Yes, they make a padlock that opens with a common handcuff key (the handcuff key can be bought for less than a dollar).
Just seems kind of stupid. They could make it with a different shaped keyhole that looks like a regular wide keyway, but also fits a handcuff key. WHY NOT DO THAT?
You wouldnt want someone examining the padlock’s keyhole and easily deducing that a common handcuff key would open it, right?
