I got to be honest with you, I always looked at sword arts as a way of fighting of true warriors; standing eye to eye with your opponent and fighting with only aid of a single tool. But other then that, kenjutsu or sword arts, as you said it yourself are technique that are based upon sword usage. Kenjutsu is, one could say an addition on taijutsu. Both are connected with body arts however with taijutsu it is without any tools as to add onto the attacks, whereas with kenjutsu we have utilisation of a sword as to make our attacks more powerful as well as deadly. Swords on their own are already deadly because of their shaprness, however with addition of chakra onto them we are taking them on the next level with kenjutsu. Although, keep in mind that not every jutsu on the list actually needs infusion of chakra into the sword as to make an attack but falls under kenjutsu.
So the next thing that we are going to cover is actually difference between a one-handed and two-handed attack. So what can you tell me about the two?
