Your weaknesses as a swordsman are long-ranged attacks (your reach isn't that far), blocking heavy objects (the sword will break), cutting through rock, metal etc (sword isn't strong enough). For the last two a special sword can be made.
Your strenghts are close-combat, you have an advantage over Taijutsu, since this is used with your hands most of the time, and you can cut those, blocking other weapons (some swords can be moved very fast)
