Some hideout money, done that.

Paracord laces in boots, do that.

'Cuff key (on my keyring), yup, sentimental reasons. I still have a few pairs of cuffs, just in case, but don't carry them on me anymore.

Lock picks, nope, not since I retired. In CA, and probably other states, they are considered burgular tools in the hands of anyone except a licensed locksmith or LEO...
