The set comes with three replacement blades for the Blackwing One-Step Long Point Sharpener. Each blade is made from German steel designed to bend to the One-Step sharpener's unique concave shape.
To replace your sharpener's blade, simply unscrew the worn out blade from the sharpening unit, making sure to keep the nut and screw safe. Set the old blade aside and align the new blade on the sharpening unit. Replace the screw and nut and tighten until secure.
