A possible action introduced in play 24. It is performed from binding below and on the left. You perform a moulinet-like action that brings your sword from below position and cuts the opponent's hands from above. This is similar to durchtreten, but it is performed low and always under the shield arm. Thus it is not suitable as a way to yield under the opponent's pressure, but it can be done from a quite low position.
I.33 doesn't have any name for this action. The priest would probably describe it as pull back into prima custodia, and then cut in a similar way to halpschilt, but under the shield arm. That's why play 24 talks about scholar pulling back into prima custodia.
