- This cylindrical metal stainless steel rod is about 8" long and resembles a crochet hook. The metal is serrated along the middle part of the rod. One end is hooked, the other is flattened and U-shaped. The donor worked with tabulating machines and then computer equipment from the 1940s into at least the 1960s.
- Reportedly the hook was used to line up punched cards and the flattened end to complete holes that had not punched properly.
