Hapstone Hex Screwdriver

Many guided knife sharpeners include L-shaped Allen keys, the least expensive tool to handle hex screws. Hex screwdrivers are much easier to use than Allen keys. If you use your sharpener regularly, hex screwdrivers will make your life comfortable.

Ball-End 4 mm Hex Screwdriver is recommended by Hapstone for R2 sharpening systems.
