Abstract: A container assembly for a sharpening stone which can be converted from a package for transport and display into a pedestal for supporting and exposing the sharpening stone for use. The assembly is formed of a sheet of polymeric material having a plurality of panels joined by living hinges. A generally box-shaped package can be formed for containing the sharpening stone by folding the panels in one direction and joining end flaps and panels by the use of detents. A pedestal for exposing the sharpening stone can be formed by folding the respective panels on the assembly in the opposite direction and joining into a box-shaped configuration with the use of the end flaps, panels and detents.

Abstract: Apparatus for manually sharpening dental instruments which require honing at a specific angle, comprising a planar base member having flat parallel sides and an elongated slot, a planar honing stone having flat parallel honing surfaces disposed within the slot of the base member perpendicularly to the plane of the base member and a spring clip positioned between one end of the slot and the honing stone for providing a biasing force to maintain the honing stone in pressure contact with the other end of the base member slot.

Abstract: In order to achieve precision in sharpening, particularly for dental instruments, a sharpening device includes a base having a generally upwardly extending hand grip portion wherein the base is adapted to be position on a generally horizontal supporting surface. The sharpening device also includes a sharpening stone or the like operatively associated with the base together with a retainer for removably retaining the sharpening stone in at least one angular position relative to the generally horizontal supporting surface. Further, a method of sharpening a dental instrument having a cutting edge defined by a face and lateral side is disclosed. The sharpening method includes providing a support for a sharpening stone at a preselected angle to a horizontal plane and then holding the dental instrument with one hand while also holding the support with the other hand.

Abstract: A blade sharpening device is convertible between a sharpening configuration and a storage configuration. The device has an elongated body with a lower surface for resting on a support surface and an upper surface with a pair of receiving holes disposed thereon. Each of the receiving holes receives one elongated abrasive sharpening member so that the members can be supported in a V-shaped sharpening pattern when the device is in its sharpening configuration. The body also has a pair of elongated storage chambers extending along the longitudinal length of the body. Each of the storage chambers has an opening disposed on one end of the body. Each of the storage chambers receives one of the sharpening members through its respective opening when the device is in its storage configuration. A cover is pivotally secured to the body at an intermediate location and has an open position corresponding to the sharpening configuration and a closed position corresponding to the storage configuration.

Abstract: The blade sharpening device is an adjustable multi-angle edge sharpening unit comprised of a base connected to a rotatable sharpening stone table and a vertically adjustable blade support table. A hand movable sharpening stone is positioned on the sharpening stone table and the blade to be sharpened positioned on the blade support table, with the blade in grinding contact with the sharpening stone. An angle selection chart on the base allows vertical movement of the blade support table in conjunction with rotational adjustment of the sharpening stone table to accurately select a specific angle at which the blade edge is ground. A scissors adapter unit may be attached to the blade support table which permits the sharpening of scissors blades. The scissors blade is pressed against the scissors adapter, the blade being in grinding contact with the sharpening stone in much the same manner as knife blades are sharpened by the device.

Abstract: A sharpener which has a main body portion to hold and support a sharpening stone 1. The main body is connected at one of its ends to a front guide plate and on the opposite end to a back guide plate. These two plates, in addition to guiding the direction of a knife blade during sharpening, also act to hold the stone in position. The back guide plate also acts as a finger guard and as a handle means for the sharpener.

Abstract: A hafnium nitride coating is applied over the cubic boron nitride layer of conventional CBN tools by the process of arc physical-vapor-deposition at temperatures below the tempering temperature of the core metal. The hafnium nitride coating protects the cubic boron nitride or diamond abrasive and the core, resulting in a grinding tool with greater strength and longer life.

Abstract: A hand held abrasive disk for deburring, honing, finishing and polishing, or sharpening a material that can be easily held in one's hand. The abrasive surface has a concave section for receiving the filings from the abraded material. A cap is releasably attached to the non-abrading surface to prevent irritation of the user's hand and to prevent damage to the surface upon which the stone is set.
