Power tool and method

A handheld power tool with a rotatable tool, wherein the rotatable tool is a saw blade or a milling cutter, wherein the handheld power tool comprises:

• a sensor device for detecting a mechanical vector quantity, wherein the sensor device is adapted to detect the mechanical vector quantity as an at least two-dimensional vector by measuring a mechanical quantity underlying the mechanical vector quantity in at least two different spatial directions,
• wherein the mechanical vector quantity comprises 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 rotatable tool, and
• a control device communicatively coupled to the sensor device, which control device is adapted to recognize an event and/or a state of the handheld power tool according to a direction and/or a change of direction of the mechanical vector quantity detected by the sensor device,
• wherein the sensor device comprises a first sensor element and a second sensor element, the first sensor element being adapted to measure the mechanical quantity underlying the mechanical vector quantity in a first spatial direction and the second sensor element being adapted to measure the mechanical quantity underlying the mechanical vector quantity in a second spatial direction different from the first spatial direction,
• wherein the handheld power tool further comprises a support structure and an output shaft mounted on the support structure, to which output shaft the rotatable tool is coupled, wherein the sensor elements are arranged on the support structure,
• wherein the support structure comprises a first subsection and a second subsection, and the first sensor element is a first connecting element between the first subsection and the second subsection, and the second sensor element is a second connecting element between the first subsection and the second subsection, wherein the first sensor element and the second sensor element are spaced apart from each other.
