Abstract

A movable blade cartridge including a platform member having a blade seat and a guard member. The guard member is located of forward and parallel to the blade seat so as to form a longitudinal slot between the blade seat and the guard member. A
primary blade which is disposed on the blade seat such that the cutting edge of the blade is located rearwardly of the guard member. A substantial portion of the primary blade extends into the slot formed between the guard member and the blade seat such that the blade is flexible into the slot. A spacer is located on the upper surface of the primary blade. The spacer comprises a rear portion which functions to separate the primary blade and a secondary blade, as well as a forward portion which extends from the rear portion and functions to prevent upward movement of the primary blade, and create an opening beneath the forward portion of the spacer and the lower surface of the secondary blade. Both the primary and secondary blade are manufactured and mounted so as to be flexible in response to forces encountered during the shaving operation. The blade cartridge also includes a cap member disposed on the secondary blade which prevents upward movement of the second blade.
