There are several exceptional flint knappers that make antique repros of older flint heads, look in Primative Archery Magazine, for ads. A fellow in Alabama, named Ray Griggs, is phenominal, and if you go to "Knapping" knap-ins, you can meet and collect modern made replicas. Most of the "arrow heads" found today, are Archaic spear, ataladyl?, or knive edges, not really arrow heads. The moderns are really good, shop around, you'll find some really beautifully made ones. Three Rivers Archery does have some nice heads, as does Pine Hollow Longbows, just shop a bit!
