Today we’re used to the big multinationals sticking yet another blade on their razor and hailing it as the greatest breakthrough in shaving since the blunt stick… but the idea of “one blade good, more blades better” came quite soon after the Gillette safety razor hit the market. One of the earliest I’ve found so far was patented by Mr Herbert G. Harrison in 1909.
1. A razor provided with a plurality of superposed blades, and with means for rigidly securing the cutting edges of said blades in such a close relation to each other that said edges may be simultaneously used for shaving the same spot, substantially as described.
2. A razor provided with a plurality of overlying blades and with means for rigidly securing the cutting edges of said blades one slightly behind the other and in such a close relation to each other that said edges may be simultaneously used for shaving the same spot, substantially as described.
3. A razor provided with a plurality of superposed removable blades, means for spacing said blades, and means for rigidly securing the cutting edges of said blades in such a relation to each other that said edges may be simultaneously used for shaving, substantially as described.
4. A safety razor provided with a guard, a plurality of overlying blades, and with clamping means for rigidly securing the blades in such a relation to each other that their cutting edges may be simultaneously used for shaving, substantially as described:
5. In a safety razor the combination of a plurality of superposed removable blades with curved clamping means, comprising a distance piece, for rigidly securing the blades in such a relation to each other that their cutting edges may be simultaneously used for shaving, substantially as described:
6. In a safety razor the combination of a plurality of superposed blades, a distance piece having eccentric curved surfaces; and means for rigidly securing said piece and blades in such a relation that the cutting edges will be presented to the skin simultaneously in the act of shaving, substantially as described.
7. In a safety razor the combination or a plurality of superposed blades with clamping means for rigidly securing the blades with the cutting edge of the one slightly in advance of the cutting edge of the other and in such relation to each other that their cutting edges may be simultaneously used for shaving, substantially as described.
8. A safety razor provided with a guard, a plurality of overlapping blades, an with means for securing the cutting edges of said blades in such a relation to each other that said edges may be used simultaneously for shaving, substantially as described.
