An electric razor comprises an apertured foil for (1) contact with skin being shaved, and an undercutter (23) urged against the foil and movable relative to the foil, in a direction parallel to a longitudinal axis of the foil, for shearing hairs that protrude through the foil apertures . The foil has a ridge (12) extending along the foil with first and second foil portions (8,9) forming respective flanks of the ridge. The cross-section of the foil is in a plane normal to the longitudinal axis and has an asymmetric arched profile. A first segment (5) of the cross-section taken through the first foil portion (8) has a radius of curvature in the range of 0.5 to 3.0 mm. A second segment (6) of the cross-section taken through the second foil portion (9) is contiguous with the first portion and has a radius of curvature in the range of 5 to 30 mm. The undercutter is in contact with the foil portions at both flanks of the ridge.
