A bead is a woodworking decorative treatment applied to various elements of wooden furniture, boxes and other items.
A bead is typically a rounded shape cut into a square edge to soften the edge and provide some protection against splitting. Beads can be simple round shapes, or more complex patterns.
A bead may be created with an electric router, a special moulding handplane or a scratch stock. Beads are usually cut directly into the edge of the item to which the bead is being applied. However, beads applied across the grain are usually cut into a separate piece which is then fixed in position.
A bead is also an important design element in wood turning, a ring-shape or convex curve incised into a piece by the use of a chisel or skew.
