@settinger @MLE_online @zcopley Ohhhhh, yes. The clip fastening at the top would sometimes go if you were too heavy-handed unfastening it to change balls, but usually it was the teeth. I was almost a regular at the IBM shop! (It was only a bus ride away, so it was easier for me to go in my lunch break and get a new golfball immediately, rather than having to order one & wait.)
