a reciprocal saw mechanism having a housing, a drive motor mechanically connected to an oscillating counter weight having a distal end and an oscillating drive shaft having a distal end projecting through a first aperture in the housing, the counter weight oscillating in opposing phase to the drive shaft, the drive shaft and the counter weight laterally displaced and generally parallel;

a lateral extension arm fixed at a proximal end thereof to the distal end of the counter weight, the lateral extension arm projecting generally towards the drive shaft through a second aperture in the housing and terminating at a distal end;

a mounting plate fixed at a proximal end thereof to the distal end of the lateral extension arm, the mounting plate projecting generally parallel to the drive shaft and towards the distal end of the drive shaft;

a mounting cover fixed to a front side of the mounting plate with a mounting means, the mounting cover including a channel therein formed generally longitudinally parallel to the drive shaft, the channel adapted to capture both a first saw blade slidably therein and a second saw blade fixedly therein with a blade mounting means of the mounting plate, the first saw blade fixed to a blade mounting means of the drive shaft, each blade being mutually slidably fixed at distal ends thereof with a blade fixing means;

whereby the saw drives the first saw blade in one direction while driving the second saw blade in an opposite direction, the first and second saw blades being in close mutual slidable contact.
