In this video I show the way now I execute my thrust from Halpshilt. This action is based on the Folio 11v of the I.33 manual which show a similar action against prima custodia, action which is by the way described as a “plaga” a cut/blow.
In fact the action shown in the I.33 is a blow, but sometimes happens that in traditional training methods we find an action really dangerous to practice replaced by a more controllable one, like probably in this case. There is also a lot of chance that the action was simply a blow, both in training and in the “Hypothetical reality” but, looking at the description, a thrust can make sense. Also, from a purely strategic point of view a thrust is far better.
