Making the "Impossible Joint" 四方鎌継

Making Shihou Kama Tsugi (four-way goose neck joint). When you first look at it, it can be confusing as this joinery is on all four sides, without a way to be taken apart. But this joinery actually slides diagonally, making this "illusion" possible. The wood is Walnut and Birch.
