ABSTRACT:
A skate blade has a front curved section having a front balance point, a rear curved section having a rear balance point, and a middle section having a center balance point. Each balance point is a point on the skate blade over which a skater's center of gravity lies depending on the skater's position. The skate blade is shaped such that the middle section is substantially flat. Additionally, the blade is shaped such that more of the blade extends away from a blade holder at the rear balance point than at the front balance point.
