There are several common traditional wood joints that I use depending on the application, including dovetails, mortise and tenons, sliding dovetails, bridle joints, and the occasional decorative scarf joint. I use wood joinery exclusively in my furniture, as opposed to metal fasteners, because the technique has demonstrated its utility for long term stability. Using screws and brackets is surely much faster and can work fine for a few years but because of the fluctuations wood seasonally experiences rigid metal elements eventually work free and you end up with a wobbly chair or cabinet. Wood joints on the other hand are designed to cycle together so that they are always size matched. This synchronicity produces a stable and a very strong joint for the long term. There is of course the pure visual appeal of wood joints as well. Few can pass by a finely dovetailed drawer without taking notice and perhaps running a finger along the joint to feel the smooth union of surfaces.
