Jason Kingsley has another good video on the weapons that medieval knights actually used on the battlefield.

He also covers the pollaxe (note the spelling, from “poll” meaning the top of the head), which was for fighting other knights while dismounted.
Swords get only a brief mention — for all their symbolic value, they’re just not much use against serious plate armour.
