In my day I've owned a couple sets of handcuffs. Some of them were kiddie era playtoys others real law enforcement equipment and I didn't dwell on them or get all kinky though you might think I certainly would.
Today is National Handcuff Day. It is observed on February 20 annually corresponding to the day one George A Carney was issued a patent in the United States for his "lightweight and adjustable swinging bow ratchet-type handcuff" which were developed in 1912.
In these days I'm way too low key to get all restrictive and entrapping with my play pretties. I think it all stems from a couple of incidents in my youth which went entirely too far.
Be all this as it may handcuffs are useful accessories for the agent of law enforcement or adventurous lover in your midst. I wouldn't go for the FROU FROU gold ones like I had. They draw too much attention and gain you ridicule after the fact.
Unless, of course you have the chutzpa to SMASH in the best traditions of the incredible hulk.
