Abstract: A locking mechanism for a tool or knife blade based on the locking liner lock. A hinge replaces the typical flex point at the base of the lockbar which allows the lockbar to be made of materials other than those required to be resilient. This allows materials that are lightweight, non metallic, and many other possibilities. As well very strong non resilient materials can be used which would avoid some of the mechanical failures that resilient materials have shown by bending due to downward force on the top of the tool or knife. This mechanical failure will not only destroy the ability of a knife to lock in the open position but the event will cause the blade to rotate toward the closed position and can cut the operators hand. That is a safety issue.
