A dovetail piece is a type of joinery used in woodworking. It is created by cutting a set of pins and tails that interlock when fitted together. The pins are cut along the grain of the wood, while the tails are cut across the grain. A TENON is a type of joint that is used to connect two pieces of wood. It is created by cutting a rectangular or square projection on the end of one piece of wood, which is then inserted into a corresponding mortise cut into the other piece of wood.
