Shitage Kama is a two-shouldered mortise and tenon with a half dovetail, double wedged in. I googled it and others have called it Stringer to Leg joint. Jay said that this is one of the strongest joints and one that he uses often. You can make a sawhorse with this joint. I’m nowhere near there, but I’m enjoying myself, focusing, messing up and learning. I want as many mistakes as I’ve made to be shown because they are evidence of my struggles, my perseverance and my experience. Oh. I’m not done! Still need to make the wedges.
