Mortises can be created using any choice or combination of a drill or drill press, chisels, or a router. Tenons are often cut onto the end of a rail can also be made with many hand saws, table saws, routers or chisels. Most mortise and tenon joints are square or in shape, but round peg shapes are also common.
