This briefcase didn’t just protect valuables — it fought back. In the early 1960s, engineers built a wild mechanical anti-theft briefcase that literally trapped anyone trying to steal it.

Just clever engineering and a bit of psychological warfare. The idea was simple: embarrass the thief and hold them long
