Abstract: A cutting attachment is provided having a first body member, a second body member and a plurality of pins spaced an equi-distance apart for connecting the first body member to the second body member to form a rigid body wherein at least a portion of the first and second body members are spatially disposed a distance apart, each of the pins having a bearing surface substantially corresponding in length to the distance between the first and second body members.

Abstract: A circular saw blade assembly adapted to be secured to a power-driven saw arbor and rotated thereby, which comprises a circular saw blade formed of first and second discs, the discs defining a central bore extending through a medial portion thereof and diverging radially from the medial portion to form a relief opening extending to the peripheral portion of the disc so as to define a chain track peripheral portion, disc connector elements disposed within the relief opening for connecting the first and second discs at a position between the medial portions of the disk and the chain track peripheral portion, and a chain saw having a plurality of cutter elements projected outwardly from one side thereof and a plurality of drive link elements projecting outwardly from an opposite side thereof, the saw chain extendible about the perimeter of the first and second discs such that the drive link elements are disposed within the chain track peripheral portion and frictionally engage the first and second discs defining
