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.

A multipurpose outdoor tool having a handle and an ax head at one end thereof, said tool further having means for optionally fastening an auxiliary tool implement to said ax head, said auxilary implement having a tang for engaging said ax head which tang has an opening therein and said ax head having a socket for receiving said tang, wherein the improvement comprises: said ax head having an interior passage which extends from said socket to an exterior surface of said ax head, further including a movable latch pin extending within said passage, said latch pin being slidable along said passage between first and second positions at each of which at least a portion of said latch pin remains within said passage, and wherein said latch pin has a first end which extends into said socket when said latch pin is at said first position and which enters said tang opening when a tang is seated in the socket and said latch pin is at said first position, said latch pin being retractable from said socket by sliding of said latch pin towards said second position to enable withdrawal of said tang, further including means for limiting axial movement of said latch pin to movement between said first and second positions thereof which means prevents inadvertent separation of said latch pin and said ax head.
