A pin hinge is a traditional hinge style that rotates on a vertical axis maintained by a single pin. While pin and barrel hinges are commonly used for cabinetry doors, they can also be found on both interior and exterior doors. The pin hinge typically consists of two moving leaves wrapped around a pin. Full-sized doors often have removable pins, but cabinetry doors typically have smaller pins that are not easily removable and may bend if forced.

Cabinetry runs can be fitted with hidden hinges that only reveal the pin and barrel at the seam, creating a classic and affordable look. However, those seeking a more antiquated style may opt for pin hinges with decorative leaves that embellish the cabinetry seams. These hinges can be made from a variety of metals, but blackened iron is the best option for a subdued beauty that enhances without overpowering.
