A portable skate sharpener has an elongated hollow main body having an electric motor adjacent one end, the electric motor having an output shaft extending in a longitudinal direction in the main body, and a grinding wheel mounted on the shaft for rotation in a plane perpendicular to the longitudinal axis of the main body. The main body has an aperture below the grinding wheel for receiving an upper edge of an upturned skate blade to enable a skate to be sharpened when held in an inverted position by holding the main body with one hand adjacent the motor end and another hand adjacent an opposite end of the main body and, while the motor is operating to rotate the grinding wheel, manually moving the sharpener in a direction transverse to its length with the skate edge in the body aperture and in engagement with the grinding wheel.

A portable skate sharpener comprising an elongated hollow main body, an electric motor, said electric motor having a manually grippable housing secured to one end of the main body and an output shaft projecting from the housing and extending in a longitudinal direction in the main body, and a grinding wheel mounted on said shaft for rotation in a plane perpendicular to the longitudinal axis to the main body, said main body extending beyond the grinding wheel in a direction away from the electric motor to provide a manually grippable main body portion on the opposite side of the grinding wheel to the manually grippable motor housing, said main body having an aperture extending in a direction perpendicular to said longitudinal direction below the grinding wheel for receiving an upper edge of an upturned skate blade to enable a skate to be sharpened when held in an inverted position by holding the motor housing with one hand and holding the main body portion with another hand and, while the motor is operating to rotate the grinding wheel, manually moving the sharpener in a direction transverse to its length with the skate blade edge in the aperture in the main body and in engagement with the grinding wheel, the main body carrying means for dressing the grinding wheel at a position above the grinding wheel, said dressing means comprising a plunger projecting into the main body above the grinding wheel and carrying a dresser member at its lower end, said plunger normally being resiliently urged upwardly to an inoperative position and having an upwardly projecting end manually engageable to move the plunger downwardly to cause the dresser member to engage and dress the grinding wheel while the grinding wheel is being rotated by the electric wheel.
