That explains my difficulty, then: For some reason, I had it in my head that it was basically a straight-edged sabre (if that makes any sense). That (and being forced to wield it right-handed) led to some pretty piss-poor performance.

If I ever do get into a dream duel, you are like so totally my second. In fact, I'd make you my first if such a thing were permitted. (Sadly, I strongly suspect there's no designated hitter rule in the bylaws of duello.)
