The appuntata in classical Itlaian fencing with the dueling sword

This is a stop thrust into the riposte of your opponent. A thrust in tempo. Those actions could be very useful but also very dangerous for the one who tries it. that makes it an advanced technique for fencer. Because if the blade is sharp and pointy you do not want a double hit, you do not want to get hit. This makes it a deadly martial art as it was before the sportification.
