What Is It? game 307

It's Thursday, so you know what it means, Neatoramanauts: it's time for the What Is It? Game, brought to you by the always amusing What Is It? Blog.

What are these things in the pictures? Your guess can win you a free T-shirt of your choice from the NeatoShop. Here's how to play:

Place your guess in the comment section below. One guess per comment, but you can enter as many guesses as you'd like in separate comments. Post no URLs or weblinks.

You might know what they are, but if you want to win a t-shirt, you'll have to use your imagination, because we are going to select two winners who give us the funniest incorrect guesses. If you guess right, then good for ya - but you don't win anything, mmkay? So, it's up to you, funny people: you have twice the chance of winning that T-shirt now.

Please write your T-shirt selection alongside your guess. If you don't include a selection, you forfeit the prize. We highly suggest you take a look at the NeatoShop's new selection of Funny T-shirts and Science T-Shirts.

Ready? Go for it! (Don't forget to visit the What Is It? Blog for more clues!)

Update: the mystery object is a cork borer sharpener. "A cork borer, often used in a chemistry or biology laboratory, is a metal tool for cutting a hole in a cork or rubber stopper to insert glass tubing." And this thing sharpens it. That was weird, but y'all came up with even weirder answers. A t-shirt goes to Kevin George, who said it is a "Radial doughnut cutter." Makes perfect sense. Another t-shirt goes to Jaguarfeather, who said "Tis a lawless switchblade peg-leg belongin' ter Captain Kidd's Kid. He were so short, nobody ere noticed him much, but iff'n ever a pirate be less than kind to the little bilge rat, the Kid took 'is satisfaction direct out of 'is ankle, he did!" Congratulations to the winners, and a big thank you to the What Is It blog, where you can find the answers to all this week's mystery items.
