Description
English: The knife-spine grinding machine is used to shape the back of the blade.

To do so, the knife maker guides the back of the blade along a rotating grinding wheel and shapes it into the desired form. Likewise, the bolster (the transition between blade and handle) is carved out with this machine.
The sounds made when working at this machine are created by the electric motor and the grinding of the spine of the knife on the grinding wheel.
The knife-spine grinding machine is in use at the knife factory Windmühlenmesser Robert Herder in Solingen (Germany, North Rhine-Westphalia), which was founded in 1872. Today the enterprise is in its 4th generation, headed by Giselheid Herder-Scholz. It has maintained techniques and methods of manual knife-making which have vanished more and more with the growth of mechanical fabrication.

In Solingen the production of blades has a long tradition. As early as the 14th century blades were made in large numbers in Solingen. Until the end of the 19th century the entire economy of Solingen was dominated by the cutlery industry.
