In reply to Basemetal:
I don't remember those at all, though 1980 is a little before my time. I do remember Chouinard Rigids which had a flat frame and fairly short points, made or marketed by Salewa in Europe.
I had a pair of normal Salewa Hard Ice Classics, the points of which I sawed down short for mixed, to great effect.
