lancets

Lancets are small, sharp instruments used primarily in medical settings for making incisions in the skin, typically for blood sample collection or to puncture the skin for testing purposes, such as monitoring blood glucose levels. They are designed for single use to ensure hygiene and prevent infection. The tip of a lancet is usually very pointed, allowing for a quick and precise puncture. In a broader context, the term "lancet" also refers to a style of pointed arch in architecture, or a thin, tapered design in various fields.
