Skate blade and apparatus for removing material from a skate blade

A blade for a skate for skating on ice, comprising:

• ice-contacting material with an ice-contacting surface for contacting the ice, the ice-contacting surface defining a longitudinal profile along a length of the blade and a transverse profile along a cross-section of the blade taken at a lengthwise midpoint of the blade;
• wherein the longitudinal profile has a radius of curvature that varies smoothly over a majority of the length of the blade;
• wherein the transverse profile has a radius of curvature that varies by no more than 10% over the entire cross-section of the blade.

A blade for a skate for skating on ice, the skate comprising a skate boot configured to receive a foot of a user, the skate further comprising a blade holder disposed below the skate boot and configured to hold the blade, the blade being elongate and having a length that is divisible into five fifths of equal size, the blade comprising:

• ice-contacting material with an ice-contacting surface for contacting the ice, the ice-contacting surface being longitudinally profiled to have a first radius of curvature at a first point in the second fifth of the blade and a second radius of curvature at a second point in the fourth fifth of the blade, with the second radius of curvature being greater than the first radius of curvature by at least 10%, and with the blade being transition-zone-free between the first point and the second point.
