20150158187 | FOLDING KNIFE WITH DOUBLE DEPRESSION BLADE OPENING MECHANISM - A folding knife is provided that has at least two opening features on a blade of the folding knife. These opening features reduce the likelihood of injury when a user opens the folding knife and improve the effectiveness of the folding knife These opening features may be depressions, protrusions, or any other opening feature that aids the user and are positioned generally near the distal end of the blade. | 06-11-2015 |
20150151408 | Rotatable Hand-Held Blade-Sharpening Apparatus - 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. | 06-04-2015 |
20150128426 | Folding Knife with a Two-Piece Backlock - A locking mechanism for a folding knife is provided. More specifically, the locking mechanism is a two-piece backlock that maintains the folding knife's extended position and prevents the blade from inadvertently closing when the knife is in use in the extended position and impedes the folding knife from inadvertently opening when the knife is in a closed position of storage. The locking mechanism generally comprises a backlock, a toggle, and a biasing member. The toggle rotates between two positions and engages with the tang of the blade and the backlock. | 05-14-2015 |
20140154963 | Rotatable Hand-Held Blade-Sharpening Apparatus - 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. | 06-05-2014 |
20130305541 | Split Spring Locking Feature for a Folding Tool - 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. | 11-21-2013 |
20130283621 | LOCKING MECHANISM FOR A PUSH BUTTON ACTIVATED FOLDING TOOL - 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. | 10-31-2013 |
20130283620 | MODULAR SPRING ASSEMBLY FOR A FOLDING TOOL - 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. | 10-31-2013 |
20100083507 | Folding Knife Locking Mechanism With Carrier Device - 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. | 04-08-2010 |
20090142127 | WRITING INSTRUMENT WITH ROTATABLE HANDLES - 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. | 06-04-2009 |
20090140456 | Writing Instrument With Rotatable Handles and Method for Making the Same - 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. 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. A method of manufacturing the writing instrument by injection molding is also disclosed. | 06-04-2009 |
20080295337 | BI-FOLD KNIFE WITH LOCKING AND RELEASE MECHANISMS - 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. | 12-04-2008 |
