Microblade technology is a period of technological microlith development marked by the creation and use of small stone blades, which are produced by chipping silica-rich stones like chert, quartz, or obsidian. Blades are a specialized type of lithic flake that are at least twice as long as they are wide.[1] An alternate method of defining blades focuses on production features, including parallel lateral edges and dorsal scars, a lack of cortex, a prepared platform with a broad angle, and a proximal bulb of percussion.[2] Microblades are generally less than 50 mm long in their finished state.[3]
