In the spontaineous phase, we do not even graft per se, rather we fill the dead space. It is what I do with Snapping Twig, as the head goes back following the hammerfist, the orbit of my fist may strike the solar plexus or abdomen, bringing them back for the elbow. Inevitably from the handsword or heel palm as some learn it, the head goes back, if you twist or pull they stay there.
