Some time ago I picked up a magazine called 'Primitive Archer', which was about making your own bows and arrows in the wilderness the way a paleolithic 'cave man' might have done it. One of the articles was about 'flint knapping', which is the stone age practice of hitting a rock with another rock, to get a knife edge or shape.

This technique can me used to make arrow heads, hand-axes, and knives out of rocks that you find...by using other rocks. I did try to do this in an anthropology class in High school once. It takes a lot of practice and a lot of time in order to do it right...but it's about as 'bare bones' as you can get.

I don't know about making something 'sword like' such as a machete in the wilderness without using tools. I guess you would have to experiment on your own. Perhaps if you cut a machete blade out of the side of a large tin (such as something olive oil for a restaurant might come from), then bend one edge over to give it a back, then sharpen the 'blade' edge. You'd have to come up with a safe 'handle' part to hold...which could be done by wrapping the handle part with twine/ tape, I suppose. Make a 'T' bar shape at the end, so that the twine/tape doesn't slip off. This 'tin can' machete might be a little flimsy and dangerous to use, so I think your best bet would be to fold the tin over and over, hammering it on something flat and anvil-like. Either that or insert something into the 'back' of the machete. Depending on your definition of 'wilderness', you could always go dumpster diving for something suitable.

All the "Hoods Woods" videos are excellent.
