A safety cable cutter used for cutting a cable used in servicing an oil and gas well. A centrifugal arm roller and a guide roller are mounted on top of a frame. The cable is received on the rollers as the cable is lowered down a well bore. Mounted on ends of the centrifugal arm roller is a centrifugal arm attached to an arm coil spring. The coil spring holds the centrifugal arm next to the end of the roller. Opposite ends of a clamp attached to a cutter bar are slidably received in a pair of cutter bar guides. When the centrifugal arm roller exceeds a certain speed indicating a free fall of the cable, the bias force of the arm coil springs is overcome and the arms move outwardly. Contact ends of the arms engage the opposite ends of the clamp. The clamp and cutter bar are then moved outwardly and the cutter bar cuts the cable.
