摘要： The present disclosure provides a knife sharpening device, including a housing and a sharpening assembly arranged inside the housing. The sharpening assembly includes a sharpening wheel rotatably mounted inside the housing. The sharpening wheel includes two opposite mounting surfaces arranged along an axial direction and a sharpening surface along a circumferential direction. The housing is formed thereon with a first sharpening groove that is arranged on a first side of the sharpening surface. The first sharpening groove is formed with openings at both ends along a length direction, and the first side of the sharpening surface extends partially into an interior of the first sharpening groove. During sharpening, a knife is placed into the first sharpening groove to contact the sharpening surface for grinding. According to the technical solution of the present disclosure, sharpening grooves are formed on the housing and fit with the sharpening surface.

摘要： Apparatus for sharpening a cutting tool. In some embodiments, a tool sharpener includes an abrasive medium having an abrasive surface. A stationary tool support guide provides a guide surface that supports a side of the tool during presentation of a cutting edge of the tool against the abrasive surface. A rotatable edge guide has a roller member with a curvilinearly extending outer surface. The roller member is rotatable about an edge guide roller axis to engage, via rolling contact, the cutting edge during the presentation of the cutting edge against the abrasive surface.

摘要： A blade sharpening and blade sharpness detection system for permitting blade sharpening and a determination of blade sharpness without mechanical contact with the blade cutting edge. An optical inspection unit inspects blade sharpness optically, and a blade positioning and guidance mechanism positions and guides the blade in relation to the optical inspection unit. An output display provides visual output of blade sharpness. The optical inspection unit, which can be a reflective optical sensor, and the blade positioning and guidance mechanism are retained by a pivotable support structure. The positioning and guidance mechanism can comprise first and second pairs of rotatable spheres, each such pair disposed in immediate juxtaposition to act as rolling supports for the blade. The entry of ambient light into the sharpness sensing volume can be prevented by resiliently deflectable light-blocking bodies retained to first and second sides of a sharpness inspection slot within the housing.

摘要： An automatic knife sharpening machine may include a vice to grip a blade of a knife and a pair of grind wheels to grind material from the blade. The machine may include a scanner to determine a profile of an edge of the blade, and a sharpness sensor to determine a sharpness level of the edge. The machine may include a controller. The controller may perform a first sharpening pass on the knife by moving the grind wheels into contact with the blade, and advancing the grind wheels longitudinally along the blade from adjacent the vice towards a tip of the blade with the grind wheels in contact with the blade. The controller may determine, using the sharpness sensor, the sharpness level of the edge after the first sharpening pass and perform at least one second sharpening pass when the determined sharpness level is less than a threshold sharpness level.

摘要： A clamping assembly includes a base defining a spring well. A spring piston assembly is received in the spring well and includes a spring and a piston body. First and second jaws are supported over the base on opposite sides of a central clamp axis that extends vertically through the spring piston and between the jaws, where the jaws are pivotable between an open position and a closed position. A wedge is movable along the central clamp axis between an end of the jaws. A lever has an elongated lever body extending to an end portion defining an L-shape with a toe and a heel, the end portion positioned between the wedge and the spring piston with the toe pivotably connected to the wedge and the heel coupled to the piston body via a linkage. The lever is operable to move the wedge along the central clamp axis.

摘要： A tool assembly is arranged for simultaneous treatment of both sides of the edge of a knife. The tool assembly comprises a tool in the form of a stave having faces extending longitudinally between first and second ends of the stave. A holder is provided in which the stave is journaled pivotally within a restricted pivot angle range (α) defined by a pivot limit function accomplished through interaction between the holder and the stave. A pivot journal means, for example, in the form of a pivot pin and a pinhole, is arranged for journaling the stave pivotally about a center axis of the stave.

摘要： The knife includes a handle and a blade, which is pivotably connectable with the handle and is able to pivot between an open position and a closed position. A cutting edge of the blade is fully disposed within a slot in the handle when the blade is in the closed position. Clippers are incorporated into the handle and include a first clipping piece, a second clipping piece, and a lever. The first and second clipping pieces have opposing clipping edges. The lever is configured to press one of the clipping pieces towards the other clipping piece to bring the clipping pieces together.

摘要： A grinding jig for holding a blade tool having an edge in a grinding machine. The grinding jig may have a first and a second clamp half arranged to hold between them at least a portion of a blade tool. An elongate support portion may support the grinding jig onto a support bar of a grinding machine. The elongate support portion may comprise a front end abutment surface and a rear end abutment surface. The front and rear end abutment surfaces may be spaced to receive a portion of a support bar such that the grinding jig may be moved back and forth relative to the support bar in a direction parallel with its longitudinal center axis.

摘要： Apparatus configured to sharpen a blade of a cutting tool. In some embodiments, a sharpener is provided having a housing and a sharpening stage with at least one sharpening element. Each sharpening element is characterized as a plate and has a curvilinearly extending, concave sharpening surface configured to impart a corresponding convex sharpening geometry to a selected side of the blade during a sharpening operation in which a user retracts the blade along a longitudinal drawing axis through the sharpening stage. A pair of intersecting sharpening elements may be provided to form a substantially v-shaped groove for a ripper-type sharpening stage. The sharpening element(s) may be fixed or tiltable with respect to the housing. The sharpening element(s) may further be moveable in a lateral direction to narrow or widen the v-shaped groove and change the convex geometry and edge angle imparted to the blade.
