Böker - black corundum grinding puck

The Böker black corundum sharpening puck is a compact and easy-to-use sharpening tool, primarily suited for larger knives and garden tools such as axes, machetes, spades, and hoes. The sharpening surface is simply moved in a circular motion over the cutting edge.
The corundum, made from the tried and tested abrasive, has two sides with grit sizes of 200 and 600. They are suitable for both wet and dry grinding and each has an effective working surface of 6 cm.
The silica gel trays, which precisely hold the pucks, serve for storage and transport. Each half can also be used as a non-slip handle during the grinding process.
