a blade having a tip, a tang portion, the tang portion having an end opposite the tip and a tang side surface, the tang side surface having a recess;

a first handle side being bifurcated by a longitudinally extended slot into a first portion and a spring locking portion, the slot having an open end and a closed end opposite the open end, the spring locking portion of the first handle side having a spring locking end adjacent to the open end of the slot and a wear pin disposed in the spring locking end, the wear pin extending beyond the spring locking end and slightly below a plane of the spring locking portion and toward the blade, when closed the wear pin springably slides into the recess of the tank thereby maintain the closed position, and when the blade of the folding knife is rotated to the open position, the wear pin slides under the end of the tank thereby locking the blade in the open position;

a second handle side; and

a pivot bolt extending through the first portion of the first handle side proximate the open end of the slot, through the tang portion of the blade, and through the second handle side allowing the blade to pivot at the tang portion, the blade is parallel to the first handle side and the second handle side;

wherein the spring locking portion is biased toward the blade such that when the blade is rotated to a closed position, the spring locking portion is springably disposed in the recess of the tang, and to open the folding knife, the blade is rotated such that the spring locking end springably slides under the end of the tang thereby locking the blade in an open position.
