POWER TOOL AND METHOD

A power tool with a rotatable tool in the form of a saw blade or milling cutter， including a sensor device for detecting a mechanical vector quantity， where the mechanical vector quantity includes a force， an acceleration， a velocity， a deflection， a deformation and/or a mechanical stress and the mechanical vector quantity depends on a force emanating from the tool， and a control device which is communicatively coupled to the sensor device and is adapted to recognize an event and/or a state of the power tool according to a direction and/or change of direction of the mechanical vector quantity detected by the sensor device.
