I have noticed that holding a sword with both hands may provide more battering strength to overwhelm your opponent or enemy, but unless you are of the upmost physical build, your arms quickly tire, leading to clumsy strikes and increasing dependency on restoring your stamina in the middle of a duel. Holding a sword in one hand however, has the benefits of offering you flexibility in how you swing, fencing, and very minimal taxation on your arm's strength when fighting. However, depending on how strong your opponent is physically, defending with a one-handed sword can lead your arm to being strained very quickly, and being easily disarmed, and I have found the best way to counteract this is to try to avoid your opponent's swings altogether with feints and dodging, rather than meeting your opponent's blade head on with your own.
I want to know your opinions on this. What do you think is overall better?
