My second handcuff (the first one is here).
With this one, I had a free hand in the design. I didn’t like the idea of a locking device, so this design is secure, but can be operated by the wearer.
When closing the handcuff, the left hand side as we see it, clicks into one of two positions and then the shield comes down to prevent the lugs from springing open. This is the reverse side as the other side has the hallmarks and, particularly, is stamped with the recipient’s name.
I’m pleased with this design!
