Bag cutter and piercer
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.
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;
a first piercer and a second piercer, each extending outward from an edge of the first arm, and the first piercer having a first tip, wherein the first tip extends toward the second piercer;
a second blade positioned between the first piercer and the edge of the first arm;
a third blade positioned between the second piercer and the edge of the first arm; and
wherein an angle between a cutting edge of the second blade and a cutting edge of the third blade is less than or greater than 180°.
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 piercer and the second piercers each has a substantially mirrored shape with respect to each other.
6. The apparatus of claim 1 , wherein the second blade bridges a gap between the first piercer and the edge of the first arm.
7. The apparatus of claim 1 , wherein the second arm has a breadth, and the first piercer extends beyond the breadth of the second arm.
8. The apparatus of claim 1 , wherein the second arm has a breadth, and the first piercer extends within the breadth of the second arm.
