This section treats the abstracts of Perret's "La Pogonotomie" (1770) and "Das Rasiermesser" (1939). Both books describe in detail how - and how not - straight razors must be cared for, and which are the consequences of wrong treatment and techniques. "Das Rasiermesser" is out of print. "La Pogonotomie" has been translated from French into Italian by Mrs. Lorenzi (see the references section).
Note that the information in the archives may or may not apply to
modern razors, depending on the subject. Materials and techniques
have undergone an evolution and insights have changed partially.
The aim of publishing the abstracts is to put the current knowledge
in a historical perspective.
