Yes, the round and crescent blade are from the bottom of a beer bottle.
The crescent blade shape is known to the Great basin region.

To be able to produce a "chip", a lot of pressure is placed against the knapping tool with finger tips and knuckles heading straight into the edge when the chip releases. No alcohol is involved when doing this or regular knifemaking around here, too much at risk.

Very impressive work!
