most of the points are heated central texas flint...the drill is texas flint which is somthing i never made before but i found its kinda tough to keep a nice center ridge....the black piece is a small piece of local ryolite caveman gave me it works real good but its tough also was my first time with ryolite...ended with a hinge in the center but hey maybe if i can knap more of this rock i can figure out how it likes to be hit...oh and the other rock is a biface out of some tenn or kentucky rock i am not sure what it is kinda knaps like chalk but in a good way i got that biface on my youtube channel if ya wanna check it out..thanks..made with direct moose billet-hammer stone-tine flaker
