ABSTRACT:
A combination chisel and punch for using one tool as a handle while striking another tool is provided. The combination tool includes multiple tool members with a striking end for being struck by another object and a working end for engaging a work piece. The tool members are pivotally connected by a link. A locking mechanism secures one tool member, serving as a handle, in an orientation parallel to the link while the user strikes another tool member, serving as a tool. When not in use, each tool member folds into an unlocked position for compact storage.
