Belgian water stone 6” x 2” x 5/8”

Sharpener: Blue Belgian brocken
Exclusive water Abziehstein from the Ardennes.
The blue national chunk has 30 % a Garnet content and works so thoroughly, but slightly slower.
The thicker layer occurrence in nature allow larger bank stone formats.

Dimensions 6” x 2” x 5/8” Blue stone

How does the Belgian chunk work?
When tool steel is honed, the burr created during grinding is removed and the cutting edge is polished. During this process, the following happens to the Belgian chunk moistened with water:
When the blade of the tool rubs over the evenly fine-grained surface of the stone, the abrasion first causes the softer components of the sedimentary rock such as ash, clay and mica to break off and the embedded garnets to protrude slightly, then they too break away from the parent rock (this is known as grain breakout) and form a thin paste with the water, the grinding paste.
During the uniform grinding movement, the curves of the garnets penetrate the steel easily and remove fine chips from the metal. The hardness of the garnet causes very sharp abrasion, but the round shape of the beads means that no cracks are created, but rather a fine polish. This combination of speed and fineness is unique in the world. It enables a cutting edge to be achieved with which, for example, wood fibers can be cleanly cut across.
