The invention is directed to a shaving foil for a shaving system of a shaving apparatus, in which the shaving foil cooperates with an undercutter adapted to be driven relative to the shaving foil. The shaving foil includes a perforate region comprised of a plurality of hair-receiving apertures, wherein said apertures form a quasi-periodic pattern executed in accordance with a Penrose parquet.
