1. A forceps and cutting instrument comprising:
- a pair of opposed, elongated metal arms immovably coupled at a first end and having opposing planar surfaces at a second end for grasping objects therebetween;
a pair of opposed cutting blades extending inward from said arms, said blades being rearward of said second end of said arms, each blade having a planar surface perpendicular to one of said arms, said blades being offset so that said blades extend past each other when said arms are closed toward each other; and
means for biasing said planar surfaces of said blades toward each other when said arms are closed.

Abstract
An improved combination forceps and cutting instrument. A pair of opposed elongated metal arms are coupled to a first end and have opposing planar forceps-grasping surfaces at a second end. Behind this second end are a pair of opposed cutting blades extending inward from the arms. The cutting blades are perpendicular to the arms and form a scissors type cutting mechanism. The blades are biased towards each other so that the cutting edges scrape each other as the instrument is closed.

9. A forceps and cutting instrument comprising:
-
a pair of opposed, elongated metal arms immovably coupled at a first end, said arms diverging outwardly for a first portion and extending inwardly at a second portion from said first portion to a second end of said arms; a pair of opposing planar surfaces coupled to said second ends of said arms for grasping objects therebetween; a pair of opposed cutting blades attached to said second portions of said arms, each blade being offset relative to the other so that said blades extend past each other when said arms are closed, said blades having aligned, elongated slots extending in a direction substantially perpendicular to said second portion of said arm, at least one of said blades having a serrated edge extending rearwardly from proximate said second end of said arm and toward the other arm; and a rivet extending through said slots for holding said blades in close proximity.
