The anticorosive surface coating protects the tool from oxidation, i.e. rusting. A solid lubricant is used in the safety mechanism which is also made from stainless steel. Given these circumstances, the tool does not require any special kind of maintenance. The tool may be cleaned with all common types of cleaners, except those on the basis of chlorine. This exception pertains to the cleaning of the plastic coating on the handle. Remove any dirt off the belt after each use. The belt should be dried and stored in a dry environment with the maximum 90% relative humidity.
Sharpening the tool
To sharpen the tool, you may utilize any common processes and means of sharpening manual/handheld tools. For the shape and measurement details of the edges, see figures below. Attention! The sharpening process must not change the mechanical attributes of the blades, i.e. the edges may not be annealed as the heat would change the mechanical properties of the material.
For more information, see the manual.
