Abstract

The tool incorporates an elongated cutting blade (2), a gas distributor (11) and an alternating pneumatic motor (1) effecting longitudinal blade reciprocation. A conventional sole plate (6) locating normally at the blade tip supports the tool beneath the workpiece on a table top. A partial blade enclosing guard (7) extends between the sole plate and motor, and blade sharpening grinders are connected to the piston rod of the ram motor. The ram imparts a rotary oscillatory movement to a shaft which is parallel to the piston rod and blade. The shaft produces an alternating movement of each grinder in a plane perpendicular to the blade, the grinders engaging the blade edge during each movement.
