>>166430Axe, Pot, Tarp.
I can wood drill, if I can't find a natural flint to spark against the axe, the axe will work acceptably at most knife tasks, will be very durable, and useful for shelter construction, etc. The tarp, because it makes it so easy to make a shade shelter, but the big thing is dew/rain collection. And the pot is for cooking and water storage.
If I were forced to take a person, I'd take the dumb bitch because she'd be easier to kill, and I don't see myself staying sane trapped on a small island with either of those personalities.
