What Is It? game 337

Our friend Rob of the What Is It? Blog has been traveling, but he's back for a limited time, with more mystery items!

What is this thing in the picture? Your guess can win you a free T-shirt of your choice from the NeatoShop! Here's how to play:

Place your guess in the comment section below. One guess per comment, but you can enter as many guesses as you'd like in separate comments. You have until tomorrow afternoon to enter.

You might know what it is, but if you want to win a t-shirt, you'll have to use your imagination, because we are going to select two winners who give us the funniest incorrect guesses. If you guess right, then good for ya - but you don't win anything, okay? So, it's up to you, creative people: you have twice the chance of winning that T-shirt.

Please write your T-shirt selection alongside your guess. If you don't include a selection, you forfeit the prize. We highly suggest you take a look at the NeatoShop's new selection of Funny T-shirts and Science T-Shirts.

Ready? Go for it! (Don't forget to visit the What Is It? Blog for more clues!)

Update: This item is, indeed, a Morris scissor bench plane, or plow plane. You can see the patent application at the What Is It? blog. Several of you knew that, but as we said, we are giving away T-shirts from the NeatoShop for the funniest answers.

A t-shirt goes to canyourepeatthequestion for this gem:

Although incorrectly displayed laying on its side, it is still easily recognizable as a scissor lift for squirrels performing bird feeder "Maintenance". What appears to be a curved wooden handle is in fact the lateral stabilizer, stylized to resemble a squirrel's tail in the style of famed rodent lift designer Sir UpseeDaisy J Nutter. At auction, I would expect this piece to fetch at least three or four hundred acorns.

and to Berhard for his pun:

It is one of the classic "phrase causes":
If you worked with this pane-tool and placed on a chair and you forget about it... and you later sit down on exactly this chair, you instantly become aware that this tool is the reason for the phrase "pane in the ass"...

Thanks to everyone for playing along! We’ll do it again next week, for a limited run as long as Rob has items to identify at the What Is It? blog.
