Description
Inspired by the work of Good Guy Biker, I created a covert handcuff key for your everyday carry (EDC) with Thinkedcad.
This covert handcuff key requires NO SUPPORT and takes only 15 minutes to print…
TESTED & WORKS ON: Smith & Wesson and Peerless Handcuffs
The clip from the handcuff key allows it to be securely fixed to clothing.
Discreet placement options include behind the belt loop, waistband of pants or underwear, top of sock, shoelaces or coat laces or even the cuff of a long-sleeve shirt,etc. Its small size and low-profile design make detection extremely unlikely, yet it's always accessible when required in case of emergency.
