| Summary: | To improve the cutting properties of a pair of scissors
1,
such as hairdressing shears
11,
it is proposed that at least one shank
4
be made to vibrate parallel to the longitudinal direction (
6
) of the blade (
7
) of this shank (
4
) by means of an electrically powered vibrator (
5
). The vibrator (
5
) may include a piezoelectric travel transducer (
8
), which deflects the blade (
7
) with an ultrasonic frequency. |
