What Is It? game 244

Once again, it's time for our collaboration with the always amusing What Is It? Blog. Can you tell us what this thing is? Or make a wild guess?

Give us your guess in the comment section below. One guess per comment, please, though you can enter as many as you'd like. Post no URLs or weblinks, as doing so will forfeit your entry. Two winners: the first correct guess and the funniest (albeit ultimately wrong) guess will win T-shirt from the NeatoShop.

Please write your T-shirt selection alongside your guess. If you don't include a selection, you forfeit the prize, okay? May we suggest the Science T-Shirt, Funny T-Shirt and Artist-Designed T-Shirts?

For a closer look, and some other mystery items, check out the What Is It? Blog.

Update: the mystery item is a billiard cue lock (you gotta pay if you wanna play). Anker had that one right, and wins a t-shirt from the NeatoShop!  The funniest answer cam from Malyss, who described a "manicure manacle:"

It is an extreme manicure manacle. Normally, you would find these in pairs and they would be bolted onto the arms of chairs at a nail salon. The person having the extreme manicure would place their wrists through the manacle and the salon associate would lock the customer's wrists into place before beginning the manicure.

That's good for a t-shirt, too! Thanks to everyone who played, and be sure to check out all the mystery items at the What Is It? blog.
