A method of shaving with a shaving apparatus including an undercutter assembly having a primary undercutter and a secondary undercutter, the primary and secondary undercutters having interleaved blade elements. The method includes the steps of: reciprocally moving the undercutter assembly in hair shearing relation with an outer cutter; moving the primary undercutter relative to the secondary undercutter; trapping hairs which are to be cut between interleaved blade elements of the primary and secondary undercutters; pulling the trapped hairs by continued movement of the undercutter assembly in a respective reciprocation direction; and cutting the hairs between the outer cutter and the undercutter assembly.
