Butterfly joint
From Wikipedia, the free encyclopedia
A Butterfly joint is a type of joint used either to hold two or more boards together or to keep two halves of a board that have already started to split from splitting further.
A butterfly joint resembles two dovetails connected at the narrow part. A negative of the hole is cut out of the board the butterfly will be placed in and the butterfly is then fitted, keeping the joint together. The wood used for the butterfly is usually a contrasting wood, often walnut.
Butterfly joints are common in the work of George Nakashima.
