What Is It? game 187

Once again, it's time for our collaboration with the always amusing What Is It? Blog. Do you know what the pictured item is? Can you make 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?

Update: The item in question is a tool that was used to make cavities in bullet molds during the Civil War, sometimes called a bullet mold cherry. Electronix and Winslow both knew the answer. One was a little earlier; the other was more specific, so we are giving t-shirts to both of them! The funniest answer came from rob, who said,"It happens to be part of an ancient game. Originally called Paleolithic Roulette, it's played much like today's version of Russian Roulette. It is spinned (like a dreidel) and whoever it lands on gets the pointed side rammed into their temporal lobe." For that, he also wins a t-shirt!
