Medeco uses different keyhead designs for different keyways. For example I have a medeco padlock manufactured in 2009 with a round keyway. The core in this padlock is biaxial which traditionally uses square keys.

As for a side by side pin comparison of classic vs biaxial, here are pins taken out of a S&G 831-B (Medeco Classic) and my Medeco padlock (Medeco Biaxial) so you can clearly see the difference.
