Abstract
An improvement of a folding knife locking mechanism with an adjustable wedge to remove blade slop. The present mechanism allows for smooth opening and closing of the blade by limiting friction against the blade as it rotates. This knife has a bearing system for low friction blade rotation. Also the leaf strap lock is arranged so that it only comes into contact with the blade at the start of opening and at the end of opening, further limiting the friction forces against the blade. Provided is also an adjustment wedge to remove blade lock slop. In the manufacturing process loose tolerances can be adjusted out using the adjustment wedge. Normal use wear against the stop pins and handles can cause some looseness of the blade which can also be removed by the adjustment wedge.
