Abstract
A knife has a hollow body, a blade movable longitudinally on the body between an extended position projecting from the body and a retracted position substantially wholly contained within the body, a biasing element engaged between the body and the blade for urging the blade into the retracted position. A latch device is transversely engageable with the body in a latched position for holding the blade in the extended position and is out of engagement with the body in a release position permitting the biasing element to draw the blade into the retracted position. An electronic circuit in the body including a microelectronic accelerometer generates an output when the body is subjected to an acceleration exceeding a predetermined acceleration threshold. An actuator between the circuit and the latch puts the latch means in the release position when the detector generates the output.
