1. A tool for cutting and/or grasping pieces of food particles or human tissue, said tool comprising:

  • (a) a pair of jaw members, each having one end an extending end and a generally similar extending length, therebetween with one of said jaw members being relatively fixed and with one of said jaw members being relatively movable with respect to the other;

    (b) a first pivot connection between said pair of jaw members located at one end thereof, said first connection comprising a first slot formed in one of said jaw members that extends along an axis generally parallel to the extending length of said one jaw member, and a first pivot pin fixed to the other of said jaw members and disposed in said first slot;

    (c) a second camming connection between said pair of jaw members located between said first pivot connection and the extending ends of said jaw members, said second camming connection including a second slot formed in one of said jaw members that extends along an axis disposed at an acute angle to said extending length of said one jaw member, and a second pin fixed to the other of said jaw members and disposed in said second slot; and

    (d) an operating member attached to said relatively movable jaw member at its end opposite its said extending end and arranged to exert on said movable jaw member a pulling and pushing force directed generally parallel to the extending length of said relatively fixed jaw member, said pulling force causing said movable jaw member to have a first pivotable component of movement about said first pivot connection relative to said fixed jaw member, and to have a second lateral component of movement about said second camming connection to cause said movable jaw member to move laterally relative to said fixed jaw member in a direction generally parallel to the extending length thereof and in a direction generally toward said first pivot connection, whereby said first pivot connection and said second camming connection cooperate to cause said pulling force to be applied to said movable jaw member in an increasing amount during its movement toward said fixed jaw member.
