Abstract
A folding knife having a movable locking element that locks the blade in open position and retains the blade in secure closed position within an integrated spaced parallel monolithic handle frame member. A spring-urged locking retainment arm engages corresponding parallel portions of the blade shank when in respective locked open and locked closed positions. Sliding longitudinal displacement of the retainment arm allows for progressive engaged rotation of the blade shank about a pivot mounting point to a fully closed and locked position against two blade shank engagement points by the locking arm.
