Why does this make it look like the cut has been disrupted? I would think the tip of the sword would simply stop, very smoothly, as though it had met a gelatinous material.
Is there maybe, supposed to be a sort of projection of ki outward along the length of the blade?
Don't know about cutting - this is striking, with the body and a blunt weapon. Or, another way, a striking exercise to develop body skills, using a blunt weapon.
