Definitely a skill that decays quickly if you don't practice it. I don't do lockout calls so I always find I'm super rusty whenever I actually need to pick things for customers.
Locks especially high security ones like Medeco. I am the most knowledge person about them at the locksmith company I work at which easily puts me above the average Lemmy user.
Keys, wallet, phone, pick set (licensed locksmith and it comes in handy), pocket knife. Usually leave the last 2 at home if I am planning on going to anything with security checks.
