Abstract
Improved apparatus for sharpening a blade of an ice skate. The device includes a plurality of abrasive element holders, each having an external profile substantially the same as that of the other holders. Each holder is provided with a cavity formed therewithin within which an abrasive element can be received. An abrasive element is received within its corresponding holder with an arcuate surface of the element, having a radius of curvature different from that of an arcuate surface of another abrasive element, exposed on one side of the holder. Each holder can, in turn, be received within a chamber defined within a housing. The housing is provided with an elongated slot so that a blade of an ice skate can be passed therethrough and brought into engagement with the abrasive element received within the holder held within the housing. Means are provided to orient an abrasive element holder received within the chamber so that the exposed arcuate surface of the abrasive element can be engaged by the blade of the ice skate as the blade is passed through the slot.
