I saw a review on the Master Lock Street Cuff, if the name is right. They look like handcuffs, and seem light and small enough to be usable as a light, sort of popping into a cafe to buy a Coke, type of lock. I don't want to transport heavy D-locks around, but neither do I want to leave my Gemini 1000 propped up against a wall while I go for Coke or a crap, if you understand where I'm coming from.
Anyone use these locks?
I'm also a little sensitive about being stopped with them in my possession, as someone else looking at them from a different angle might misinterpret what they are.
