The invention concerns a trimmer comb (1) that comprises a base sheet (10) with a toothed front side that has at least a guard tooth (11) that has a thickened tip (11d) that is made by a process that comprises the steps of (a) forming an intermediate guard tooth (11′) having a protrusion (11 a1) that extends beyond a skin contact edge (L2), (b) bending the protrusion (11a1) of the intermediate guard tooth (11′) over to form a bent-over portion (11a) of the intermediate guard tooth (11′), and (c) applying energy to the bent-over portion (11a) so that a molten tip portion (11 b) is formed. Even for thin base sheets (10), a large sized thickened tip (11d) can be formed and injuries induced by hooking of trimmer teeth can effectively be avoided. The invention is also concerned with a method of manufacturing a trimmer comb.
