Gimlet (rocket) clip capable of fitting the internal rocket bays of the F4D Skyray interceptor was also developed. Following a flyoff against the T-214 rocket, which indicated the necessity to modify the rocket motor to reduce the Gimlet's visual signature, the Navy directed the development of a modified, 'hybrid' rocket, using the T-214's tail; this became known as "T-Gimlet". The modified rocket was considered to be suitable for the Navy's purposes; both the original Gimlet and the T-Gimlet were ordered for production, a 5 million dollar USD contract being allotted to start production at the Shumaker Naval Ammunition Depot in Arkansas.

Tool use by sea otters has significantly larger gluteus muscles than other mustelids. Sea otter forelimbs are small and not used in swimming. Forelimb structure, particularly musculature and skeletal anatomy, are potentially adapted for, "tactile sensitivity and tool use associated with detection, handling, and consumption of prey". The lower incisors of sea otters protrude and are shaped like spades, a shape which may facilitate their ability to scoop food out of shellfish. During consumption of sea urchins, otters use a tool or their paws to crack open the sea urchins and scoop out the gonads and viscera with the lower incisors (12). The canines are
