This invention comprises a focused light attachment for use with a portable power-driven hand saw, particularly a saber saw. The invention comprises a light source such as an electric lamp with a suitable electrical power source and a focusing mechanism for projecting a very narrow beam of light. The light source and focusing mechanism is mounted on the front of the hand saw and is positioned to project its narrow light beam a substantial distance in front of the saw blade so that it can be used to trace or follow a previously scribed saw line. The tracing light can be used in combination with a flood light that is mounted also on the front of the saw housing and positioned to flood the area surrounding the saw blade with illumination. Most preferably, the tracing light and its focusing mechanism are mounted permanently within the housing of a saber saw.
In a portable, power-driven, hand-held sabre saw having a tool casing including a motor housing with a motor mounted therein, a handle, a gear train and a straight, flat and narrow saw blade mounted for reciprocating movement thereon, the improvement comprising:
