Abstract: Presented is a rib paring device with a linear motion drive, that features a piston rod, that is flexibly guided in the rib paring device in a direction that is longitudinal to the stationary direction of the rib paring device, and that exercises a driving force on the piston rod in the stationary line of action of the rib paring device, the direction of which will change directions periodically, and with combination made up of a blade and a blade holder that features a proximal end and a distal end, the proximal end of which is detachably connected with the piston rod and the distal end of which is detachably connected with the blade.

Abstract: A handheld tool with a pneumatically operated linear oscillating drive is provided. The handheld tool has a motor housing and a piston movable in the motor housing, which separates the two working chambers of the motor housing from one another. A piston crown faces toward one chamber of the two working chambers, with a compressed air supply line toward the motor housing and a slide valve, which controls an alternating supply of compressed air to one and the other of the two working chambers, and with an exhaust air opening in the motor housing. The handheld power tool is distinguished in that the piston additionally has a piston skirt facing toward the other chamber of the two working chambers.
