Whetting trestle

The electric whetting trestle from the 1980s is used to further refine the cutting edge of the blade from the point of the knife to the bolster. The blade is pulled evenly along the fine whetting stone. This is one of the last steps in the process of manual blade manufacturing: only at this juncture does the knife achieve its final level of sharpness.
Besides the electric motor, the characteristic sounds of this work can be heard: they are made by the whetting of the blade on the grinding wheel.
The whetting trestle 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.
