$2.80 USD 📊 Grit Chart


Empty Blanks are used with sharpening stones on Hapstone and Edge Pro knife sharpener. Edge Pro sharpening stones are fragile and need to be attached to Empty Blanks. This adds rigidity and increases the lifespan of the stones. Empty Blanks have a standard 45-degree bevel and are made of high-quality 3 mm thick aluminum.

How to use

There are two ways to attach sharpening stones to empty blanks:

  • Water-resistant glue with high adhesion to metals and stones. We recommend 3M 77 spray glue. If you have oilstone, use 3M 80 instead.
  • Water-resistant PSA tape with high adhesion to metal and stone. We recommend 3M 90080.

Avoid cyanoacrylate and dual-component epoxy adhesives.
