A dovetail joint or simply dovetail is a joinery technique most commonly used in woodworking joinery (carpentry) including furniture, cabinets, carcase construction, log buildings and traditional timber framing.
Noted for its resistance to being pulled apart (tensile strength), the dovetail joint is commonly used to join the sides of a drawer to the front. A series of pins cut to extend from the end of one board interlock with a series of tails cut into the end of another board. The pins and tails have a trapezoidal shape. Once glued, a wooden dovetail joint requires no mechanical fasteners.
Even though there are many tools that can simplify the process of building dovetails, you can get fantastic results doing them by hand.
