Summary: | The present disclosure relates to a method of forming a sheet-metal based double-walled stationary blade (24) for a hair cutting appliance (10), the method comprising: providing a first pre-product layer (70), providing a second pre-product layer (72) which is separate from the first pre-product layer (70), providing a guide slot (44) for a cutter (26), and bonding the first pre-product layer (70) and the second pre-product layer (72) to one another such that the pre-product layers (70, 72) are arranged to jointly receive a to-be-mounted cutter (26), wherein the first pre-product layer (70) and the second pre-product layer (72), in the bonded state, are at least partially offset from one another to provide a defined mating clearance fit for the to-be-mounted cutter (26), wherein the pre-product layers (70, 72) are bonded to one another at their longitudinal ends such that stationary blade teeth (54) are partially formed by the first pre-product layer (70) and partially formed by the second pre-product layer (72), and wherein tips (56) of the stationary blade teeth (54) are arranged adjacent to a transition zone (84) between the pre-product layers (70, 72). The present disclosure further relates to a cutting appliance and to a blade set (22) for such an appliance. |
