    You can find "definition of the skate blade" in ISU rules here

    Rule 500
    Definition of the skate blade and clothing
    1. Figure Skating blades used during competitions must be sharpened to 
    produce a flat to concave cross section without change to the width of the blade 
    as measured between the two edges. However, a slight tapering or narrowing of 
    the cross section of the blade is permitted
    My understanding is that it goes back to the "compulsory figure times". I was told that at one point some skaters "tried" to compete (only in compulsory figures) using different blade profile. It was similar to overturned trapezoid.

    The advantage of this blade profile was to avoid "flats" or "double tracings". The ISU reponse was the "Definition of the skate blade".
    I'm just curious if someone knows who were the skaters (or coaches) who "invented" this blade and when it happened.

    Finns used bones strapped to there feet with leather bands to skate 5, 000 years ago.

    Scandinavians first used metal blades 1800 years ago.

    The transition to metal blades was not fast as there are stories of skaters using bone blades in medieval London circa 800 years ago.

    This is a really interesting topic. Maybe it should be in GSD?

    I can add that when I heard about this story (many years ago) someone suggested that this skater was from Eastern Europe and it happened in the '60s or early '70s.
