Abstract
Razor handles with integrated spring elements and/or methods of fabricating the same. In one example, a handle for a razor can comprise a head portion and a spring element having a distal end and a proximal end that longitudinally opposes the distal end to define an arc length of the spring element. The head portion can facilitate coupling razor cartridges in pivotal relation with the handle. The spring element can extend integrally from the head portion at the proximal end. The spring element can deflect as an abutment surface on the distal end travels in sliding engagement with a cam surface of a razor cartridge to an end point of the cam surface while exerting progressively increasing return torque as the razor cartridge rotates about a front pivot axis from a neutral position. The end point can fall proximal to a rear edge of the razor cartridge.
