I must have been around 14 years old 1972-73 when my friend was using his old timer 34ot to loosen a phillips head screw and broke the tip. I was horrified and decided then to get a multi tool for just such a chore.
I got a decent one from the hardware store that was the pliers style in a nylon sheath. It was about 4 inches folded and had a knife blade, screw drivers and opener. Kinda clunky but It came in handy many times over a couple years before I lost it. Even a cheap multi tool is better than using a good pocket knife for screws, prying or opening a tin can.
