Names: Gear tool, nut key (if you're Northern)
Who carries one: Leader, seconds
Use: A gear tool is used to remove gear that has been placed in a rock after the leader has finished climbing (or during if they've placed something wrong!)
How to use: Gear tools can be hooked underneath nuts to lever them out or can be used to hit nuts from below (ouch!). If something's really stuck, be inventive!
