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

  • Water-resistant glue with high adhesion to metal and stone. We recommend 3M 77 spray glue.
  • Water-resistant PSA tape with high adhesion to metal and stone. We recommend 3M 90080.

Avoid cyanoacrylate and dual-component epoxy adhesives.
