What Is It? game 236

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?

Update: the mystery item is a rope winder from a hardware store, it was expanded to the appropriate size and then rope was wrapped around it, the parts were then collapsed and the customer was left with a coil of rope. The first correct answer came from anonymous coward, who requested a donation to an animal shelter in lieu of a t-shirt. There were a lot of wonderful funny answers (you should read them all), but the prize for that goes to Phil and Buster, who said this is a tool for centering the hole in donuts. That's worth a t-shirt from the NeatoShop! Thanks to everyone who played, and check out the answers to all of this week's mystery objects at the What Is It? blog.
