Abrégé
(EN)

The invention discloses a novel razor cartridge including a housing having a top, front and back areas, and a bottom, and a plurality of posts each having an end portion extending towards the housing bottom and at least one blade disposed in the housing. Each blade includes a cutting edge and a bottom portion having front and back sides wherein the bottom portion of the blade is disposed adjacent at least one of the plurality of posts. The posts are desirably made of plastic. The end portions of the posts are crushed to provide contact and support to the front and/or back side of the bottom portion of the blades in the housing. The crush force may be up to about 100 lbs-force and the posts are reduced in height by about 20% to about 95%. The crushed posts retain the blades in the housing restricting fore and aft blade movement.
