Prismatic blade
http://dbpedia.org/resource/Prismatic_blade an entity of type: Software
In archaeology, a prismatic blade is a long, narrow, specialized stone flake tool with a sharp edge, like a small razor blade. Prismatic blades are flaked from stone cores through pressure flaking or direct percussion. This process results in a very standardized finished tool and waste assemblage. The most famous and most prevalent prismatic blade material is obsidian, as obsidian use was widespread in Mesoamerica, though chert, flint, and chalcedony blades are not uncommon. The term is generally restricted to Mesoamerican archaeology, although some examples are found in the Old World, for example in a Minoan grave in Crete.

Prismatic blades were used for cutting and scraping, and have been reshaped into other tool types, such as projectile points and awls.
