ABSTRACT:
The folding tool of this invention has first and second jaw structures which are pivotable with respect to each other into an out of operative engagement with each other. A first handle portion and a support plate and second handle pivot with respect to the jaw structures about substantially the same axis. The first handle portion and the support plate can be rotated with respect to the jaw structures so that the jaw structures are supported therebetween (the closed position), and also to a position where the jaw structures extend away from both the first handle portion and the support plate (the open position). In the open position, two springs on the support plate each engage a respective jaw structure. One of these springs springingly locks one of the jaw structures in the open position with respect to the support portion. The other spring engages a camming surface on the other jaw structure which biases the jaw structures apart, i.e., away from engagement with each other. The springs also serve to springingly secure the jaw structures between the support portion and the first handle in the closed position, so that the tool, when folded, is relatively compact and does not open inadvertently.
