Abstract

A cutting apparatus for opening a sealed package has a first arm partially enclosing a first blade that is at least partially juxtaposable against a second arm having a cutting surface. The two arms can be injection molded as a single piece of plastic or comprise two separate pieces coupled to a pivot. Preferably, the cutting surface comprises a raised portion at least partially enclosing a hard anvil.

Claims

1. A cutting apparatus comprising:

a first arm and an opposable second arm;

a first blade comprising an edge, wherein the edge has a first end, a second end and a central portion;

the first arm partially enclosing the first blade at the first end and the second end in a manner that exposes the central portion of the edge of the first blade wherein portions of the first arm partially enclosing the first end and the second end project beyond the central portion;

a first raised portion on the second arm at least partially enclosing an anvil, wherein the anvil comprises a first material, and the second arm comprises a second material different from the first material; and

wherein at least one of the first raised portion and the anvil is juxtaposable against at least a first segment of the central portion of the edge of the first blade.

2. The apparatus of claim 1, wherein the first arm is continuous with the second arm.

3. The apparatus of claim 1, wherein the first arm is conjoined with the second arm at a pivot.

4. The apparatus of claim 1, wherein the first arm and the second arm comprise a continuous piece of plastic.

5. The apparatus of claim 1, wherein the first blade is embedded in the first arm.

6. The apparatus of claim 1, wherein the central portion is flat at a juxtaposition with the anvil or the first raised portion, and wherein the anvil or the first raised portion comprises a bubble surface.

7. The apparatus of claim 1, wherein the central portion of the edge of the first blade is concave at a juxtaposition with the anvil or the first raised portion.

8. The apparatus of claim 1, wherein the central portion of the edge of the first blade is convex at a juxtaposition with the anvil or the first raised portion.

9. The apparatus of claim 1, wherein the anvil is not a blade.

10. The apparatus of claim 1, further comprising a first retractable stop at a first portion of the first arm touching the first end of the edge of the first blade.

11. The apparatus of claim 10, further comprising a second retractable stop at a second portion of the first arm touching the second end of the edge of the first blade.

12. The apparatus of claim 1, wherein the first blade has a long axis parallel to a long axis of the anvil.

13. The apparatus of claim 1, wherein the first blade has a long axis orthogonal to a long axis of the anvil.

14. The apparatus of claim 1, wherein the anvil comprises a compound convex surface.

15. The apparatus of claim 1, wherein the anvil comprises at least a portion of at least one of the following:

a ball, a cylinder, and a cone.

16. The apparatus of claim 1, further comprising a hole configured to accept a hanger.

17. The apparatus of claim 1, wherein the first raised portion completely encloses the anvil.

18. The apparatus of claim 1, further comprising a locking strap.

19. The apparatus of claim 1, further comprising a ridge on the first arm on a side opposite to the side partially enclosing the first blade.

20. The apparatus of claim 1, wherein at least a portion of the edge of the first blade comprises steel.

21. The apparatus of claim 1, wherein at least a portion of the edge of the first blade comprises ceramic.

22. The apparatus of claim 1, wherein at least a portion of the edge of the first blade comprises plastic.

23. The apparatus of claim 1, wherein the first arm is a base.

24. The apparatus of claim 1, wherein the second arm is a base.

25. The apparatus of claim 1, wherein the second arm comprises a second raised portion that is juxtaposable against a second segment of the central portion of the edge of the first blade.

26. The apparatus of claim 1, further comprising a second blade, wherein the first arm partially encloses the second blade in a manner that exposes at least a portion of an edge of the second blade, and wherein a second raised portion is juxtaposable against the second blade.
