Troublefree operation of a recycling plant relies in particular on the sharpness and service life of the employed knife. It is our goal to ensure that knives re-sharpened by us provide at least the life guaranteed by the manufacturing quality.

Put into practice, this means The bevel angle, surface area and straightness of the re-sharpened knife match exactly what you would find in newly produced knives. That guarantees that the knife will not suffer from decreased performance throughout its entire service life. Each of the materials that will be cut make particular demands on the knife. Hagedorn comes up to these requirements by developing highly specific grinding techniques and helps to solve a variety of complex cutting problems.
