An elongated skate blade for an ice skate, the blade including first and second acute-angled cutting edges formed longitudinally on opposed sides of the blade for cutting engagement with an ice surface, and a generally downwardly facing longitudinally extending bottom surface extending transversely from the first cutting edge to the second cutting edge. The bottom surface includes first and second longitudinally extending edge faces rising upwardly and inwardly from the first and second cutting edges respectively, and a longitudinally extending middle face centrally disposed between the first and second edge faces. The middle face has a substantially flat or downwardly convex profile in transverse cross-section for at least one-third of the distance from the transverse center of the blade to each side of the blade. Where the middle face is downwardly convex, the radius of curvature exceeds the width of the blade for at least one-third of the distance from the transverse center of the blade to each side of the blade.
