Search the forums for the above question if you want a quick answer. I don't remember <img src="/ubbthreads/images/graemlins/wave.gif" alt="" />
Nobleman's sword isn't random, it's quest related and you can always find it there.
Now about the other weapon... some of the wise ladies of the forum <img src="/ubbthreads/images/graemlins/silly.gif" alt="" /> mentioned several powerful swords. I am still using the Singing Blade. It implicts Freeze[2] on hit.
