It is obvious that the sword is a thing with which one strikes and the spear is a thing with which one thrusts. . . . The cut has its rules, and thrust has its rules, and if a person does not know their function, then he will not do full justice to them. Even though the heart may be strong, if the form is not appropriate, then the stroke will fall where it should not fall. If one deviates from the principle of technique, one will not attain what one desires.
—from Tengu Geijutsu Ron
We should stop doing tachi-dori and jō-dori in public demos. There are lots of real swordsmen in the audience, people who’ve really trained with weapons, and they know that we can’t really take swords and staffs out of people’s hands when they are attacking us. We are making fools of ourselves.
