A razor blade assembly is provided for mounting on a handle via a pivotal connection, the handle having a spring-biased cam follower, the assembly including a housing that carries three blade members, a guard portion, a cap structure and arcuate bearing surfaces below the blade carrying portion that pivotally engage shell bearing connections of the handle. The pivot axis of the razor blade assembly is located above the arcuate bearing surfaces for movement along an arc between a forward pivot stop position and a rearward pivot stop position. The housing has a cam surface having an apex located relative to the arcuate bearing surfaces to provide an at-rest position at a location other than the midway position between the pivot stop positions and to permit movement away from the at-rest position against spring bias force of the cam follower in response to pivotal forces encountered during shaving.
