Yup - it's one day early, but here it is: our weekly collaboration with What is it? blog. Do you know what this strange tool is used for?
Place your guess(es) in the comment section - one guess per comment, but you can enter as many as you can think of. Please post no URL (let others play). First person who guessed right will win a free Neatorama T-shirt! If no one got it right, then the funniest guess will win it instead.
Check out What is it? Blog for more clues. Good luck!Update 6/6/08 - The answer is: A lumberjack's log marking hammer, two more rows of numbers could be attached to the head. Congrats to Paul D. who got it right!
