ABSTRACT:
Cutting shears or scissors have pivotally connected blades and shank portions extending at an acute angle with respect to the cutting edges of the blades wherein handles of the shears connected to the shank portions lie forward of the pivot connection between the blades in the direction of cut of material to be cut by the shears. The shears handles are configured such that the handle to be grasped by the fingers of the operator's hand is fixed to a blade which has a surface adapted for supporting the shears during use thereof. The other blade is provided with a handle particularly adapted for receiving the thumb wherein rotation of the thumb together with thrust of the forearm in the direction of cut or closing action yields a large mechanical advantage without substantial manual effort. Handle configurations include a generally symmetrical handle having a transverse stirrup for engagement with the thumb and a contoured closed loop type thumb handle which is adapted to engage a large area of the thumb including the joint between the metacarpal and phalange bones.
