A hand tool-typically embodied as a knife-incorporates a blade or implement lock mechanism for securely locking the implement such as a blade in the open position. The lock mechanism locks the blade in the open position and allows it to be released so that the blade may be folded back into the closed position. The locking mechanism incorporates a safety mechanism that prevents the blade engaging lock from becoming unintentionally disengaged.
