Ice skate blades represent the sole interface between a skater and the ice, a thin line of contact that must generate sufficient friction to melt the ice to allow gliding but not add drag under one state of usage and in another generate sufficient traction to support sharp turns and stopping. Today's skate blades have a single hollow of predetermined profile across their width terminating in sharp edges at the outer limits of the skate blade. However, improved performance at both the competitive and recreational levels of skating and hockey in terms of the athletes and their sporting equipment has not followed through into the ice skate blade despite significant innovations in the skate boots. Accordingly it would be beneficial to provide increased design flexibility by allowing multiple hollows per blade such that the performance can be adjusted between inner and outer edges as well as across the entire width. |
