Middle Iron Gate  

This is the Middle Iron Gate/Half Iron door of Fiore de Liberi:
This is Half Iron Door, because it stays in the middle
and is a strong guard. But, she wants a long sword. She throws
strong thrusts and beats with force the swords upwards, and
returns with a downward blow for the head or arms, and
returns to its guard. But it is called Door, because it is strong
and it is a strong guard that badly it can break without danger,
and without coming to the close.
