kamatsugi 鎌継
KEY WORD : architecture / joints
A gooseneck tenon and mortise joint. The mortise is cut into one section, and the tenon, with head and neck a single member, is cut into the other. The neck of the tenon is roughly square or rectangular and varies in length according to need. Kamatsugi were used as early as the 7c. By the medieval period, the head was tapered and resembled a blunted arrow. A variation resembling a double gooseneck with heads at each end of the tenon is set into the mortise of the same shape. Usually used to connect two beams. The joint is called *chigiritsugi 千切継.
