Double Dovetail Tenon

Detail: The double dovetail tenon, often referred to as the wood butterfly joint or butterfly tenon, is a technique used to connect box panels or parallel rectangular wooden pieces. This method interlocks them via an up-and-down motion. It functions to both unite and strengthen the wood, with the finished joint resembling a pair of back-to-back dovetail tails, creating a trapezoidal outline upon connection.

Process: To assemble a double dovetail tenon, one begins by crafting the wider end of the tenon, then chisels out a matching mortise according to the tenon's dimensions. The tenon is then inserted into the mortise to complete the joint. Double dovetail tenons are commonly employed to reinforce tabletops and halt the progression of cracks. By fitting the tenons into the ends of a crack, they effectively fortify the tabletop and inhibit further damage.
