摘要：
A shaving system includes air engaging edge structure fixed in position between a guard member and the cutting edge of a blade member. The hair engaging edge portion has an effective dimension relative to the dimension of hair elements to be shaved such that in the course of a normal shaving stroke the edge portion engages hair elements and produces localized distortion in those engaged hair elements to exert a grasping effect on the individual hair elements which pulls them outwardly from their hair follicles as the shaving system is moved over the skin surface in a shaving stroke.
