1. A razor blade and support assembly for a razor cartridge, the assembly comprising:
a razor blade having a lower surface and a cutting edge, and
a blade support having an upper portion and lower portion, the upper portion defining a first end and second end, the lower portion extending from the second end of the upper portion at an angle;
wherein extreme lengthwise ends of the lower portion are adapted to engage opposed pairs of slots in each end wall of a housing of the razor cartridge;
wherein the upper portion of the blade support is attached to the lower surface of the razor blade such that the cutting edge of the razor blade is closer to the first end of the upper portion of the blade support than the second end;
wherein the cutting edge of the razor blade is generally parallel to a lengthwise extending intersection between the upper portion of the blade support and the lower portion of the blade support;
wherein the lower portion of the blade support has one or more slots, each slot extending entirely through the lower portion;
wherein the slot enables the assembly to flex near the slot;
wherein at least one slot extends into the upper portion of the blade support;
wherein the blade support further comprises at least one stop surface provided on a projection of the slot; and
wherein the stop surface is adapted to engage rail structure of a housing of the razor cartridge to resist flexural deflection of the razor blade and support assembly in a direction out of the housing of the razor cartridge.
