20110289783 | APPARATUS AND METHOD FOR PROVIDING A HAND-HELD INSTRUMENT WITH AT LEAST ONE SELECTIVELY OPERABLE RETRACTABLE PROTECTIVE ELEMENT - The present invention is directed to a hand-held instrument, which may comprise, in various exemplary embodiments thereof, a folding (manual, assisted opening, automatic, etc,) knife, a fixed blade knife, or any other hand-held tool comprising a handle, and at least one active region (e.g., a cutting, a saw blade, etc.), and which also advantageously comprises at least one novel user-operable protective element, that when placed, by the user, into an active position that is generally perpendicular to the handle of the instrument, is configured for protecting at least a portion of the user's hand while the instrument is held and/or utilized, and that when placed into a retracted position that is generally parallel to the handle of the instrument, streamlines the instruments longitudinal profile. In accordance with the present invention, the inventive apparatus is advantageously provided with at least one actuating element selectively operable by the user, that when activated, causes a corresponding at least one protective element to automatically extend into the active position. In an alternate embodiment of the present invention, in which the novel instrument comprises an automatic opening blade that exists a predefined region within the handle thereof in response to the user's activation of an opening element, the novel instrument is advantageously provided with an actuating mechanism connected to at least one protective element that is operable to automatically cause the at least one protective element to extend into its active position in conjunction with the blade's automatic opening movement. | 12-01-2011 |
20120110858 | Safety Cutter with Blade Change/Storage Mechanism - A cutter apparatus includes a housing and a blade holder coupled to the housing, wherein the housing includes a distal portion (e.g., a blade storage compartment) that is both slidably and pivotally coupled to portions of the housing and configured to serve as a cover for the blade holder. The cutter apparatus can also include a cover release device configured to facilitate repositioning the cover between a locked position at which the cover is secured to the housing and a released position at which at least a portion of the cover is free to pivotally reposition away from the housing providing access to the blade holder. | 05-10-2012 |
20120210584 | SHIELDED KNIFE AND ASSOCIATED METHODS - A shielded knife includes a base, a blade secured to the base at a first end and a guard operatively attached to the blade at a second end opposite the base. The guard may be rotated between a closed position covering a sharpened edge of the blade and an opened position exposing the sharpened edge of the blade. | 08-23-2012 |
20130086808 | Utility Knife - A utility knife includes a handle, a blade assembly secured to the handle, a blade cover mechanically coupled to the handle facilitating manipulability of the blade cover to an extended position over the blade assembly, and a slider that is repositionable along the handle to release the blade cover from the extended position, the slider being pivotally coupled to the blade assembly. | 04-11-2013 |
20130180114 | FOLDABLE CHISEL - A chisel includes a blade and a first handle and second handle that are each rotatably coupled to the blade. The first handle forms a first channel adapted to receive a first side of the blade and the second handle forms a second channel adapted to receive a second side of the blade opposite the first side. The two handles are rotatable between an open and a closed position. In some cases, the two handles comprise a rotatable coupling such that the first handle and the second handle rotate with one another in opposite directions between the closed and open positions. The chisel further can have an over-center structure configured to impede rotation of the two handles from the closed toward the open position. In some cases, the two handles each form an interlocking component adapted to releasably couple the two handles when they are rotated to the open position. | 07-18-2013 |
