The drawings which accompany and form part of this application illustrate a satisfactoryy embodiment of the improvement reduced to practice and wherein: Figure 1 is a side elevation of the 1mprovement with parts broken away and parts in section. v

Figure 2 is a sectional view on the line 2 2 of Figure 1. Y

20 Figure 3 is a plan view,.of the `drive wheel.

The scissors comprises the usuall cooperating' blades which are pivotally connected together by the usual means 2. One of the blades has a curved haft 3 which 1s round flf in cross section. The haft for the second blade is indicated by the numeral 3 and is of a materially greater length than the haft 3. The haft 3, at .a desired point throughout the lereigth thereof, is widened and the said 80 widen portion is centrally slotted, as'at 5.
