Duels are one hit things again and that is kinda sad really. Loved when it when skill of fighting instead of skill of bugusing appointed the winner 
Now, let's try this: Look for a skilled fighter IRL and ask him to swing a sword at you while you are wearing chainmail or leather armour. If you die from the first hit... well, that prooves that a skilled fighter can kill you in one hit.
Now, look for a newbie fighter, like, for example a guy that hasn't ever seen a sword, not even in pictures. My bet is that you'll survive a bunch of hits if you know how to dodge them (meaning armour training).
And now, a word of advice: Don't try any of the aforementioned things because there is a chance (a very high one) that you won't be able to take notes and sumarise this experiment because you'll be too dead to write. Instead, just think about it
I bet that the fighting system isn't yet, let's say, "tuned" and the devs will adjust it so it will seem more and more realistic.
And now, on topic: The silverweave attribute gives you a 5X slash multiplier for any item. But... and here comes the intheresting part, if the slash resulted is higher than 10, then the multiplier will be 1. Meaning the weapon will only bear a fancy name but no fancy heat treated-super shapened fancy cuting edge. That's why the LSs and claymores aren't that "sharp". And, if I was to put my 2 trias on it, they'll never get to 13 or 14 or 50 because there is a cap at 10.
