“Flower of Battle,” a combat manual created in the first decade of the 1400s

No one sane would take off their helmet in the middle of a battlefield for the most important fight/battle. You don't slice with a sword through plate armor or decent chain mail. It just doesn't happen in real battle conditions. For that matter, it's not so easy to slice through padded cloth gambeson armor! Also, the "reality-tv" shows that have covered historical weapons are often bogus. You "half-sword" to wrestle your opponent to the ground, then guide the stabby point of a specialized sword through an eye-hole or other gap in their armor. Likewise, real battles between knights didn't consist of them bashing at each other, using their swords crudely like glorified metal clubs.
Long exchanges of blows/parries in movies are just for show. In fact, there are fighting manuals that urge you not to parry if you can help it, but rather always "bind" a weapon in the process of some kind of counterattack.
Social class meant a hell of a lot. On the battlefield, it determined how much armor you could afford to keep up, which made a big difference to how likely you'd be killed.
Most swords were sidearms, not main battlefield weapons, analogous in role to an automatic pistol vs. an assault rifle. For most of western history, and in many other parts of the world, the main battlefield weapons were polearms, often used in conjunction with a shield. This even applies to a certain extent to Japan! (Though the naginata fell out of favor and for awhile actually became a sign of social status for women.)
Katana are not magic, and there were and are european, middle-eastern, and indian subcontinental swords capable of equivalent feats of cutting.

I was disappointed that they weren't a free podcast, but ... I guess that's a reasonable price if the material is well done.

"Many of General Mackay's officers and soldiers were cut down through the skull and neck to the very breasts; others had skulls cut off above their ears like night caps; some soldiers had both their bodies and cross-belts cut through at one blow; pikes and small swords were cut like willows..."

Skallagrim did a recent video which shows that a held (not anchored) spear shaft is pretty hard to cut in one blow. However, it's quite possible to destroy a spear if 3 or more cuts are placed in close proximity, even when the spear is held in the hands. I would guess that's what the author is talking about.
"I say that when I taught this art I taught it secretly, so that no other person was present except for the student and some close relatives.
Also, it happened that when others were present they stayed with Sacramental promise not to divulge the plays they saw from me, Fiore.
And most of all I was wary of fencing Masters and of their students. And they invited me, the Masters, out of envy, to fight with sharp and pointed swords in an arming jacket, without any other armour except for a pair of chamois leather gloves, and all this had happened because I did not want to practice with them nor teach them anything of my art.
And this accident happened five times, so that I have been requested ['called out']. And five times, for my honour, I have had to fight in strange places, without relatives and without friends, not trusting others, but in God an the art and in myself, Fiore, and in my sword. And by the grace of God I, Fiore, remained with honour and without scars upon my person."
