The GardenSharp tool sharpener is designed to sharpen all those single edged, hard to sharpen items in your tool shed, such as lawnmower blades, pruning shears (secateurs), limb loppers, hoes, shovels and scythes. The full-length finger guard protects fingers while the reversible diamond-honed tungsten carbide blade puts your cutting edge in “good as new” condition. GardenSharp will not rust and can be cleaned with soap and water or in the dishwasher.
