*Throwing away the somewhat broken sword, and 13 others, I resheath two of the swords I had originally brought very carefully, making sure to treat my good swords with respect, as any swordsman should. Then, holding the sword I am about to undergo proper kenjutsu training with, I lift my head and look my sensei in the eyes as I prepare my response.*
"Kenjutsu is the art of wielding a sword for various techniques, which may or may not utilize chakra. Like taijutsu, most of the time kenjutsu will not require chakra, making it great for when a ninja is running low, or simply wants to reserve it. The Samurai from the Land of Iron are renown for their kenjutsu abilities and Iado, the art of unsheathing a sword, striking one's opponent, and resheathing. A skilled enough kenjutsu user can do this so fast handseals are useless, forcing one's opponent to rely on tai or kenjutsu."
