Awesome quartz points! It is such difficult material to work, that we rarely find any up my way that have serrations or notching, even though quartz is the most abundant material at the northern end of the Chesapeake Bay area. It seems the people who made the Guilford points liked the red and yellow quartz and quartzite a lot. Do you guys in SC & NC find many other style points made from the red/yellow quartz material, or is it mainly the guilfords?
