What is a collector, if not obsessive. Over the years I have sought out other media related to handcuffs and restraints.
What can I say, when it comes to going overboard - I try to lead. These animations were created in Adobe Dimensions. They attempt to display how the mechanism in some "typical" cuffs works. They do not accurately depict the process and shouldn't be taken as engineering drawings.
A picture of the cover, short review, and publisher information, for various books about handcuffs.
The satellite patent office in Sunnyvale, CA provided me with copies of some rather old and interesting patent papers.
