Apart from the obvious use of arrows for what they are made for,in a survival situation a arrow or four
Could be tied around a straight branch and used as a thrusting spear
And that could be used to reach up high and cut fruit from a tree,with the sharp broadheads.
Hollow alloy arrows could be used as a straw to get at small pools of water in cracks in rocks
A hollow arrow may work as a close range blow gun on a small rat or something maybe,
