I think you're underestimating the strength/sharpness of Leonardo's Katana and if Sonic did brake the katana, Leo would still have the upper hand. He's not only a skilled swordsman, he was train every since he was small in the art of Ninjutsu and has mastered it over the years. He's also a strategist. Leo doesn't just rush into battles, like Sonic does, and start attacking. He plans ahead, always knowing his opponents next move.
