8. A safety razor, comprising:
a unitary handle having a grip portion integrally formed with a head portion comprising a handle pivoting connecting structure and a biasing member,
wherein the biasing member has a first end integrally coupled with the head portion, a substantially straight intermediate portion and a second end having a single cam surface;
wherein the handle pivoting connecting structure comprises a pair of spaced apart arms each terminating in a shell bearing adapted to slidably engage a connecting structure of a razor cartridge to provide pivotal mounting on the handle about a pivot axis, each shell bearing having an inner end and a fin extending therefrom toward the pivot axis in a plane generally perpendicular to the pivot axis and having a tip at the outer end thereof, and
wherein at least a portion of the tip is closer to the pivot axis than any portion of the cam surface of the biasing member, and
a razor cartridge comprising a housing and at least one razor blade having a cutting edge and a body portion adjacent the cutting edge, wherein the housing has a cam surface and arcuate bearing surfaces that slidably engage the handle pivoting connecting structure and have radii of curvature to provide pivotal mounting on the handle about the pivot axis, wherein the cam surface of the biasing member acts upon the cam surface of the housing to provide the razor cartridge an at-rest position and to permit resilient movement of the razor cartridge away from the at-rest position in response to forces encountered during shaving.
