He's probably only got the one for sale??????

The item description says more than 10 available and 9 sold. Just a guess but I'd say you're wrong.

Hello Ian:

It seems that somebody has coined your technique; these keys are all over the bay.

My hunch is that the thickness of the nickel is of some utility here. You would create a crevice along the edge and install a folding metallic protrusion with a right-angle tip. Is this essentially correct?

Regards,

Upon closer inspection I've noted a second small protrusion in tandem with the key bit that rotates about the outside of the keyway. This second bit acts as a guide pin of sorts, as the makeshift key doesn't rotate about the key post in the usual fashion.

With a very precise and flush mounting job, this nickel should be almost undiscernable from an ordinary one. A very clever concept, though no one really carries change in their back pocket, as the item description suggests. Having to reach around to a front pants pocket while handcuffed behind the back would be awkward and likely arouse suspicion from the captors. The nickel would be better placed in a loose-fitting jacket or overcoat pocket whereby it would be easier to access discreetly.
