Just to share an interesting story on how knowing about different locks came in handy

in my guitar class at school the teacher forgot the combination to the lock that held all the guitars in the closet. Luckily for me, my friend had a soda can. I chugged it and used my hands to rip it (no scisors) into a suitable shape to shim the lock. Yes, i had permission from the teacher who was quite impressed lol
