Hibukurahagi

The Hibukurahagi is a refined style of wooden joinery traditionally used in Japanese carpentry. 

Like other intricate grain-matched edge joining techniques, it involves carefully cutting a series of overlapping tabs along the edges of boards to be joined together securely. 

However, rather than the stair-stepped tabs of a chigaihagi joint, the Hibukurahagi is characterized by smoothly curving the individual tabs in long sweeps along the wood grain. 

Through meticulous planning and precision woodcarving, each flowing tab is cut to both follow and interconnect with the grain of the adjacent board. When fitted precisely, the curved overlapping "leaves" reinforce one another like an interlocking puzzle. Though small and delicate, the joint gains ample strength from the uninterrupted wood grain winding continuously around the seam. Demonstrating virtuosity in joinery, the Hibukurahagi fuses components seamlessly at their edges through elegantly curved grain-matched joinery alone, requiring no adhesives or mechanical fasteners. It serves as both a practical and artistic union of wood, exhibiting mastery of traditional Japanese woodworking craft.
