Hollow Grinding

Hollow Grinding

Concave form on knife blade

Hollow grinding produces a concave form on the knife blade.  Products made by this type of grinding are pocket knives, smaller kitchen knives and multi-tools.  This process uses Type 6 cup wheels being used simultaneously.  Hollow grind gives the knife blade a thinner blade producing a knife that will cut quickly, with minimal effort.
