Yay! Today's the day for our collaboration with What is it? Blog. Can you guess what this strange tool is used for?
Place your guess in the comment section - one guess per comment, please, but you can submit as many as you can think of. Two prizes this week, folks, a free Neatorama T-shirt of your choosing: one for the first correct guess and one for the funniest but incorrect guess.
For more clues, check out the What is it? blog. Good luck (but if you don't win, you can still get Neatorama and artist-designed shirts in our online store!)Update 5/19/08 - the answer is:
A roller type cement jointer, also called a sidewalk groover, sidewalk creaser, or center knife; it's used to smooth the joint between two concrete surfaces.
Congratulations to CMart who got it right first, and to Mel Phistopheles for the funny but ultimately incorrect guess of butt crack creaser!
