shed and basement from the scourge of dull blades. Just never loan it out to your neighbor: Tools this good have a habit of disappearing.
