1. A sensor system comprising:
a cutter element for a cutting tool;
an interrogation transceiver operable to transmit a radio-frequency (RF) interrogation signal; and
a sensor transceiver system operable to receive the RF interrogation signal and to transmit an RF response signal;
the sensor transceiver system including a signal guide medium configured to transduce between the RF interrogation signal, a guided signal in the signal guide medium, and the RF response signal;
a characteristic of the RF response signal being dependent upon a condition of the signal guide medium; wherein

the cutter element includes the signal guide medium to allow the condition of the signal guide medium to depend upon a condition of the cutter element proximate the signal guide medium; and
the signal guide medium is operable to backscatter the RF interrogation signal as the RF response signal.
