Methods of manufacturing a hair trimmer attachment

A method of manufacturing a hair trimmer attachment for a hair trimmer, the hair trimmer attachment comprising a fixed blade comprising:

• a skin contacting part forming a surface of the hair trimmer attachment to be placed against the skin of a user, in use of the hair trimmer, and
• an angled part, the angled part being angled relative to the skin contacting part, wherein a plurality of hair openings are spaced apart along a bend between the skin contacting part and the angled part, portions of the fixed blade between the hair openings forming guard teeth of the fixed blade, the method comprising:
• providing a sheet of material for forming the fixed blade;
• deforming the sheet of material to conform to a fixed blade support of the hair trimmer attachment to create the bend between the skin contacting part and the angled part of the fixed blade, the bend being curved and/or angled about an axis extending in a first direction;
• and
• forming a compound curved and/or angled portion on the fixed blade at the guard teeth, such that a surface of the guard teeth is curved and/or angled about the axis in the first direction and is curved and/or angled about an axis in a second direction perpendicular to the first direction,
• wherein a portion of the fixed blade support over which the sheet of material is deformed has a shape comprising a compound curve,
• wherein the compound curved and/or angled portion is formed on the guard teeth by deforming the sheet of material over the fixed blade support at the portion of the fixed blade to bend the sheet of material about an axis extending in a second direction perpendicular to the first direction.
