Hand-forged Japanese Joinery Knife: Kanawa Tsugi 金輪継

After a lot of trial and error i’ve felt confident in showing my process for making these Japanese Joinery based knives. Making a Kanawa-Tsugi joint on this micro scale is well... somewhat complicated. In western terms the joint translates to a half-blind tenoned, dadoed, and rabbeted scarf joint. The joint is carefully measured and adjusted slightly against traditional ratios/angles in order to compensate for the small scale. It’s a joint that is typically used for joining beams together by timber framers in Japan. I’ve made a few of these knives now and they are all holding up well but with this variation I’ve opted to stabilize the handle with G-Flex epoxy resin in order to deter any moisture or material degradation. This keeps the handle rigid and allows me to drill the holes for the hidden knife tang without potentially loosening the wedges. I’m happy to answer any question regarding the process. and now onto the steel: This santoku/gyuto hybrid
