What Is It? game 231

Once again, it's time for our collaboration with the always amusing What Is It? Blog! Do you know what the object in this picture is? You can win even if you don't know!

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 each win a 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?

Check out the What Is It? Blog for another picture of the backside of this mystery thing. Good luck!

Update: the scary-looking object in question is a chainsaw bumper spike, or dog bumper. It attaches to a chain saw and is held against a tree to help steady the saw while it cuts. Read more about it at the What Is It? blog. The first correct answer came from Berhard, who wins a t-shirt! The funniest answer came from Colin M, who said it was a "megalodonometer."

That’s obviously a tool used be a Ichthyologist, they use it to measure the size of a sharks teeth, but only when they are still in the sharks mouth, hence the reason for the two bolt holes, which is used to mount to a stick, cause I do not know a Marine Biologist that would put their hand inside a sharks mouth.

That's good enough for a t-shirt from the NeatoShop! Thanks to everyone who played this week, and thanks to the What Is It? blog.
