20th Century Correspondence School, Shaving Made Easy (1905)
“ One thing may be said of safety razors in general—that if a man uses one he is less likely to cut himself, but this is all that can reasonably be said in their favor. Of course, if it were impossible to shave with the ordinary razor without cutting one's self, then the safety razor would become a necessity. The truth is, however, that anyone who has a good keen smooth-cutting razor, lathers the face thoroughly, and will learn—if he does not already know—how to handle the razor properly, will run almost no danger. Such a man will seldom cut himself. ”
