Where is a butt joint most commonly used?

A butt joint is most commonly used in woodworking and construction, where two pieces of material are joined end-to-end or edge-to-edge without overlapping. This type of joint is frequently found in framing, cabinetry, and furniture making, as well as in drywall installation. Its simplicity makes it easy to create, although it may require additional reinforcement, such as screws or adhesives, for added strength.
