Sharpeners: simple and robust construction machines
When a wood cutting machine is used for prolonged periods of time, it is natural that the blade progressively loses its ability to cut, and for this reason it must undergo maintenance with the use of sharpeners.
In fact, the blade is no longer sharp after only a few hours of continuous use, and the risk, if it does not undergo maintenance, is that the cutting loses its effectiveness and even lead to the deformation of the blade.
