What is it/are they?

Does anybody recognize what these metal items are? They range from about 3" long to 6" long as shown but are adjustable for extra length. There are no inscriptions on any of them. The previous owner used to design and fit prosthetic devices to vets, but I don't know if these are related to that job.
