Prismatic Blade

In archaeology, a prismatic blade is a long, narrow, specialized lithic flake with parallel margins. Prismatic blades are removed from polyhedral blade cores through pressure reduction. This process results in a very standardized finished tool and waste assemblage. While the prismatic blade industry is most often associated with obsidian (especially in Pre-Columbian Mesoamerica), it is not limited to that material; chert, flint, and chalcedony blades are not uncommon.
