Multi-blade bag cutter
A multi-blade bag cutting apparatus for opening a sealed package using one of at least two methods has a first arm partially enclosing a first blade and a first or second arm having a cutout exposing a second blade. The two arms can be injection molded as a single piece of plastic or comprise two separate pieces coupled to a pivot. Preferably, the first blade is partially juxtaposable against a cutting surface, which can be, among other things, a raised portion and/or an anvil.
1. A dual cutting apparatus comprising:
a first arm continuous with a second arm;
a first blade comprising an edge, wherein the edge has a first end, a second end and a central portion;
a first cutter coupled to the first arm, wherein the first arm partially encloses the first blade at the first end and the second end in a manner that exposes at least a segment of 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, and wherein the central portion is operable in conjunction with a juxtaposable first raised portion of the second arm; and
a second cutter coupled to at least one of the first and second arms, wherein the second cutter is distinct from the first cutter and comprises a second blade.

5. The apparatus of claim 4 , further comprising a third blade.
6. The apparatus of claim 3 , wherein the first blade is configured to make a cut in a work piece when used in conjunction with the first raised portion of the second arm.
7. The apparatus of claim 4 , wherein the central portion includes first and second exposed portions, and wherein the first blade is configured to make a cut in a work piece when used in conjunction with the first and second raised portions.
8. The apparatus of claim 5 , wherein the first blade is configured to make a cut in a work piece when used in conjunction with the first raised portion and the third blade is operable in conjunction with the second raised portion.
9. The apparatus of claim 1 , wherein the first cutter is continuous with the first arm.
10. The apparatus of claim 1 , wherein the first blade is at least partially embedded in the first arm.
11. The apparatus of claim 1 , wherein the second arm is a base.
12. The apparatus of claim 1 , wherein at least a portion of the first blade comprises steel.
13. The apparatus of claim 1 , wherein at least a portion of the first blade comprises ceramic.
14. The apparatus of claim 1 , wherein at least a portion of the first blade comprises plastic.
15. The apparatus of claim 1 , wherein at least a portion of the first blade is coated with polytetrafluoroethylene.
16. The apparatus of claim 1 , further comprising a locking strap configured to lock the first cutter and the second arm in a first position.
17. A dual 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 at least a segment of the central portion of the edge of the first blade, and wherein portions of the first arm partially enclosing the first end and the second end project beyond the central portion;
wherein the second arm comprises a raised portion that is juxtaposable against the central portion of the edge of the first blade; and
wherein at least one of the first arm and the second arm comprises a first cutout comprising a second blade.
18. The apparatus of claim 17 , wherein the first arm is contiguous with the second arm at a pivot.
19. The apparatus of claim 17 , wherein the raised portion comprises an anvil.
20. The apparatus of claim 19 , wherein the anvil is a blade.
21. The apparatus of claim 19 , wherein the anvil is completely embedded within the raised portion.
22. The apparatus of claim 19 , wherein the anvil is partially embedded within the raised portion and partially exposed.
23. The apparatus of claim 17 , further comprising a first retractable stop at a first portion of the first arm touching the first end.
24. The apparatus of claim 23 , further comprising a second retractable stop at a second portion of the first arm touching the second end.
25. The apparatus of claim 17 , wherein the first arm is a base.
26. The apparatus of claim 17 , wherein the second arm is a base.
27. The apparatus of claim 17 , wherein the second blade is at an innermost portion of the cutout.
28. The apparatus of claim 17 , wherein the first cutout is within the second arm.
29. The apparatus of claim 17 , wherein the first cutout is within the first arm.
30. The apparatus of claim 17 wherein at least one of the first arm and the second arm further comprises a second cutout comprising the second blade.
