    摘要： An electrically powered knife sharpener for ceramic (or other brittle, crystalline or amorphous media which could be used for blades) knives includes at least one pre-sharpening stage with a sharpening member(s) and includes a final stage with a sharpening member(s). There are one or more motor driven shafts on which the abrasive surfaced sharpening members, such as disks, are mounted. Guide structure is provided to guide the knife for aligning and positioning the knife facet precisely at a defined location on the abrasive surface of each rotating sharpening member. The pre-sharpening stage sharpening member(s) moves in a first direction. The final stage sharpening member(s) moves in a second direction which differs from the first direction.

    摘要： A sharpener includes a motor driven shaft (3) with at least one slidably mounted sharpening assembly consisting of a supporting hub structure (6) mounted by its central bore hole on the shaft. The hub structure supports a symmetrically shaped rotating surface (2) containing an ultra fine abrasive material. The rotating surface is pressed with a force of less than 0.2 lb. by a spring action (8) to make sustained rotating abrading contact with a facet of a knife positioned by a knife guide to align the facet into contact with the surface containing the abrasive materials.

    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： A knife-edge conditioning apparatus comprises at least one precision angled knife guide (7) with one face (3) of the knife blade (1) maintained in sustained sliding or rolling contact and which guides the elongated edge of the blade into sustained contact with the hardened surface of an object (13) and positions the plane of the adjacent edge facet at a precise predetermined angle (B) relative to the contact plane (5) of the hardened surface (13) made of a material of equal or greater hardness than the metal of the knife blade without any tendency to abrade as the blade face (3) is moved along the guide (7) with its elongated edge in sustained contact with the hardened surface (13).
