A disc blade sharpener. A wheel carriage includes a rotatable abrasive wheel contactable against the side surface of the cutting edge of the disc blade. A rotatable driver wheel mounted on the carriage rotates the disc blade while the abrasive wheel contacts and sharpens the cutting edge of the disc blade. The carnage includes an electric motor, abrasive wheel, and driver wheel that may be adjustably moved both in a horizontal direction and a vertical direction relative to the concave disc blade.
