PURPOSE: To easily change the projecting length of comb teeth adjacent to a blade edge in a cut razor, by providing positioning uneven surface parts for setting the positions of tip ends of the comb teeth at several stages with respect to the blade edge, between the outer part of a blade attaching part and the comb teeth body.

CONSTITUTION: A blade 5 clamped between superposed clamping plate parts 3, 4 is projected from a flank side opening 6 defined between the clamping plate parts 3, 4. A comb teeth body 8 is fitted onto the clamping plate parts 3, 4 on the rear part 7 remote from the opening 6, and opposite plate parts 11, 12 of the comb teeth body 8 is locked in a locking groove 16 formed in one of both clamping plate parts 3, 4 so that the tip ends of comb teeth 14 approach the flank side opening 6 when the fitting part of the comb teeth body 8 is lifted up and then a rear plate part 10 thereof is separated from the rear part 7. That is, the projecting length of the comb teeth can be changed so as to obtain a desired hair cutting length.
