Hapstone PlaneShift Series includes components of Hapstone RS (such as stone holders or clamp system) adopted for other sharpening systems: PPA, WSPA, KME, Wicked Edge.
Single-clamp knife sharpeners have consistently been less adaptable than multi-clamp systems when it comes to sharpening various blades, for instance, fillet knives. The Planeshift Clamps Upgrade offers a dual-clamp solution that is compatible with both Work Sharp Precision Adjust and KME knife sharpeners.
How to Use
Attention! To work with the clamps, a 3-mm hex screwdriver is required (not included).
Note. Partial disassembly of the WSPA and KME sharpener is required. It may void the warranty.
