The Revisor Company goes back to 1919 but went out of business in 1990.
The Revisor name was renewed at the German patent office in 2000 and a new collection of cut throat razors was developed, Revisor also reintroduced some New Old Stock (NOS). This NOS of shave ready razors includes the legendary Puma razor. A mark of the quality of Revisor razors today is that they are made by some of the same skilled workers who worked during the company's heyday. Some of these workers are now in their 70s, and are passing their skills onto a new generation.
Revisor razors in our experience typically leave the workshop in a more ‘shave ready’ condition than other brands.
