Abstract
A shaving unit includes a skin engagement surface member for contact with the skin in advance of a blade edge and defined by a series of resiliently mounted elements (9) defining between them slots (10) through which hairs can pass while being subjected to a light pulling force to increase the length of hair projecting from the skin prior to cutting. The skin engagement surface member may be a guard of the shaving unit or it can be mounted between two blades.
