yes, the reality of armored combat during medieval times is very different from how it is portrayed in modern media. the sword's blade was actually mainly used against light unarmored opponents, but when two armored opponents fought they would actually hold their swords by the blade, and bludgeon each other with the pummel and hilt of their swords.
armored combat is also the main use for blunt weapons like clubs, maces, and warhammers.
besides all that, armored knights would also just tackle each other to the ground and then pull out small knives to stab away at the small gaps in their opponent's armor.
the reality is, most, if not all armored knights died from being crushed inside their suits.
