  • Patent number: 6030283
    Abstract: A hand held ice skate blade sharpening tool has a holder having a rotatably mounted cylindrical sharpening stone material. The holder and stone are retained with a two-piece body. A releasable connector holds the body together. The body has a longitudinal access slot extending radially from the outer surface of the stone. Elongated guides projecting upwardly adjacent the slot are transversely spaced at a distance substantially the same as the width of an ice skate blade to guide and limit lateral movement of the blade within the slot during the sharpening procedure. Shims are positioned in grooves in the guides to adjust the width of the slot to accommodate ice skate blades having different thicknesses. A transverse groove intersects the slot and guides. The bottom of the transverse groove is open to the channel exposing the outer surface of the stone.

  • 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: 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.
