Reguarding the Ax thing...

Good ones are expensive, some can be had very inexpensively at swapmeets or yard sales if they require some minor work. they might need a new handle(haft) or the edge may need some work. Some smaller sizes like a "boys ax", tomahawk or hatchet could prove invaluable if you need to process wood for fires, make stakes for tarp lines or set poles for a latrine.

My point is you do not need 10-20 of a specific tool, 3-4 of anything when loaned to the right individuals to make something happen is very amazing. if you do get some of the same types some spare handles is also a good idea, as in; "if you break it bring it back so (you or) I can fix it."

Or possibly some bow saws would cover the wood processing.

Very cool topic you brought up. Lots of good responses.
