Stalgast Knife Sharpener for Sanelli 22 cm Blades

A knife sharpener built to restore the cutting edge on Sanelli 22 cm meat knives. These blades are ground from steel hardened to 54-56 HRC, a level that holds a keen edge but requires a precise abrasive action to resharpen without overheating or removing excess metal. The sharpener uses a fixed-angle guide that matches the original bevel, so each pass removes only the minimum material needed to expose a fresh, sharp edge.

The process begins with the operator drawing the blade through the guide slot. The abrasive surface contacts the edge at the correct angle, removing microscopic amounts of steel with each stroke. Repeated passes hone the edge until it is uniformly sharp across the entire length. Because the guide is fixed, the operator does not need to judge the angle by eye, which reduces the risk of an uneven edge or accidental damage to the blade.

The unit is a single block of 220 mm length, designed to sit on a worktop or be clamped to a bench. Its compact footprint allows it to be stored in a drawer or cupboard when not in use. The abrasive material is chosen to match the hardness of Sanelli blades, ensuring that the sharpener does not wear out prematurely or require frequent replacement.

Cleaning is limited to wiping the abrasive surface with a damp cloth to remove metal particles after each use. No disassembly is required, and the unit has no moving parts that need lubrication or adjustment.

This sharpener is made for Sanelli 22 cm knives and is not intended for blades of different lengths or hardness levels. It is listed in the Stalgast catalogue under knife maintenance equipment for professional butchers and catering kitchens.
