Abstract: A device for sharpening knives, comprising a frame and a grinding element rotatably mounted in the frame. The grinding element is provided with two cone-shaped grinding surfaces turned towards each other. The cone angle of the grinding surfaces varies in the peripheral direction of the grinding element, with at least one portion with a small cone angle having a rougher surface than the portion having a wide cone angle.
Abstract: The invention relates to a package for scissors, which package comprises a card (1), a case (3) for the blade portion of the scissors, and means (6) for fastening the scissors to the case. In known packages, the fastening means of the scissors are relatively complicated, and the fastening must be carried out manually or by means of a special machine. The fastening of the scissors (4) to the case (3) becomes simpler if the case is provided with snap action means (6) which can engage with a head (5) of the hinge member of the scissors. In order to enable the snap action of the means, the case is formed as a substantially stiff sheath (3) which can be used as a covering for the scissor blades during the later use of the scissors.
Abstract: A device for disengaging a wire loop or cable loop either when the hook (2) is unloaded or loaded, when, in the first case, only the locking pivot (9) is removed, or, in the second case, the load is moved onto a hydraulic system (8), whereafter the pivot (9) can be removed and disengagement takes place by discharging the pressure from the hydraulic system (8). After disengagement the hook (2) returns by itself to its original position and can instantly be relocked by the pivot (9) for reloading. Additional safety mechanism can be provided if necessary.
Abstract: A folding fillet knife comprises a molded two-piece plastic or metal handle, a metal blade pivotally connected to the handle and pivotable between open and closed positions, and a latching member slidably mounted on the handle. The latching member is spring biased into a latching position wherein it engages the base end of the blade and either releasably secures the blade in closed position or positively locks the blade in open position. The latching member is slidably movable to an unlatching position either automatically (as the blade opens) to enable the blade to be pivoted from closed to open position, or manually to allow the blade to be pivoted from open to closed position.
Abstract: A knife holder for removably supporting kitchen knives, each having a handle and a blade, is adapted to rest on a table or counter or hang on a wall. The holder includes an upwardly sloped upper surface, a generally vertical front surface, a plurality of slots extending inwardly from these two surfaces, and an obstruction near the lower end of the slots so that the length of the interior portion of a slot at least equals the length of a knife blade, whereas the frontal portion of a slot (down to the obstruction) is shorter than the knife blade. A knife handle engaging projection is located adjacent the upper end of each slot to prevent accidental slippage of a knife from a slot. When a knife is supported in a slot, the blade tip is behind and below the obstruction, and the knife handle rests on the upper surface of the holder behind the handle engaging projection.
Abstract: A flexible knife scabbard has a blade-receiving elongated passage open at one end extending longitudinally therein and has a blade sharpening slot open at both ends extending laterally therethrough and transversely through the elongated passage. Knife blade sharpening insert means including a pair of mating rigid plastic insert members or components are disposed in the elongated passage and each component includes an aperture in registry with the other and with the blade sharpening slot. The insert means further includes a pair of cylindrical ceramic blade sharpening elements or rods, one mounted on each insert component and overlying a portion of the associated aperture. The two rods are disposed in V-shaped arrangement relative to each other and located at (and overlapping) an end of the sharpening apertures in the insert member and the sheath slot. The knife blade slips into the scabbard between the insert members in normal use.
Abstract: A knife sharpener for sharpening kitchen knives and embodying coarse and fine sharpening devices is adapted to be hand-held during use or to be releasably mounted in a stationary position during use on a storage and mounting bracket which can be permanently attached to a supporting object such as a table, a counter or a wall. The knife sharpener comprises a handle, a head having two slots in which sharpening devices are mounted, a protective flange between the handle and head, and detent-engaging recess at the extreme outer ends of the handle and head. The storage and mounting bracket comprises a base plate, screw holes for attaching the bracket to a supporting object, upwardly projecting slightly flexible members at opposite ends of the base plate, and a detent on each upwardly projecting member for releasable engagement with an associated detent-engaging recess on the knife sharpener.
Abstract: A plastic sheath for protecting the blades of a pair of scissors being stored or carried comprises two elongated plastic members permanently secured together along a mating seam as by sonic weld to provide a pair of spaced apart side walls and a pair of edge walls which cooperate to define an elongated blade-receiving passage open at one end and extending along the longitudinal axis of the sheath. A blade-sharpening slot extends inwardly from one edge of the sheath transversely to the sheath axis and includes outer and inner interconnected offset slot portions. An elongated abrasive blade sharpening element is stationarily mounted inside the blade passage of the sheath and extends generally longitudinally of the sheath and intersects the blade sharpening slot between offset adjacent ends of the blade sharpening slot portions.
Abstract: A hand-held dual knife sharpener comprises a gripping portion and an adjacent sharpener portion embodying coarse and fine sharpening devices on opposite sides thereof. The sharpener portion has two blade-receiving slots extending inwardly from the opposite sides and a sharpening device is located near the bottom of each blade-receiving slot. Each sharpening device comprises a pair of elongated blade sharpening elements arranged in converging and overlapping relationship to each other so as to define a V-shaped groove. The sharpener is fabricated of a pair of molded plastic mating components which are secured together and between which the four sharpening elements are entrapped.
Abstract: A belt-mountable scabbard for carrying a sportsman's knife comprises spaced apart walls defining an elongated recess for receiving and protecting the blade of a knife carried in the scabbard. A knife blade sharpener is permanently mounted on the scabbard and comprises a blade-receiving sharpening slot formed in the scabbard and a pair of angularly arranged abrasive elements permanently attached to a wall of the scabbard near the sharpening slot for making sliding engagement with the edge of a knife blade being moved in the slot to effect sharpening.
