ABSTRACT:
A collapsible chopping spade comprises a shaft with a tool joint at one end and a handle joint at the other end so that both the tool and the handle can be folded against the shaft. A unitary locking arrangement is provided for securing the handle in either its operative or its folded away position and for securing the tool in either of two operative positions or in its folded away position, the arrangement being such that the handle joint cannot be locked with simultaneously locking the tool joint.
