The lateral parts of a ski or ice skate blade (4) has small extra blades (3) fixed to it. These grip the ice or snow when the angle of inclination of the blade or ski exceeds 45 deg. The blades are removable and their placing depends on the use of the skate or ski. The blades are fixed on by screws (2) and their length and angle of inclination is adaptable. They can be distributed along all the length of the blade or ski or along part of its length. USE - Additional edges for skis or ice skates.
