Empty Glass Blanks are used with lapping films for the ultra-fine sharpening of knives and tools using KME or Hapstone knife sharpeners. The bar made of glass is attached to high-quality durable aluminum blank.
We recommend to use PSA lapping films with glass blank. PSA-backed (pressure sensitive adhesive) lapping film is extremely easy to use. Simply peel off the paper backing and press it down on the blank. Avoid getting air bubbles between the film and the blank.
To apply non-adhesive lapping film, use double-sided adhesive tape or acrylic glue.
