St Chaos You are looking at a covert polymer thumb dagger with a fully functioning break away handcuff key that can not be picked up by a metal detector. Enough said! Warning: Understand what you are purchasing and if you operate in environments where it is required. This is not a toy or collectible item. Stay Safe. Stay Legal.
You should know your handcuff actions before using polymer keys. If you overrotate the key to the double lock side expecting the cuff to open the key will break. Know your Cuffs or learn before attempting to use.
