Abstract
The present disclosure is directed to a shaving cartridge for use with a razor handle having a pair of cartridge engaging shell rocker bearings biased toward one another each of which has at least one undercut rocker bearing for receiving the cartridge. The cartridge has at least one blade thereon and has curved under surfaces pivotal upon and relative to the rocker bearing surfaces of the cartridge engaging shell rocker bearings. At least one protrusion extends from the curved under surfaces of the cartridge and is positioned to engage the shell rocker bearing surfaces on the cartridge when the cartridge is introduced to the shell bearings of the handle to bar reverse insertion of the cartridge in the handle so that the shaving blade of the cartridge when rockably engaged within the grip of the shell bearings is in a shaving ready position every time avoiding accidental reversal of the cartridge and its cutting blades when positioned on the handle for shaving.
