Has it ever occured to you, Master Ninefingers, that a sword is different from other weapons? Axes and maces and so forth are lethal enough, but they hang on the belt like dumb brutes. But a sword...a sword has a voice.
Sheathed it has little to say, to be sure, but you need only put your hand on the hilt and it begins to whisper in your enemy's ear. A gentle word. A word of caution. Do you hear it?
Now, compare it to the sword half drawn. It speaks louder, does it not? It hisses a dire threat. It makes a deadly promise. Do you hear it?
Now compare it to the sword full drawn. It shouts now, does it not? It screams defiance! It bellows a challenge! Do you hear it?
