The comb-frame having a comb portion with plurality of comb-teeth (32) flanked on either side by side-arms (26) has a rectangular horizontal through-hole (34) in its top portion to receive a shaft (46) of the detachable handle which may be temporarily fixed on any one of its two sides, right or left, thereby offering option of right-hand or left-hand use. The side-arms of the comb-frame have grooved tracks (28) to allow slidably mounting of the blade-holder. The blade-holder has a cutting blade (36) fixed on its inside surface.
