Fist Lock looks like a fist but it's a padlock. It has four fold over hinged fingers that are held in place when the thumb is rotated into place and the key turned at the wrist.

When the key is used, an internal mechanism causes all of the fingers and thumb to lock in position.

To see what it looks like, make your left hand into a fist, then use your right hand to operate a can of aerosol paint to spray it a bronze metallic padlock colour.

Note - it's main use is for keeping rings safe which can be placed on the fingers before folding them over.

Now I think I’ll leave my left hand bronze. That should be good.
