Abstract
The device comprises a head portion having a cutting edge with a pair of lever members mounted on opposing sides of the head portion. The lever members are pivotally mounted at one end thereof to move in a crossed relationship with respect to each other and to swing the outer end thereof from a resting position outwardly with respect to the head portion. The outer end of each lever member has a structural configuration effective to cause the swinging movement of the lever members upon contact with the object to be split. The outer end of each lever member contacts the object immediately after the cutting edge contacts the object. The lever members are effective to provide forces via their end portions against opposing sides of a cut formed by the cutting edge and thereby enhance splitting of the object against which the cutting edge has been thrust. The lever members are pivotally mounted to bosses directly attached to the head portion.
