ABSTRACT:
Blade sharpener apparatus and method for ice resurfacing machines which can include a tabletop for laying a longitudinal blade from an ice resurfacing machine thereon in a stationary position. A moveable carrier assembly attached to the table includes a drill press power head that can be lowered from a raised position so that a rotatable stone sharpening wheel is laid against the edge of the blade needing to be resharpened. A stabilizing guide can slide against a lower surface of the table under the blade while the sharpening stone wheel rolls across the longitudinal blade. The sharpening stone carrier wheel can sharpen the blade within minutes in a single pass. Liquid can continuously cool the blade sharpening, and can be recycled for reuse. The invention can sharpen other blades such as but not limited to paper cutting blades, and the like.
