Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A scissors comprising: an upper blade having a handle at one end and a cutting edge at the other end, said upper and lower blades being pivotally connected at a pivot point such that the cutting edges of said blades intersect for cutting purposes when the scissors is operated, and flange means having rounded edges and a substantially planar lower surface integral with the base of the lower blade, the cutting edges of said lower blade extending upwardly from a substantially central portion of said flange means and at a predetermined distance from the forward edge and wherein the flange means extends only a short distance beyond the rear portions of the upper and lower blades to limit exposure of the cutting edges and wherein said upper blade is of a straight configuration which rests on the flange means adjacent the lower blade when the scissors is in a closed position.
Claim 2
Dependent Claim
151 words
A scissors comprising: an upper blade having a handle at one end and a cutting edge at the other end, said upper and lower blades being pivotally connected at a pivot point such that the cutting edges of said blades intersect for cutting purposes when the scissors is operated, and flange means having rounded edges and a substantially planar lower surface integral with the base of the lower blade, the cutting edges of said lower blade extending upwardly from a substantially central portion of said flange means and at a predetermined distance from the forward edge and wherein the flange means extends only a short distance beyond the rear portions of the upper and lower blades to limit exposure of the cutting edges and wherein said upper blade is of a straight configuration which rests on the flange means adjacent the lower blade when the scissors is in a closed position.
Claim 3
Dependent Claim

The scissors of claim 1 wherein: the height of the cutting edge of the lower blade is greatest at the heel of the blade and varies decreasingly toward the front edge of the blade.
Claim 4
Dependent Claim
55 words
The scissors of claim 2 wherein: each of the upper and lower blades comprise a blade portion and a handle defining an obtuse angle therebetween and wherein the handle of the lower blade defines one finger hole and the handle of the upper blade defines one finger hole and an adjacent half-ring for gripping purposes.
Claim 5
Dependent Claim
22 words
The scissors of claim 2 wherein: the flange means is bullet-shaped toward the front tip thereof, to facilitate insertion of the scissors.
Claim 6
Dependent Claim
48 words
The scissors of claim 2 wherein: the flange means comprises a tapered front portion extending beyond the lower blade, an upwardly rounded heel portion which merges with the lower blade handle and having a cross section which tapers outwardly from the center toward the edges of the flange.
Claim 7
Dependent Claim
59 words
The scissors of claim 2 wherein: the flange means comprises a tapered front portion extending beyond the lower blade, substantially parallel side portions and a substantially squared-off rear portion having rounded corners at the intersection with the side portions, said rear portion being located at a point only a short distance beyond the rear surface of the lower blade.
