Sometimes you point a knife at someone, he panics and cowers in fear. He does not dare speak of the truth. Truth lies in the eyes of the beholder, but no, the blood that stains the knife does not reflect the truth in anyone's eyes. On blood smears hatred, and with hatred everything under the sun can crumble (even cookies!). But no, that's not the point. A knife can do wonders, it can also work the other way round. The sharpness, worked out by the blacksmith's own skilled deft fingers, will only be harnessed by the one who is deemed its user. When its time to kill, kill. A slash of a knife, will be so much more efficient that a ringing gunshot.
