摘要： The invention relates to a shaving apparatus comprising a first blade (1) and a second blade (3) having parallel cutting edges (5, 7) extending perpendicularly to a cutting direction X of the blades. The second blade follows the first blade, viewed in the cutting direction. According to the invention, the first blade comprises a blocking element (15) which is provided on a side surface (17) of the first blade at a distance (d) from the cutting edge (5) of the first blade, which distance (d) is much smaller than an average diameter of a hair (25) to be shaved by the apparatus, the first blade being periodically displaceable in the cutting direction by a displacing unit (11) of the apparatus from a first position, in which the cutting edge of the first blade is close to the cutting edge of the second blade, to a second position. In a prefered embodiment, said distance (d) ranges between 10 mum and 50 mum, and is in particular 30 mum. In a preferred embodiment, the blocking element (15) is a front surface (19) of a carrier (13) of the first blade, a blade part (14) comprising the cutting edge of the frist blade being mounted on said carrier. The shaving apparatus performs a retractile action, so that a shaving result achieved by the apparatus is maintained for a long period of time.
