Knocking someone out with an edged weapon is no harder than with a blunt weapon; most people's conception of bladed weapon combat is completely wrong and based on the nonsense from films. Alot of real sword combat involves half-swording (gripping the sword half way along (only when wearing gauntlets obviously)) and once you half sword you can so easily smash someone in the teeth or around the head with the pommel or hilt once you are inside their guard.
Or you can change grip and use the hilt to trip someone by hooking the hilt behind their knee and pulling them over (polearms were actually often used for this as well). There was even a stroke where you hold the blade in both hands and smash someone on the head with the hilt (it was known as the Mortenslag or murder stroke).
Grappling is also absolutely essential to sword combat and once you have beaten someone (overcome their resolve to fight) you could break arms, bring someone to their knees etc with a set of arm locks. If you have someone in this position, you can do what you like with them.
