This set comes with three replacement blades for the One Step pencil sharpener .
Each blade is made with German steel designed to bend into the unique concave shape of the pencil sharpener.
To replace the blade on your pencil sharpener, simply unscrew the worn blade from the sharpening unit, making sure to keep the nut and bolt in a safe place. Set the old blade aside and align the new blade with the sharpening unit. Replace the nut and bolt and tighten until secure.
