Got home from work and lit the kero heater in the barn and did some knappin. Got these three done in a couple of hours. I broke two, but kept @ it. Not pretty, but OK. I'm happy w/ em.
The first on is cortex I think, but it's sharp. 88grains. the second is a local material the old indian guy @ the museum gave me, coocky notches, was longer too, 134 grain, and the whitish one I found the material in the pit and had a hit, 128 grain. Thanks for looking. dpgratz
