Square Corner Joint

Detail: The square corner joint is a refined woodworking method that employs mortise and tenon connections to unite short wooden segments both vertically and horizontally, crafting an array of geometric designs. These include patterns reminiscent of the Chinese character "卍," grid-like formations, intersecting crosses, diamond shapes, and more. Crafting each segment demands meticulous precision for consistent mortises and tenons, adding complexity to the artisanal process. This joinery is frequently utilized in the ornamental facets of mahogany furniture—such as bed frames, chair backs, and cabinet lattices—where it serves as a fundamental decorative element.

Process: Square corner joints are typically crafted with either through tenons or blind tenons. Complex angular joints, such as the swastika-shaped ones found on Huanghuali step beds, showcase exquisite workmanship. Rather than employing straightforward angled cuts, these joints feature slender strips that conceal the end grain of the longer wood pieces, intersecting only at their tapered tips. The precision and care invested in fashioning these joints are remarkable, reflecting a considerable dedication to the craft.
