Abstract

A bag cutter for opening a sealed package using at least one of a blade and a piercer. Preferably, at least one blade is disposed partially within a cutout of an arm in a manner that exposes an edge of the blade. A piercer can comprise an extension of a cutout edge or be located on any other suitable portion of an arm. Another blade can be provided that is substantially perpendicular to the blade within a cutout, and juxtaposable against a cutting surface.

Claims

1. A cutting apparatus, comprising:

a first arm having a first inner surface and an opposable second arm having a second inner surface opposite the first inner surface;

a first blade partially embedded in and extending from the first arm;

a cutting surface extending from the second arm toward the first blade; and

a first and second piercer extending outward from an edge of the first arm.

2. The apparatus of claim 1, wherein the first piercer extends toward the second surface.

3. The apparatus of claim 1, wherein the first piercer extends away from a space between the first and second arms.

4. The apparatus of claim 1, wherein the first piercer extends toward a space between the first and second arms.

5. The apparatus of claim 1, wherein the first and second piercer have a substantially mirrored shape with respect to each other.

6. The apparatus of claim 1, further comprising a second blade positioned between the first piercer and the edge of the first arm.

7. The apparatus of claim 6, further comprising a third blade positioned between the second piercer and the edge of the first arm.

8. The apparatus of claim 6, wherein the second blade bridges a gap between the first piercer and the edge of the first arm.

9. The apparatus of claim 1, wherein the second arm has a breadth, and the first piercer extends beyond the breadth of the second arm.

10. The apparatus of claim 1, wherein the second arm has a breadth, and the first piercer extends approximately within the breadth of the second arm.

11. The apparatus of claim 1, further comprising a first wiper extending from the first inner surface toward the second inner surface.

12. The apparatus of claim 11, wherein the first wiper is substantially longitudinal to the first inner surface.

13. The apparatus of claim 11, wherein the first wiper is at least approximately 5 degrees askew to longitude of the first arm.

14. The apparatus of claim 11, wherein the first wiper extends toward the first blade.

15. The apparatus of claim 11, further comprising a second wiper.

16. The apparatus of claim 15, wherein the second wiper extends from the second inner surface substantially opposing the first wiper.

17. The apparatus of claim 15, wherein pressing the first arm toward the second arm juxtaposes at least a portion of the first wiper to the second wiper.

18. The apparatus of claim 17, wherein a portion of the first blade meets a portion of the cutting surface when the portion of the first wiper and second wiper are juxtaposed.

19. The apparatus of claim 11, wherein the first wiper is greater than approximately 1 inch long.

20. A cutting apparatus, comprising:

a first arm having a first inner surface and an opposable second arm having a second inner surface opposite the first inner surface;

a first blade partially embedded in and extending from the first arm;

a cutting surface extending from the second arm toward the first blade; and

a first wiper.

21. The apparatus of claim 20, wherein the first wiper extends from the first inner surface toward the second inner surface.

22. The apparatus of claim 20, further comprising a third arm having a third inner surface and an opposable fourth arm having a fourth inner surface opposite the third inner surface.

23. The apparatus of claim 22, wherein the first wiper extends from the third inner surface toward the fourth inner surface.

24. The apparatus of claim 23, wherein the first wiper is substantially longitudinal to the third inner surface.

25. The apparatus of claim 22, wherein the first wiper is at least approximately 5 degrees askew to longitude of the third arm.

26. The apparatus of claim 22, further comprising a second wiper.

27. The apparatus of claim 22, wherein the second wiper extends from the fourth inner surface substantially opposing the first wiper.

28. The apparatus of claim 22, further comprising a first piercer extending from an edge of the third arm.

29. The apparatus of claim 28, further comprising a second blade spanning a gap between the first piercer and the edge of the third arm.

30. The apparatus of claim 28, further comprising a second piercer extending from the edge of the third arm.

31. A cutting apparatus, comprising:

a first arm coupled and opposed to a second arm;

a protrusion extending from the first arm toward a receiving portion of the second arm, the receiving portion including a trough bounded by a first lip;

a piercer embedded in the first lip; and

a blade spanning a portion of the trough;

wherein the protrusion is positioned substantially opposite the piercer.

32. The cutting apparatus of claim 31, wherein the piercer extends from the first lip toward the second arm.

33. The cutting apparatus of claim 31, wherein pressing the first and second arms together abuts a portion of the protrusion to the first lip.

34. The cutting apparatus of claim 31, wherein the portion of the protrusion comprises a ridge on the protrusion.

35. The cutting apparatus of claim 31, further comprising a second lip bounding the trough and opposite the first lip.

36. The cutting apparatus of claim 35, wherein the blade spans between the first lip and the second lip.

37. The cutting apparatus of claim 31, wherein pressing the first and second arms together draws a material, via the protrusion, into contact with the piercer.

38. The cutting apparatus of claim 31, wherein the protrusion is positioned at a front edge of the first arm, and wherein the first lip is positioned at a front edge of the second arm.

39. The cutting apparatus of claim 31, wherein protrusion is positioned at a side edge of the first arm, and wherein the first lip is positioned at a side edge of the second arm.
