The invention relates to a multi-part cut guard for a tool that is rotatable in a cutting plane. The cut guard includes a first part element and at least one further part element. The part elements are connected together at their ends and form a closed circumference. Opposing first ends of the part elements are connected together, forming a pivot joint. The second ends of the part elements are fixed releasably together. The pivot joint is formed from a latching receptacle and a latching stub which form the pivot joint in the latched state and are intended to be separated in order to release the latching.

A starter device for an internal combustion engine has an entrainer for coupling to the engine. The entrainer and an actuator of the starter device are mounted rotatably about a rotational axis. A damper spring is arranged between and operatively connects the entrainer and the actuator to each other. The starter device has at least one stud, on whose outer periphery the damper spring is mounted. The damper spring is a hinge spring wound from a spring wire. The cross section of the spring wire is rounded on the inner side of the spring wire. At least a portion of the cross section runs linearly on the outer side of the spring wire.

A portable handheld edge cutter () has a cutterhead () fixed to a guide tube (). Two wheels () are attached to the cutterhead (). The cutterhead () includes a gear unit mounted in a gear housing (). A first wheel () is rotatably journalled on a first end () of the gear housing (). On the opposite-lying end () of the gear housing (), a cutting knife () is mounted and is rotatably driven by the output shaft () of the gear unit. In order to achieve a simple assembly of the edge cutter () and to protect the gear housing () against wear, the second wheel () is mounted between the gear housing () and the cutting knife () and that the two wheels () are journalled coaxially to the output shaft ().
