So I'm currently in the Boyle Estate party and people keep telling me to put my weapons away, but I've no idea how.
I've had a quick look through the controls to see if there is a way to bind a button, but there doesn't seem to be. It must be possible as after cutscenes your weapons are automatically sheathed.

To sheathe your weapons, hold the "Use" button. By default, this is F on the PC, ◻ on the PS3 and X on the Xbox 360 version.
