A flagrant plug for the trusty safety razor disguised as a comic history of shaving, this witty treat was made by EVH Emmett, whose sardonic tones graced many an educational film in the 1930s and 40s. Jumping from the Bronze Age to Ancient Egypt to the dicey barbers of Victorian England (cue Tod Slaughter hamming it up in "Britain's most fruity drama", Sweeney Todd), the film follows the development and mass production of King Camp Gillette's 1890s invention.
