To achieve the practical use of a pair of barber scissors having the so-called sliding-cutting function.

In the barber scissors configured of blade bodies each including a cutting blade and a handle, a gear accommodation hole 13 is formed at a pivotal joint intersection of one blade body 1; a rack 14 is formed on the inner-surface of the gear accommodation hole; and a guide groove 15 is formed in the outer-surface of the blade body 1. In the pivotal joint shaft position of the other blade body 2, a pinion 4 having arclike teeth 42 to engage with the rack is mounted to rotate together with the blade body 2; a guide body 5 having a projection to fit into the guide groove is disposed striding the outer-surface of the gear accommodation hole; and a nut 6 is screwed and mounted on the pivotal joint screw shaft 32 protruding from the shaft hole 53 of the guide body.
