What Is It? game 269

The question is: what is it? It's time for our collaboration with the fascinating What Is It? Blog! Do you know what the object in this picture is? You can win even if you don't know!

Place 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 each win a 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?

Check out the What Is It? Blog for more clues and pictures of the mystery object. Good luck!

Update: the pictured tool is a spoke wrench, suitable for holding pieces of wire or as a spoke-grip for screwing up the spokes of suspension wheels, such as are used in bicycles and other light vehicles. Steve Pauk knew what it was, and wins a t-shirt from the NeatoShop! The funniest answer of the week was from Paul D., who said it was a Higgs Boson. We've been looking all over for that, haven't we? Paul also wins a t-shirt from the NeatoShop! Thanks to all who participated, even if you just gave a heart. See the answers to all the mystery items of the week at the What is It? blog.
