Are Valyrian steel weapons an advantage against an armored opponent?

[The Sleeper]

This is a question for the history buffs out there. of which I am not. As far as I can tell the way to get through armor is to have a weapon that can deliver momentum on the smallest surface possible. Thus you'd go for hammers or maces first, then axes with swords being the least effective. Wouldn't the fact that Valyrian steel swords are lighter make them actually less effective than regular ones despite the increased sharpness?

I am not an expert either, but against an armored opponent, it might. Of course the added dexterity of using a lighter blade might offset this. Or you could go for the "it's magic" solution, in which case it's superior, case closed.

I've always thought the point is that it's lighter but also more effective, kind of like Elven swords in LOTR

Most people don't have plate armor though. If they do then as you said swords are terrible in general so you wouldn't be trying to slash through it, you'd be trying to hit the weak spots at joints. The advantage is that it's lighter, so you get tired less quickly.

Depending how stiff it is you can also use a sword for stabbing, which would make the durability of VS far superior to a normal sword vs plate since a normal sword would lose its point very quickly doing that.

[The guy from the Vale]

No. A lighter sword is easier to handle and thus better to exploit weak spots in the armor. The increase in weight of a regular sword doesn't help all that much with armor penetration.

So it would still be better because of its other advantages since one wouldn't try to slash through armor anyway. Ok, that's good enough for me. Cheers.
