West Shore Animal Clinic's Dr. Daniel Hebert took x-rays of the hafted shaft for the Cape Cod Museum of Natural History in Brewster, MA. The x-rays revealed that the windings of the binding are probably not made from plant fiber threads, as was previously thought. Dr. Dan's x-rays are currently on display at the museum.
