skate sharpening

Skate sharpening is the process of restoring the edges of ice skate blades to optimal sharpness and profile.

A sharpening machine grinds a concave groove (the hollow) into the blade's bottom, creating two distinct edges that grip the ice.

Skaters choose different hollow depths depending on their sport and preferences—hockey players often prefer shallower hollows for speed, while figure skaters may want deeper ones for precise footwork.

Regular sharpening is essential because dull blades reduce control and stopping ability.
