BLADE UNIT FOR A SAFETY RAZOR

摘要

A blade unit for a safety razor comprises a plurality of elongated blades (4) with a continuously curved cutting edge (8). The shape of the cutting edge (8) is defined according to the formula Rcur-k?L, where Rcur is the bending radius of the blade; k is a coefficient of proportionality ranging from 1 to 5; and L is the chord length of a curve with a radius of R11x. The blades (4) have a third support point. This provides for easy and effective shaving.
