What was it called?

My family was sitting around talking, and somehow we started talking about those hand-held adders that people used to use at the grocery store to add as they shopped. It was shaped to fit in the hand with three buttons to click as you shopped to add your purchases. I know it isn't a vintage calculator or anything, but it is bothering us that none of us could remember what they were called. Can anybody help up solve a silly little mystery?
