Patent ID: 8479401

Claim:
A power hand tool comprising: a motor supported by a frame; a foot including a front portion and a back portion, wherein the foot defines a first plane; a blade disposed between the front portion and the back portion of the foot; a first guide fixedly positioned with respect to the foot and defining a first arc in a second plane orthogonal to the first plane, the first arc having a first arc radius with a first arc origin; a second guide fixedly positioned with respect to the foot and defining a second arc in a third plane orthogonal to the first plane, the second arc having a second arc radius with a second arc origin collocated with the first arc origin, wherein the blade defines a cutting plane substantially orthogonal to the second plane and to the third plane and wherein the intersection of the cutting plane with the first plane defines a pivot axis, the first arc origin and the second arc origin being located at the pivot axis; wherein the first guide and the second guide are offset with respect to one another with the first guide disposed at the front portion of the foot and the second guide disposed at the back portion of the foot; a first pin fixedly positioned with respect to the motor and guided by the first guide; and a second pin fixedly positioned with respect to the motor and guided by the second guide.
