Swinging, moving, striking, or otherwise inducing movements or forces that will cause blood and tissue to be dislodged from a blade. This is often distinct from wiping the blade to remove residue, which would normally be an additional step prior to performing Noto. Wiping the blade is not often depicted in Kata, but would be a required step to ensure any residual blood does not foul the Saya and subsequently begin to rust the blade.
