Abstract: A sharpening apparatus is provided. The sharpening apparatus includes a foldable case, a first sharpening tool, and a second sharpening tool. The first and second sharpening tools are associated with the foldable case and are rotatable between a storage position and a sharpening position.

Abstract: A folding tool with improved locking features is provided. The locking feature comprises a substantially rigid member disposed between or proximal to a handle portion of the tool. The substantially rigid member comprises a bifurcated end forming at least one biased member for contacting a tang of the tool and securing the tool in at least one of a closed and an open position with additional locking features.

Abstract: A modular spring assembly configured for interconnection with a folding tool is provided. The modular spring assembly may be positioned coaxially with a pivot axis of the folding tool and interconnected to the folding tool. In one embodiment, the modular spring assembly includes a cup and a torsion spring.

Abstract: A folding tool with an improved locking mechanism is provided. The locking mechanism generally comprises a biasing member interconnected to a handle of the tool and coupled to an engagement member, which may be a push button. In various embodiments, the biasing member biases the engagement member towards a locked position in which a portion of the engagement member interacts with a tang of an implement to prevent rotation of the implement.

Abstract: A writing instrument comprising a writing utensil and associated handles interconnected to each other to allow a user to selectively position the writing utensil in either an extended position of use or a closed position of storage, as well as a variety of positions there between. In an open position, the handles may be positioned adjacent one another with the writing utensil extended longitudinally away from the adjacent handles in a position of use. In a closed position, the handles may be positioned adjacent to the longitudinal length of the writing utensil, with the writing utensil at least partially enclosed between the handles in a position of storage. The rotation of the handles about the writing utensil allows a user to manipulate the handles in a variety of ways, similar to that of a “butterfly knife” or similar device comprising balisong style openings.

Abstract: A hand-held instrument comprising a writing utensil and associated handles interconnected to each other to allow a user to selectively position the writing utensil in either an extended position of use or a closed position of storage, as well as a variety of positions there between. The writing utensil may take a variety of forms, and the handles may incorporate additional devices or tools. The rotation of the handles about the writing utensil allows a user to manipulate the handles in a variety of ways, similar to that of a “butterfly knife” or similar device comprising balisong style openings. In one aspect of the invention, the writing instrument may be used to perform moves or tricks as a novelty device to provide entertainment and enjoyment to a user.

Abstract: A folding knife locking mechanism is provided which maintains the open and closed positions associated with the folding knife. A carrier assembly for the locking mechanism for changing the folding knife from the closed to the open position is also disclosed. In one embodiment, the folding knife comprises a carrier assembly for positioning a spherical locking mechanism against the tang of the knife, without the need for scales or other retaining elements typical in prior art knives.

Abstract: A bi-fold knife locking mechanism is provided which maintains the open and closed positions associated with the bi-fold knife. A locking and release mechanism for changing the bi-fold knife from the closed to the open position is also disclosed. An aperture in the blade portion of the bi-fold knife for ergonomically gripping the bi-fold knife is also disclosed. A locking plate for securing the locking and release mechanism and bi-fold knife in the closed position is also disclosed.

Abstract: The present invention relates to folding knives and implements, and more specifically to a locking mechanism used to prevent the inadvertent closing of the knife blade as well as overextension of the knife blade during use.

Abstract: This invention relates to folding knives, and more particularly folding knives which have locking mechanisms which engage the knife blade to prevent the inadvertent closing of the knife blade.

Abstract: A multi-purpose self defense tool is provided which can be used for pinching an opponent, delivering a blow and/or as a kinetic opening folding knife by positioning a pointed hump located on the non-cutting edge of the blade against an object or the body of an opponent and dragging the tool in a rapid motion.

Abstract: A folding knife locking mechanism is provided which prevents the inadvertent closure of a knife blade by utilizing a releasable tang which is compressed between the heel end of the folding knife blade and a stop pin.
