A question. Been knocking out a few points lately and rolling through thoughts on the variety of materials one sees (flint, obsidian, bone, agate, petrified wood, glass, etc). Would heavy duty clam shells be suitable for knapping smaller points? Being 7 hours from our Oregon coast, I don't have any on hand to break up? Don't know if they would fracture predictably or not.
Also wondering if sharks teeth were ever employed?
Salmonella: Thanks for posting those picks. Will have to give that museum a look when I get down that way. Lots of design ideas in those pics. Looks like if someone could think of it someone hammered one out.
