  • Patent number: 5462476
    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.

  • Patent number: 5458534
    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.

  • Patent number: 5449317
    Abstract: A drilling, grinding, and shaping guidance assembly particularly suited for attachment to a precision jewelers' grinding and cutting handpiece. The guidance assembly is integrally attached or clamped on the jewelers' handpiece. The guide arms of the assembly have desirably shaped terminal portions adapted for engaging a workpiece which permits specific cutting or grinding tasks to be performed more accurately than can be performed without the guide arms.

  • Patent number: 5445050
    Abstract: A hand-held ice skate blade sharpener tool is provided which includes a configuration for honing, concurrently, the hollow groove and the side walls of an ice skate blade, to dress the edges of the blade in situ, at any convenient time. The tool has a guide to accept the blade's hollow surface and its edges, and to align same with the honing surfaces of the tool. An extruded housing of plastic or like material surrounds the honing surfaces and is of a shape to provide a grasping surface while protecting the hand from the sharp edges of the skate blade. The entire assembly is relatively light weight and relatively small, thereby rendering the device reasonably inexpensive to manufacture. The tool is intended to be disposable.

  • Patent number: 5431597
    Abstract: A hand held skate blade sharpening tool has a rotatable sharpening stone retained within a channel-shaped body member. Removable pins mounted on the body are located adjacent the outer ends of the stone to limit longitudinal movement of the stone within a channel of the body member. The body member has an access slot extending radially from the stone. Elongated guides projecting upwardly adjacent the slot are transversely spaced at a distance substantially the same as the width of the skate blade to guide and limit lateral movement of the blade within the slot. A transverse groove interrupting the slot and guides is open to the channel exposing the stone. This enables the stone to be manually rotated within the channel to rotate an unused sharpening surface into alignment with the slot.

  • Patent number: 5426895
    Abstract: A windshield wiper blade cleaning device is disclosed having a channel for receiving the tip of a wiper blade, the channel having a frictional base for removing dirt from the tip of the blade as the blade is drawn longitudinally through the channel. In an alternate embodiment, the channel also has frictional walls for cleaning the sides of the blade. In described embodiment, the base and/or walls are made frictional by means of projections, filaments, or abrasive materials.

  • Patent number: 5404679
    Abstract: A portable manual sharpener for cutting tools such as knives, scissors and the like includes a base having a first stage sharpening station which includes a stationary non-rotatable support member with an abrasive coated planar surface on opposite sides of the support member. A pair of symmetrical slots are disposed adjacent to the planar faces with a guide surface located in each slot at a predetermined angle to the planar surface. A hold down device maintains the cutting blade in contact with the guide surface as the blade is moved through the sharpening station with the cutting edge facet of the blade in sliding contact with the abrasive particles on the planar face. The base includes an area which can be conveniently hand held.

  • Patent number: 5383307
    Abstract: A hand held skate blade sharpening tool has a rotatable cylindrical member having an outer sleeve made of a sharpening stone material retained within a channel-shaped body member. Removable screws threaded through the body engage bearings rotatably mounted on the outer ends of the cylindrical member to limit longitudinal movement of the stone within a channel of the body member. The body member has an access slot extending radially from the stone. Elongated guides projecting upwardly adjacent the slot are transversely spaced at a distance substantially the same as the width of the skate blade to guide and limit lateral movement of the blade within the slot. Grooves in the bearings are aligned with the slot whereby the bearings do not interfere with movement of the tool along the skate blade. A transverse groove interrupting the slot and guides is open to the channel exposing the stone sleeve.
