Abstract
A safety razor blade unit has a guard structure (5) which includes a strip (10) of elastomeric material e.g. with projections such as fins (12) or tubes (35), and a backstop (13) disposed between the elastomeric strip (10) and the edge (20) of a leading blade (2), the backstop including a rigid wall (15) integrally moulded with the blade unit housing (1) and a resiliently deformable portion (17) integral with the elastomeric strip (10) and adapted to yield under forces experienced during shaving by being compressed against the rigid wall (15) or flexing downwardly.
