So we are used to seeing a sword in the hands of a man. It is natural and to be expected. (The author wishes to point out here that even if it is natural, it's still hot.) However, in the hands of a woman a sword becomes a whole other beast. The woman herself often becomes a beast, though in a cunning and fiercesome manner rather than hulking and grisly.
Women, for the most part, are not wired to claim power with the same forthright audacity as a man. If a woman picks up a sword, you can be assured that she too seeks her own kind of power. Though the sword be heavy, and bear a hilt not meant for fair hands, she will raise it with finesse. And though she may assume a defensive stance at first, there will be a certain light to her eyes that says, "Yes, I am going to kill you. But won't you be surprised when you find out how."
