TODAY’S PATENT – NOVEL THINNING SCISSORS

The Thinning scissors was invented by Takashi Sato and was assigned to Hikari Corporation which was later granted patent on 28th April 1992 by the USPTO bearing the patent grant number US5107591A.

It is an object of this invention to provide an improved apparatus capable of cutting and thinning hair in a highly controlled manner. The object of this invention to provide an improved scissors which comprises one blade having a cutting edge and the other blade having a large number of teeth and non-cutting guides arranged there along so that hair can be thinned in a highly controlled manner by the cutting action of the teeth in cooperation with the guides.

It has now been discovered that if non-cutting guides are aligned alongside the teeth of a serrated blade in the prior art, the non-cutting guides part a tress of hair without severing or damaging the hairs so parted, whereas the teeth effectively cut the remaining hairs in a thinning action. When the teeth and the non-cutting guides are properly designed and spaced apart, this further permits the user to cut hair in predetermined proportions, particularly in lesser amounts than prior art thinning scissors can cut.
