Skate blade (10), which has an outside edge and an inside edge (2, 3), in the middle region (1) of which the outside edge and the inside edge (2, 3) are parallel and have the same height, and the blade has an anterior region (4) in front of the middle region (1), where the height (z) of the edges (2, 3) increases in forward direction relative to the height (z=0) assumed at the middle region, and it has a posterior region (5) behind the middle region (1), where the height (z) of the edges (2, 3) increases in rearward direction relative to the height (z=0) assumed at the middle region, and the width coordinate (y) of at least one edge (2, 3), at least in the anterior or in the posterior region (4,5) increases along and arched curve with the distance from the middle region (1) relative to the vertical central plane (6) interpreted at the middle region (1), and at every location in front or behind the middle region (1), where the width of blade (10) exceeds the value assumed at the middle region (1), both edges (2, 3) have height coordinate (z) exceeding zero at identical length coordinates (x). |
