MicroBlade

Microblade is a term used in different fields to refer to very small blades or bladelets. In archaeology, a microblade is a small, sharp lithic blade produced by pressure flaking from a narrow core. Microblade technology, often called microlithic technology, uses these bladelets as components of composite tools such as knives, scrapers, or projectile inserts. Microblades are typically small and finely worked; they occur in many regions from the late Pleistocene to the early Holocene and are associated with hunter-gatherer groups in Africa, Eurasia, and the Americas. The term can refer to the individual bladelets as well as the toolkit built around them, including hafted implements and projectiles.

In cosmetics, "microblade" commonly refers to microblading, a semi-permanent cosmetic tattooing method used to enhance the appearance of the eyebrows. A technician uses a handheld tool or machine equipped with fine blades or needles to create numerous hair-like incisions in the epidermis, into which pigment is deposited. The result is an appearance of natural eyebrow hairs and typically lasts one to three years, depending on skin type and care. Microblading requires trained professionals to minimize risks, and potential complications include infection, allergic reactions, scarring, pigment fading, and asymmetry. Aftercare is advised to support proper healing.

Outside these contexts, the term is rarely used; when it appears, it generally denotes very small blades or bladelets appropriate to the specific specialized application.
