Skate sharpening

Control and stability: Sharp and properly sharpened skates provide greater control and stability, allowing the skater to maneuver more easily and react more quickly to changes in ice conditions.
Smooth gliding: Sharpening ensures smooth gliding on the ice, reducing friction and allowing the skater to save more energy for turns and jumps.
Ice conditions: Different ice conditions (eg. soft or hard ice) may require different sharpening angles.
