Abstract
Method and apparatus for opening slits of uneven lengths in the concentric circular shaving sections of an external cutting member that is used in an electric razor using a rotary cutter that cuts the shaving sections of the external cutting member in radial directions as the external cutting member is rotated around its axis by a predetermined angle with a use of an index device. The differences in the length of the slit are obtained by changing the cutting angle of the rotary cutter relative to the external cutting member.
