Abstract
The invention relates to a handheld tool, in particular a handheld saw, with an electric drive motor (12), a serially switched gearbox (13), and a movement converter (14) that converts the driven movement of the gearbox (13) into an axial to-and-fro movement of a lifting element (15) for driving a tool (16), in particular a saw blade, inside a housing (11). The gearbox (13) and the movement converter (14) are combined into a gear unit (17). The gear unit (17) is within a robust, bending- and deformation-resistant gear housing (40), which is in turn inside the housing (11). The housing (11) is made of flexible plastic.
