Claim 2:
3. A tool comprising a resistor and a writable and/or readable data storage device arranged in a shaft region of the tool for identifying a working end of the tool, wherein the resistor is configured to identify the working end of the tool and the writable and/or readable data storage device is configured to store data related to the working end of the tool in at least a first memory area, and wherein the resistor and the writable and/or readable data storage device are arranged to provide the data related to the working end of the tool in an externally detectable manner for recognizing the working end of the tool, wherein the resistor and the writable and/or readable data storage device are integrated as a unit into the tool and connectable to an external control device via an electrical contact in the shaft region;
wherein the shaft region of the tool comprises a proximal end for insertion into a handle or handpiece and a distal end comprising the working end of the tool;
wherein the electrical contact is located at the proximal end of the shaft region on the outside of the tool; and
wherein the tool further comprises a conductor that extends from the proximal end to the resistor and the writable and/or readable data storage device.
