ABSTRACT:
Folding tools including a tool blade and a handle are foldably connected by a lockable hinge which permits folding the assembly for compact storage but automatically locks into a rigid assembly when fully unfolded. The hinge operates by the movement of a locking bar into locking groove(s) via a tensioning mechanism when the hinge components are aligned in the unfolded, extended configuration. The lockable hinges can be used to connect the blade and handle components of a variety of common tools including shovels, saws and the like, and are disclosed and claimed in Applicant's U.S. Pat. No. 6,588,240.
