A long vertical cut to the top of the head with the arms fully extended, reaching over a low guard.

Extend the arms high and cut straight down at the crown. Because the cut is long and high it reaches over a low blade, which is why it is said to break . The expected reply is a high displacement with the crossguard, and the gloss continues from there.

The same principle appears as : whoever attacks low is reached from above.
