A utility knife is provided, including: a housing, defining an operation compartment and a storage compartment; a blade holder, movably received within the operation compartment; a blade storing carrier, movably received within the storage compartment, including a receiving portion for receiving at least one spare blade and a grip portion; and a locking mechanism, including a base body, a movable member, a first engaging member and a second engaging member, the base body being disposed to the housing, the movable member being attached to the base body and movable between a locking position and a release position, the first engaging member being disposed on and movable with the movable member, the first engaging member and the second engaging member are releasably engaged with each other so that the blade storing carrier is detachable from the housing.

A utility knife includes a blade, a housing to store the blade, an actuator, and a pinion gear to deploy the blade. The pinion gear includes one or more sets of teeth that are engaged with a fixed rack of the housing and a sliding rack of the blade holder. The pinion gear is also coupled to the actuator, which is configured to linearly translate the pinion gear. As the pinion gear linearly translates between front and back ends of the housing, the pinion gear rotates due to its engagement with the fixed rack. The further engagement between the pinion gear and the sliding rack causes the sliding rack to advance in the same linear direction as the pinion gear by a distance that is greater than the linear distance traversed by the pinion gear, thereby advancing or retracting the blade connected to the blade holder.

Some embodiments of the present disclosure provide a knife. The knife includes a handle and a blade, the handle includes a first casing and a second casing that are detachably connected, the blade is clamped between the first casing and the second casing, the blade is provided with a plurality of limiting openings that are arranged horizontally, a limiting structure corresponding to the limiting openings is arranged on the handle, and the limiting structure has a locking position and an unlocking position; when the limiting structure is in the locking position, the blade is fixed on the handle; and when the limiting structure is in the unlocking position, the blade can move forward or backward relative to the handle.

The present disclosure generally relates to a cutting device, and more particularly to a cutting device having a selectively replaceable and reorientable blade. The cutting device may have a housing and a carriage that is movably disposed in the housing, the carriage being movable between a retracted position and an extended position. The cutting device may also have a cutting member that is removably disposable and reorientable in the carriage and a cover member that is removably attachable to the housing. Further, the cutting device may include an adjustable blade depth assembly providing the ability to direct and/or pre-select the depth or length a blade disposed in the blade carriage will reach upon engagement of a dial component and/or switch member operably connected to the blade carriage.

The present disclosure generally relates to a cutting device, and more particularly to a cutting device having a selectively replaceable and reorientable blade.

The cutting device may also have a cutting member that is removably disposable and reorientable in the carriage and a cover member that is removably attachable to the housing.

A utility knife including a handle, a blade, a first blade holder, and a spare blade holder. The spare blade holder is pivotal with respect to the handle between an open position where the recess is exposed to allow a spare blade to be removed from the spare blade holder and a closed position where the recess is within a slot of the handle to inhibit removal of the spare blade from the spare blade holder. The spare blade holder further including a cam surface and the cam surface of the spare blade holder engages a cam surface of the handle when the spare blade holder is in the closed position to urge the spare blade holder in a direction from a first longitudinal side of the handle toward a second longitudinal side of the handle to allow the first blade holder to pivot between extended and folded positions.

A utility knife is disclosed, including a housing having a handle portion and a front end. A first wing and a second wing are each pivotally engaged with the handle portion. The first wing and the second wing guide at least one blade along an edge of a box when cutting and disassembling the box. A trigger extends and retract the at least one blade such that the blade(s) are only extended during use to protect the user.

A blade retention mechanism that includes a body and a catch. The catch is configured to engage a bit. A knurled nut is configured to engage the catch and the body such that it is movable. When the nut is moved between a first position and a second position the catch moves between a first position and a second position. A v-groove is formed in the body and is configured to receive and retain a bit when the catch is in the first position.

A utility knife includes a body having a front end and a rear end opposite the front end. A blade holder, supported by the body, is moveable relative to the body, to move a blade between an extended position and a retracted position. The blade extends through a blade aperture when in the extended position. The blade aperture is sized to receive a hook attached to the blade of a tape measure.

The present invention generally relates to a compact utility cutter. Specifically, embodiments of the present invention relate to an everyday use compact utility knife apparatus with a retractable blade. Embodiments of the compact utility knife apparatus are further comprised of a thumb slider switch configured to control the position of the blade.
