Familiarity: I've used it several times
This thing is great, one side is the correct size for the screws that hold your bindings on the board, the other side is for all the screws on all the straps of your bindings. I use this at home even, when adjusting bindings. I wish I had a handier way to keep it instead of just flopping around at the bottom of my backpack, but that's not the tool's fault.
