Well using a hacksaw blade I've cut out spear, arrow and knife shaped material from discarded oil cans and car bodies and then used a file to sharpen the edge(s)...They worked Ok.

I've been interested in knapping either flint or obsidian for years and had even taken a short weekend course on how to do it and the items I've made, while serviceable, are nowhere near pretty.

Using the same knowledge you can turn glass pop bottle bottoms into very serviceable points and I made an Ulu shaped skinner from a large bottle that I was very proud of--worked very well skinning caribou until I stepped on it by accident which I then made into two arrow points.

I've lashed them to arrows made of reeds and spears from saplings and well as fire hardening the sapling to make a digging spear.

I've also used fresh water clam shells as skinners of rabbits, deer and fish and the edges are extremely sharp and stay sharp for a long time.

Of course there are always the clubs that can be made utilizing a rock and if shaped can be effective axes as well...I did make a bolo with three river rocks tied with babiche (moose guts or sinew) to some thongs of moosehide but never snagged anything with them.
