Abstract: An automated skate sharpening machine is provided. The machine includes a grinding wheel operable to rotate about a first axis by a grinding wheel motor; one or more skate holders to clamp a skate blade with its edge facing the grinding wheel; wherein at least one of the grinding wheel motor and the one or more skate holders are rotatable about a second axis perpendicular to the first axis.

Abstract: A device for trimming the high points off of the ice of a curling rink includes an elongated blade mounted to an elongated mounting block, and a plurality of setscrews threaded into threaded openings in the mounting block for adjusting the flatness of the blade, enabling a long blade to be used that is both accurate and relatively inexpensive.

Abstract: A guide assembly for an ice skate sharpener cooperates with a template of a desired contour of a skate blade to control the relative disposition of a sharpening wheel and a skate blade. The guide assembly comprises a base and a carriage slidably mounted on the base so as to be moveable, relative to said base, along a predefined path. A support is provided for connection to a skateholder. The support is connected to the carriage to permit movement of a skateholder in a direction normal to the path. The support inhibits relative movement between the carriage and a skateholder in a direction parallel to said path. A follower connected between the skateholder and template, control movement of the skateholder in a direction normal to the path as the carriage is moved along said predefined path. The skateholder therefore follow the contour of the template.
