Abrégé

An improvement for a reciprocal saw is disclosed, the saw being of the type having an oscillating drive shaft and a counter weight that oscillates in opposing phase to the drive shaft for the purpose of reducing vibration. The improvement comprises a lateral extension arm fixed to the counter weight and projecting generally towards the drive shaft. The extension arm is connected to a mounting plate that projects generally parallel to the drive shaft towards the distal end of the drive shaft, such that when the saw is activated the drive shaft oscillates oppositely, but in parallel, to the mounting plate. A mounting cover is fixed to the mounting plate with a fastener and includes a channel therein formed generally longitudinally parallel to the drive shaft and adapted to capture both a first saw blade slidably therein and a second saw blade fixedly therein. The first saw blade is fixed to a blade mounting post of the drive shaft and the second saw blade is fixed to the mounting plate with a blade mounting post thereof. Each blade further includes a slot and slid pin for keeping the distal ends of the blades in close sliding mutual contact.
