The term feather edge refers to a type of wood or board that is tapered to a thin edge on one side. This technique is commonly used in the construction of tabletops, cabinets, and other furniture pieces to create a seamless and stylish finish. The feather edge is achieved by carefully planing or shaping the wood, resulting in a curved or angled profile that gradually thins out towards one side. This technique is often employed to reduce the visual bulk of the furniture, enhance aesthetics, and create a sense of lightness. Edge of a board thinned off, as in paneling.
