The present invention provides a power-assisted folding knife, including: a blade holder; a blade arranged in the blade holder; a handle rotatably connected to the blade holder; a locking mechanism for locking the blade holder in an unfolded position and/or a folded position; the power-assisted folding knife further includes a power-assisting mechanism connected to the blade holder and the handle, for providing assisting power when unfolding a power-assisted folding knife. The power-assisted folding knife in the present invention uses an assisting mechanism for providing assisting power when unfolding a folding knife, so as to facilitate easier unfolding of the folding knife and to allow single hand operation; the blade holder can be locked in an unfolded position and/or a folded position to ensure safe use of the power-assisted folding knife.

The handheld cutting tool variants disclose improvements to the handheld cutting tool of U.S. Pat. No. 11,426,888B1/application Ser. No. 17/704,935. The handheld cutting tool variants deploying a razor blade have enhanced cutting made possible by either modifying portions or eliminating portions of the blade holder nosing which in turn is made possible by deploying either one of two newly disclosed blade restraint mechanisms. As with application Ser. No. 17/704,935/U.S. Pat. No. 11,426,888-B1, the tool is comprised predominantly of a handle body, a blade holder assembly which serves to deploy and constrain a replaceable blade and a rotational control assembly actuated by the user that enables the blade holder to rotate between retracted and a plurality of extended positions.

Present embodiments related to a filet knife. More specifically, but without limitation, the present embodiments relate to a folding filet knife which is moveable between an extended position and a folded position. The blade has a length that is greater than the length of the handle. The filet knife has a handle with a second structure, for example a clip that can receive a portion of the blade that extends beyond the handle when the blade is in the folded position.

A folding knife apparatus including a blade portion; and a handle portion including a flexing plate connected to a base portion; and a piece. The blade portion may be connected to the handle portion so that the blade portion can rotate with respect to the handle portion when the flexing plate is in alignment with the base portion; and wherein the piece is configured to be placed in a state which prevents the flexing plate of the handle portion from moving into alignment with the base portion, and thereby prevents the blade portion from rotating with respect to the handle portion. The piece may have a J-shaped portion, at least a part of which is inserted between the flexing plate and the base portion of the handle portion to prevent the flexing plate of the handle portion from moving into alignment with the base portion of the handle portion.

A folding knife including a handle with a liner block with two parallel liners, defining a storage space between them. A blade pivotably mounted on the liner block with a pivoting axis engaged through the base of the blade and mounted on the liner block so that the blade can pivot between an inactive position, in which the blade is received in the storage space in the liner block, and an active position, in which the blade extends in line with the handle. A blade lock capable of blocking the blade in the active position.

A blade lock capable of blocking the blade in the active position.

A knife includes a blade, a first handle having pivotably coupled to the blade, a second handle pivotably coupled to the blade, the second distal end of the second handle defining a first locking mechanism and a second locking mechanism, a latch pivotably coupled to the second distal end portion and supporting a locking pin, the locking pin configured to selectively engage each of the first locking mechanism and the second locking mechanism separately, wherein the first handle and the second handle are each selectively repositionable between an open position and a closed position, wherein in the open position, the first handle and the second handle extend away from the blade, and wherein in the closed position, the first handle and the second handle extend along the blade.

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.
