The Lost Art of Aztec Prismatic Blades
Start talking about flintknapping, and most people probably think of arrowheads or other projectile points. Though made using essentially the same fundamental techniques, a “prismatic blade” is a very different animal. In the archaeological record, prismatic blades appear as long, thin flakes of stone, usually having two parallel cutting edges and a trapezoidal or triangular cross-section. A few modern flintknappers make prismatic blades, but the leading light (online, at least) is probably Californian Jim Winn, aka paleomanjim.
