Utilities and how to use them

Abstract

A utility tool in the form of a cutting tool adapted to fit on a user's finger. The knife has a blade and a sheath, both coupled to a mounting structure. The blade and scabbard are pivotable relative to each other. The user can wear the knife near the knuckle of the finger. The user can bend the finger to set the knife into an open position to expose the blade for use, and the user can also stretch the finger to set the knife to a closed position to use the sheath to safely cover the blade. The knife may also have a housing for completely housing the blade. The blade is extendable from the housing for use and retractable into the housing for safety.

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application Serial No. 62 / 339,474, filed May 20, 2016. technical field [0003] The present invention relates generally to a utility tool and in particular to a hand tool for attachment to near a joint of an appendage, such as a finger or arm, and to be used by bending the appendage. Background technique [0004] Hand tools such as knives are known. Typically, a knife includes a handle for holding and a blade for cutting. The handle also acts as a scabbard to protect the blade and prevent accidental injury to the user. For example, retractable knives include handles that allow retractable blades to be moved in and out. The knife can be stowed by retracting the blade into the handle, and opened by extending the blade therefrom. In a collapsible knife, the handle includes a longitudinal groove, and the handle is rotatably coupled to the blade by a pivot....

Problems solved by technology

[0005] A disadvantage of opening and closing known knives is that their use requires manual operation of the associated closing mechanism

Although retractable knives typically require only one handed operation, the opening and closing action still requires holding the knife in one hand and using a finger, such as the thumb, to extend or retract the blade

Therefore, the user must remove anything held in one or both hands before opening or closing the knife, thus causing inconvenience and delay in work.

[0006] Another disadvantage of known knives is that the user has to remove the knives from his or her hands from time to time in order to perform other tasks

In addition, the user may forget where he or she left the knife and then need to look for it, causing inconvenience and work delays

Additionally, the user may accidentally drop the knife and the dropped knife could injure nearby persons and / or cause damage to nearby objects
