Planeshift Clamps Upgrade for Work Sharp Professional Precision Adjust

Hapstone PlaneShift Series includes components of Hapstone RS adopted for other sharpening systems.

Single-clamp knife sharpeners have consistently been less adaptable than multi-clamp systems when sharpening various blades, for instance, fillet knives. The Planeshift Clamps Upgrade is a dual-clamp solution for Work Sharp Professional Precision Adjust knife sharpeners.

How to Use

Installation Guide

1. Remove the Original V-Clamp: We won't be using the original V-clamp for this setup, so the first step is to press the release button and remove it. Set it aside.
2. Install the Clamp Frame: (Can be pre-installed) Install the Clamp Bar into the center, aligning it with the slot. Use the small spacer provided along with the screw to protect the frame itself. Slot everything nicely into position, and then snug the screw into place.
3. Install the Hapstone Clamps: (Can be pre-installed) Once the clamp bar is secured, simply attach your Hapstone clamps onto the clamp bar. These clamps are extremely versatile—they can swivel inwards, outwards, and can be positioned anywhere you need them. For larger knives, they can be placed on the sides. These clamps also slide along the frame, giving you flexibility depending on the knife size or shape. Additionally, since this is a Hapstone clamp frame, you can use any of the Hapstone clamps available, allowing you to clamp nearly any knife with the right combination of clamps.
4. Install the Support Block: To minimize flex while sharpening, install the support block at the bottom of the system. Push it all the way back—it may require tilting the system slightly to fit it properly. This block will prevent any downward movement, giving you more stability during sharpening.
5. Install the Clamp Upgrade: Once everything is assembled, all you need to do is slide the entire clamp upgrade into position as you would with the original V-clamp. Lock it into place.
