Claim 0:
1. A saber saw, comprising:
a housing;
a drive motor with an output shaft;
a spindle configured to clamp a saw blade on one end in a cantilevered manner such that the saw blade extends away from the housing and to drive the saw blade; and
a motion converter configured to convert a rotational motion of the output shaft into a reciprocating motion of the spindle, wherein:
the motion converter has an eccentric element driven by the output shaft rotationally about an axis of rotation with a driver part arranged eccentrically to the axis of rotation, and a pendulum element which is mounted pivotably about a bearing point and is connected via a coupling point to the spindle;
the pendulum element has a guide element configured to guide the driver part;
the guide element is arranged between the bearing point and the coupling point;
the bearing point and the coupling point define a first axis of the pendulum element; and
the guide element allows motion of the driver part relative to the pendulum element in a direction along the first axis of the pendulum element, and largely prevents motion of the driver part relative to the pendulum element in a direction perpendicular to the first axis of the pendulum element.
