A utility tool device including a handle with a tool recess and a lever arm recess; a rotatable lever arm with a magnet that is configured to fit in the lever arm recess; and a rotatable lever hinge attached to the lever arm and configured to attach to a tool; wherein the tool recess is configured to have a tool fit in the tool recess; and wherein the magnet is configured to lock a tool in place when the lever arm is in the lever arm recess.

A utility knife, a blade member for use therewith, and a method of using the same; The knife has an ergonomically designed, symmetrical handle with resilient grips for a user's palm and fingers provided on opposing top and bottom walls of the housing. The blade member has two opposed cutting surfaces aligned with the housings top and bottom walls. A tape engagement clip is provided on a leading end of the knife and secures a free end of a measuring tape to the knife. The knife may be gripped and used in two different orientations located 180 degrees apart. The tape engagement clip pivots to enable the free end of the measuring tape to be secured to the knife regardless of which cutting surface is used to cut an article. Alternatively, the clip may be moved to the opposing side wall of the knife.

The present invention relates to a cutting device, and more particularly to a cutting device having a selectively replaceable and reorientable blade. The cutting device has 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 also has a cutting member that is removably disposable and reorientable in the carriage and a cover member that is removably attachable to the housing.

The utility knife assembly includes a housing which extends in a longitudinal direction between opposite ends and presents an at least partially open interior. A blade with a sharp edge is fixed with the housing such that the blade extends through one of the longitudinal ends, and the blade is fixed with the housing in such a manner that it is non-movable relative to the housing. A blade protector is partially disposed in the open interior of the housing and is movable in the longitudinal direction relative to the housing between a retracted position and a covering position. In the retracted position, the sharp edge of the blade outside of the housing is exposed for cutting, and in the covering position, the sharp edge of the blade outside of the housing is covered by the blade protector.

Embodiments include a knife with an ideal blade length to weight ratio, with a body configured to save weight over known designs to achieve the ideal ratio. The weight savings to obtain the ideal ratio can be obtained by various space and weight savings features of the handle and its contained action mechanism, allowing the handle to be manufactured with a slimmer profile, but without sacrificing the rigidity of the action or handle. The slimmer and lighter handle allows a longer blade but without the increased weight resulting from a bulkier handle typically necessitated by a longer blade.

A utility instrument is in the form of a cutting tool suitable for fitting onto a user's finger. The tool has a blade and a sheath, both coupled to a mounting structure. The blade and sheath are pivotable with respect to each other. A user can wear the tool on a finger about a finger joint. The user can bend the finger to set the tool to an open condition to expose the blade for use, and can stretching the finger to set the tool to a closed condition to safely shade the blade using the sheath. The tool may further have a housing for fully receiving the blade. The blade may extend out of the housing for use, and may be retracted into the housing for safety.
