Abstract
A folding knife including a handle, a pivot axis, and a blade having a cutting edge. The blade is pivotably coupled to the handle such that the blade is pivotable relative to the handle about the pivot axis between a retracted position and an extended position. The cutting edge is exposed in the extended position and a portion of the blade is received within the handle in the retracted position. The folding knife further includes a bearing assembly for facilitating movement of the blade between the retracted position and the extended position. The bearing assembly includes a first bearing recessed within the blade and a second bearing recessed within the handle.

A folding knife comprising:
- a handle comprising a first handle and a second handle coupled to the first handle;
- a blade having a cutting edge, the blade is pivotably coupled to the handle between the first handle and the second handle, the blade is pivotable about a pivot axis with respect to the first handle and the second handle between a retracted position and an extended position, the cutting edge is exposed in the extended position and a portion of the blade is received between the first handle and the second handle in the retracted position;
- and
- a groove within the blade, the groove extending around the pivot axis;
- a bearing within the groove for facilitating movement of the blade between the retracted position and the extended position, the groove comprising a recessed surface facing towards the first handle, the bearing comprising a disc-shaped bearing cage, the disc-shaped bearing cage comprising a lateral surface that faces towards the first handle and away from the recessed surface;
- and
- a stem that extends longitudinally along the pivot axis, the stem comprising an outer planar portion facing away from the pivot axis, and the outer planar portion of the stem is received within an aperture of the second handle and an aperture of the disc-shaped bearing cage.
