At Mystic Seaport today in CT, and they were talking about the heads used on whale harpoons. The pics below are from a mechanical design in the late 1800's. it's goal was to make as small an entrance hole, and then stay inside. Thought it was pretty neat.
Apparently it was based on an old Inuit design, only it pivoted when it was retracted.
