ABSTRACT:
A hand tool according to the invention, such as a pair of snips, has a releasable locking mechanism whereby the jaws of the tool can be secured in a closed position. The locking mechanism includes a pair of projections disposed in offset, opposing positions on the handles of the tool. The projections have respective holes which are brought into alignment when the tool handles are brought together to close the jaws. A suitable mechanism, such as a rectactable button, engages both holes and holds the handles together against the force of a spring which biases the jaws towards an open position. The locking mechanism can include a groove-and-projection detent mechanism which allows the jaws to be unlocked by simply squeezing the handles.
