Can you guess this tool? (Patreon)

Friends:

I love posting sneak peeks of upcoming Compass Rose releases. I take a pic from an odd angle and try to stump the Patrons. But my past experience with this game has humbled me. You guys figure it out nearly every time, even when I'm sure you can't possibly get it. You all guessed the Vise Block and that was a new invention!

So, with that in mind, here's a detail from our newest tool. Anyone care to guess?

Full video tomorrow.
