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 (枢轴的 ) mounted at one end thereof to move in a crossed
relationship with respect to each other and to swing the outer end thereof from
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 utting edge and
thereby enhance splitting of the object against which the cutting edge had been
thrust. The lever members are mounted to bosses directly attached to the
head portion. 14 Claims, 7 Drawing Figures How many claims are there in the patent
