An integrally formed rigid razor blade is provided. The razor blade includes a cutting edge portion extending along a cutting edge portion axis and having a cutting edge at one end, a base portion extending along a base portion axis, and a bent portion intermediate the cutting edge portion and the base portion. The bent portion has an average radius of curvature of between 0.4 millimeters and 1.00 millimeters. The cutting edge portion has a cantilever dimension which is a constant distance of between 1.1 millimeters and 1.8 millimeters when measured from the cutting edge portion to the base portion axis.

Razor blade, razor head, and method of manufacture

An integrally formed rigid razor blade made of martensitic stainless steel includes a cutting edge portion, a base portion, and a bent portion. The cutting edge portion extends along a cutting edge portion axis and has a cutting edge at one end. The base portion extends along a base portion axis. The bent portion is intermediate the cutting edge portion and the base portion. The blade has a concave face and an opposed convex face. An average radius of curvature of the concave face of the bent portion is between 0.4 millimeters and 1 millimeter.

An integrally formed rigid razor blade has, in cross-section transverse to a longitudinal axis, a cutting edge portion, a base portion, and a bent portion. The cutting edge portion extends along a cutting edge portion axis and has a cutting edge at one end. The base portion extends along a base portion axis and has a rear edge at one end. The bent portion is intermediate the cutting edge portion and the base portion. The rear edge of the base portion is serrated along the longitudinal axis. The serrations have a height of between 0.13 millimeters and 0.32 millimeters.

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.
