Anyone make knap glass heads for big game? i was helping dig a basement and we uncovered some old broken bottle. i was knapping some yesterday.they knap pretty good. Anyone use glass ever? i made for small game but aint sure about deer.

Hillbilly:
I've knapped a good bit of glass, and wouldn't hesitate to use a well-made glass point as a serious hunting point. Manmade glass is pretty much identical to obsidian for all practical puposes. It's not as tough as most cherts, rhyolites, and such; but the first shot is the one that counts on an animal. If it hits a bone and breaks, the break is just exposing more razor-sharp edges.

wow thats nice. how to you get the roughness on it. mine is just a flat smooth piece of glass.

Hillbilly:
You have to run flakes all the way across it (or halfway from each side) to get rid of the flat original surface. You want your points to have a lenticular cross-section. That one was made from a flat piece of fenton/carrera glass that I found at an old dump site in the woods. It's really sharp stuff, I sliced my finger to the bone on a pressure flake from that point.

Woodland Roamer:
Yeah glass works great, is good practice and you can usaully find lots of it for free especially around old home sites or old trash dumps in the woods. That's a great looking point HB!
