Abstract
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.

A method of shaving with a shaving apparatus including an undercutter assembly having a primary undercutter and a secondary undercutter, said primary and secondary undercutters having interleaved blade elements;
- the method comprising 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 between opposing faces of adjacent interleaved blade elements of the primary and secondary undercutters, the opposing faces extending between inner and outer surfaces of the interleaved blade elements;
- pulling said trapped hairs by continued movement of the undercutter assembly in a respective reciprocation direction;
- and
- cutting said hairs between the outer cutter and the undercutter assembly.
A method of shaving with a shaving apparatus including an undercutter assembly having a primary undercutter and a secondary undercutter, said primary and secondary undercutters having interleaved blade elements;
- the method comprising the steps of:
- reciprocally moving the primary and secondary undercutters of the undercutter assembly in hair shearing relation with an outer cutter;
- moving the primary undercutter relative to the secondary undercutter in a first reciprocation direction;
- whereby said moving primary undercutter entrains the secondary undercutter and continued movement of the primary undercutter causes the secondary undercutter to move with the primary undercutter in the first reciprocation direction,
- reversing direction of moving the primary undercutter,
- whereby continued motion of the primary undercutter causes the secondary undercutter to reverse direction, and
- cutting hairs between the outer cutter and both the primary and secondary undercutters of the undercutter assembly.
