Abstract: A guard for a folding knife which guard protects the fingers of the user when the blade is open. The guards may be lifted by the movement of the blade by a link, spring, lifting pin, gears, underside of the blade or hooked by thumb stud or back of blade or by a flipping motion due to the contour of the handles. The guards may be of various shapes and may be recessed in an out-of-the-way position when the blade is closed. The guards may extend at opposite sides of the blade and opposite sides of the handle. The guards are adaptable to a wide variety of folding knife styles.

Abstract: A locking mechanism for a folding knife. The locking mechanism has a locking sleeve and an opposed locking bolt which are coaxial and biased to a locking position by a spring. In the locked position, either with the blade extended or folded, both a lug on the bolt and a surface on the sleeve engage a locking surface on the blade tang area. Simultaneous manual force must be applied by the user to oppositely release buttons on the opposite handles to move both the locking bolt and locking sleeve to positions to disengage them from the locking surface to allow the blade to be folded or unfolded.

Abstract: An electrical box defining an electrical component enclosure for a device such as a receptacle, switch or wire for establishing connections. A wall of the box has mounting members, either flush or projecting above the surface, which mounting members define a bore for a nail or screw. The mounting means is exteriorly of the enclosure to comply with applicable codes. The bores are angularly oriented so an electrical fastener may install from the front of the box requiring a cut-out only slightly larger than the dimensions of the box. A fastener guide channel may be provided to assist to align the fastener with the bore when it is recessed. Preferably the box is fabricated by molding it from plastic such as phenolic material. The box may be round, square or rectangular.
