What Is It? game 168

It is once again time for our collaboration with the always amusing What Is It? Blog. Do you know what this thing is? Can you give us a wild guess?

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 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?

Be sure to check out the What Is It? Blog. Let your imagination run wild, and good luck!

Update: Abbey had the correct answer in the very first comment -this is a hand-forged key. Scroll down the answer page to find out more. Galen gets the award for the funniest answer: Chuck Norris' mustache comb! Both will get t-shirts from the NeatoShop.
