  • Publication number: 20180009123
    Abstract: A razor head includes a housing and at least one integrally formed rigid razor blade. The housing has a top face defining a shaving window and an opposed stopping face. The razor blades are freely mounted in the housing and have a cutting edge portion and a guided portion. A bent portion is intermediate the cutting edge portion and the guided portion. A cantilever dimension, measured as the distance between the cutting edge and a guided portion axis, is between 1.1 millimeters and 1.8 millimeters. The guided portion cooperates with a guide so that each blade is independently translatable with respect to the housing along a sliding direction parallel to the guided portion axis under the effect of shaving forces applied to the blade during shaving.
