Answer 1

This is a modern translation of your quote:

He's tougher than the Prince of Cats (a figure from Medieval lore) . He does everything by the book. He fights like you sing at a recital, paying attention to time, distance, and proportion. He takes the proper breaks: one, two, and the third in your heart. He's the butcher who can hit any silk button. A master of duels. He's a gentleman from the finest school of fencing. He knows how to turn any argument into a swordfight.
