What Is It? Game 142

From Bob Roger's Collection

W00t! It's time for another collaboration with the always-excellent What Is It? Blog. Can you guess what this strange object is used for?

Place your guess in the comment section. One guess per comment, though you can enter as many guesses as you'd like. Please do not post any web link or URL - doing so will void your entry. You have until the answer is revealed on the What Is It? Blog tomorrow.

Two prizes: the first correct guess and the funniest yet wrong one will win a T-Shirt from the NeatoShop. IMPORTANT: Please write your prize selection alongside your guess, so visit the NeatoShop and take a look around. If you don't write your prize selection, then you don't get the prize.

For more clues, go to What Is It? Blog. Good luck!

Update 6/25/10 - Time's up! The answer is: An ice cube crusher, the patent states:

...it is proposed to arrange the containers telescopically relative to each other and to provide a plurality of pointed elements mounted on the top and base wall of the containers and directed towards each other for cracking a piece of ice placed within the containers when they are forced together.

Patent number 2,147,394

No one got it exactly right, but Clarence would've gotten it if he had just followed the instruction and selected a prize. The second prize goes to e7c who suggested scarification tool for Sneeches (complete with rhymes that would make Dr. Seuss proud!)
