he discusses flexible blades used in the dancing demos and fruit cuttings. reminds me of shinese dao, the fighting ones have stiff thick blades and the ones used in wushu 'dancing' have very flexible ones, especially near the tips, because they make a cool sound as they wobble & thus enhance the dance.
i have examples of both & yes, if sharpened the wushu one will cut, but i'd rather have the thicker dao if i were in serious need.
