Scissors for accessing an acute angle between sewn layers of material
A scissors for cutting a layer of material having a seam with an acute angle includes a first blade and a second blade. The first blade extends to a first tip and has a first cutting edge. The second blade extends to a second tip and has a second cutting edge and an outer edge. The second blade is operatively connected to the first blade to selectively move between an open position and a closed position. The outer edge includes a linear portion extending from the second tip to a curvilinear portion, which defines a fin. The linear portion and the second cutting edge define an acute angle therebetween.
1. A scissors for cutting a first layer of material sewn to a second layer of material with a seam at an acute angle, comprising;
a first blade extending to a first tip and having a first cutting edge extending therealong; and
a second blade extending to a second tip and having a second cutting edge and an outer edge extending therealong, said outer edge positioned opposite said second cutting edge, said second blade pivotally connected to said first blade at a fulcrum and wherein said first and second cutting edges are linear from proximate said fulcrum to said first and second tips, respectively, wherein said first and second blades pivot between an open position for receiving the first layer of material between said first and second cutting edges and a closed position, said outer edge having a curvilinear portion and a linear portion, said linear portion extending from said second tip of said second blade to said curvilinear portion, said curvilinear portion defining a fin, said linear portion and said second cutting edge defining an acute angle therebetween.
2. The scissors of claim 1 , wherein said acute angle is between 10 degrees and 20 degrees.
3. The scissors of claim 2 wherein said acute angle is approximately 16 degrees.
4. The scissors of claim 1 , wherein said linear portion has a length between 5 millimeters and 15 millimeters.
5. The scissors of claim 4 , wherein said length is approximately 8 millimeters.
6. The scissors of claim 1 , wherein said linear portion relative to said second cutting edge defines a maximum width, said fin relative to said second cutting edge defines a maximum fin width, and said maximum width relative to said maximum fin width defines a ratio of approximately 0.15.
7. The scissors of claim 1 , wherein said linear portion and said second cutting edge define a maximum width therebetween of approximately 2.6 millimeters.
8. The scissors of claim 1 , further comprising:
a first handle extending proximally from said first blade and a second handle extending proximally from said second blade, said first and second handles configured to be gripped by an user.
9. The scissors of claim 1 , wherein said second cutting edge and the said fin inclusively define an outer edge angle of less than 45 degrees.
10. The scissors of claim 9 , wherein said outer edge angle is less than 30 degrees.
11. The scissor of claim 1 , wherein the second blade includes a bottom face, and said bottom face is tapered for positioning the cutting edge adjacent to the second layer of material.
12. The scissors claimed in claim 1 wherein said fin projects upwardly away from said first cutting edge to form a generally semicircular fin.
