Abstract: A folding assembly having first and second members that are pivotally attached to one another. A locking pin is disposed through the first member and second member and selectively actuatable to unlock the pivoting and opening or closing of the first and second members relative to one another. A spring-assist mechanism includes a primary spring element and a secondary spring element which act in conjunction to successively apply an opening force to the first or second member as it is opened. The assembly also includes a close-assist mechanism for partially closing the first and second members relative to one another.

Abstract: A knife sheath assembly that secures and protects a knife when subjected to harsh or rigorous conditions. The knife sheath assembly includes shims which add durability to the sheath assembly. The components of the sheath assembly are connected in such a way so as to allow broken or damaged parts to be replaced.

Abstract: A folding assembly includes a tool pivotally connected to a handle and movable between a closed position in which the tool extends along the handle and an open position in which a free end of the tool extends away from the handle. A manually actuated locking mechanism includes a locking pin extending axially through an elongated slot of the tool and into a track of the handle. A spring is disposed within the elongated slot of the tool that biases the locking pin away from the free end of the tool. A portion of the locking pin travels a length of the track as the tool is moved between the closed and open positions.
