Manufacturing of straight razors
A high-quality razor is made in the smithy, gets its hardness in the hardening shop, is ground in the grinding shop and finally artfully damasked.
The razor in the smithy
In a first step, the blank of the razor is obtained from a steel gap between 20 and 50 mm wide and 5 to 6 mm thick. The annealed gap is forged under the high pressure of a drop hammer in the raw form, the die, hot. The superfluous ridge (wing) is split off and the finished blank is rolled out.
hardening
Of great importance is the tempering (hardening) of the blank, which is heated up to 1300 ° C depending on the steel quality and then quenched in a special oil. The temperature limits are decisive in this process and are subject to the professional secrecy of each hardener. Tempering the blank at about 200 ° C to 400 ° C gives the blade its subsequent resilience and toughness. Additional ice-creaming at -40 ° C creates, depending on the steel, the further seal of the material structure.

Grinding the razor
In the grinding shop the blade is created from the obtained blank. From the hollow grinding through the grinding of the back and the back, the pounding (fine grinding) of the hollow side and the back, the polishing of the blade and the final blue puffing of the hollow side (creates the even matte finish), the razor is created, which has to be finally finished, i. the blade is embedded in the shell halves of the handle by means of nickel-silver nails. The decorating etchings and possibly gilding (Damaszierarbeiten) complete the value of the razor blade. Each knife is tested, peeled off and padded by experienced professionals. Polishing work on the handle and blade, as well as the careful greasing and cleaning complete the production.
