Abstract: Various embodiments of a folding knife are disclosed. In one embodiment, the folding knife includes a handle, a blade including a tip and a tang with the tang having a tang block engagement element, an axle pivotably connecting the blade to the handle, and a lock mechanism. The lock mechanism includes a locking block constrained to move along a fore-aft linear axis, the locking block including a lower engagement surface, an upper engagement surface, and a rear surface. The lock mechanism also includes a biasing device carrier pivotably connected to the handle, a biasing device oriented between the biasing device carrier and the rear surface of the locking block and the biasing device configured to bias the locking block toward the blade tip when the blade is in an open orientation, and at least one handle block engagement element oriented above the upper engagement surface of the locking block.

Abstract: Various embodiments of a folding knife are disclosed. In one embodiment, a folding knife is provided that has a handle having a slot having at least one top surface and a blade pivotably connected to the handle, wherein the blade has a tang having a contoured peripheral surface and an open block engagement tang surface, wherein the blade has an axis of rotation. The blade further has a locking block translatable on a plane orthogonal to the axis of rotation of the blade, wherein the locking block has an engagement surface positioned to contact at least one of the contoured peripheral surface and the open block engagement tang surface when the blade is in an open position, and wherein the locking block has at least two bearing surfaces engaging the at least one top surface along two lines.

Abstract: A folding knife having a blade locking member carried for sliding movement within a channel defined in the handle, the locking member being movable to a blade locking position when the blade is in an extended position. A spring, or other biasing means, such as an opposing magnet arrangement, provide a spring-like biasing of the locking member towards a blade locking. In one embodiment, the locking member extends substantially the full width of the handle and is accessible from either side of the knife handle. The locking member includes a ramp on the underside thereof for contacting a projection, or bump, on the rearward portion of the blade tang. An adjustable bushing is provided which allows for adjustment of the blade within the handle to provide for both ease of pivoting of the blade, while reducing any lateral play in the blade within the handle.
