Our department places people who don't use gear in charge of ordering gear. Hinged handcuffs are mandated equipment due to their utility as a force option. (Don't get me started.) While I have had a set of hinged cuffs since I read Massad Ayoob's article on them in the early 1980's, I preferred chain cuffs. All of the retired real police used chain cuffs and the security academy other officers are sent teaches chain cuffs.
Anyone out there with a lesson plan n hinged handcuffs? Thanks and be safe.
