摘要： A cutting tool, such as a kitchen knife, has a handle with an outer grip surface. A blade extends from a distal end of the handle along a central axis. The blade is formed of a metal material and has opposing first and second side surfaces that converge to a cutting edge having a plurality of continuous segments separated by a series of spaced-apart channels. Each channel is formed by an interior sidewall that extends into a body portion of the blade from the first side surface to the second side surface. Each of the channels has a channel width extending in a direction along the cutting edge, and a channel depth orthogonal to the channel width. The channels are formed using a cold forging operation on the first side surface to provide localized work hardened portions of the metal material adjacent the respective channels.

摘要： Device for sharpening blades of cutting-off machines, comprising two grinding wheels (1) each positioned on a corresponding side of a cutting edge (20) of a blade (2) of a cutting machine. The device comprises means adapted for controlling the symmetry of said cutting edge (20), with a sensor (3) placed at a predetermined distance from a corresponding side of the cutting edge (20. The sensor (3) is adapted to detect possible differences (d) between the lengths (n, p) of the two sides of the cutting edge (20). The sensor (3) is connected to a programmable unit (4) that processes the said difference (d) possibly detected by the sensor (3).

摘要： A portable sharpening apparatus is described. The sharpening apparatus includes a body portion and a cavity formed in the body portion for receiving an object to be sharpened. A rotatable abrasive drum capable of sharpening and having an axis of rotation is provided and the abrasive drum is located in the body portion. The apparatus further comprises a motor arranged to drive the abrasive drum and a mouth communicating with the abrasive drum and arranged in the body portion so as to direct an object to be sharpened towards the abrasive drum, wherein the mouth has a supporting means for locating an object to be sharpened at the abrasive drum, the supporting means being such that, when in use, an object to be sharpened is orientated along an axis substantially perpendicular to the axis of rotation of the abrasive drum.

摘要： A grinding wheel for treatment of a cutting edge, such as a knife's edge, the grinding wheel arranged mountable on a rotatable shaft to be brought in rotation by the driven rotation of the shaft, and comprising two grinding discs (1>2) opposing each other and arranged movable relative to each other in the shaft's longitudinal direction and pre-tensioned away from one another, each of the grinding discs having a hub section (8) with fingers (9) protruding freely from the hub section at a radial and an axial component of direction, wherein the fingers are arranged at intervals dimensioned for passage of the corresponding fingers of the opposite grinding disc such that the finger's axial components of direction together form an outwardly open, in an axial cross- sectional plane generally V-shaped notch (V) defined by the intersecting rotational planes of the crosswise running fingers, and in which the fingers each has an area (11) for treatment of the knife's edge. The V-shaped notch has an insertion region (I) in which the width of the notch (B) in the axial plane is greater at the leading edge of the finger than the corresponding width (B2) at the trailing edge of the finger, as seen in the direction of rotation of the grinding wheel.

摘要： A wide range of knives and blades, including Western, Asian or traditional Japanese style blades that have a primary edge facet on at least one side of the knife edge are sharpened through use of an electric knife sharpener having a first sharpening stage with at least one rotating abrasive surface disk and a knife angle guide to position the blade's facet at a first relative angle of approximately 15 degrees as it contacts the moving abrasive surface. The knife sharpener includes a second sharpening stage with at least one rotating abrasive surfaced disk and a knife angle guide to position the blade's facet at a second relative angle of approximately 20 degrees as it contacts the rotating abrasive surface. The knife sharpener also has a third stropping stage with at least one rotating stropping disk containing abrasive particles of less than 1 thousandth of inch diameter and a knife angle guide to position the blade's facet at a third relative angle larger than the first and second angles as it contacts the rotating surface of the stropping disk. The rotating sharpening and stropping disks are displaceable from a rest position against specific restraining forces when contacted by the edge facet being sharpened or stropped.

摘要： An electric abrasive sharpener for sharpening edges having pairs of interlocking abrasive wheels formed with opposite abrasive helical threads. Each end of the threads respectively has lead-in section and lead-out section having chamfer edge portion to eliminate kickback. The abrasive wheels of the sharpener is driven by a single phase AC motor connected to a motor drive that steps down the rotational speed of the output shaft of the motor to rotate the abrasive wheels with increased torque.
