Abstract: An ax has an elongated socket extending along the top of the ax head in parallel relationship with the top of the ax blade. A detachable implement, which may be a spade blade, a pick point, a saw blade or any of various other implements, has a tang which is fitted into the socket to fasten the implement to the ax head. A spring biased latch pin, disposed in a passage in the ax head, has a first end that extends into an opening in the implement tang and an opposite end that protrudes from the the base of the ax head to enable retraction of the pin and replacement of the implement with a different implement. The socket is preferably open at both ends with the latch pin being midway between the ends enabling entry of an implement tang from either of two opposite directions to accommodate to reversible implements such as a combination hoe and rake blade.
