08/17/2019
"Mark, that is how you shall drive the two Upper-slices
from the two Lower-slices. Undertake it thus: When he runs in
to you on your left side with up-stretched arms, then invert
your sword and fall with the long edge in the arm, under his
pommel, and press fast upwards and step therewith on his
right side, and Wind your pommel below through, and come
not from his arms with the sword, and turn the sword from
the Lower-slice into the Upper-slice with the long edge over
his arms."
This technique is also described in the video here.
