“The knife he held was obsidian, sharp enough to cut a dream.”

“Discipline and constant work are the whetstones upon which the dull knife of talent is honed until it becomes sharp enough, hopefully, to cut through even the toughest meat and gristle.”

“A mind is only as sharp as the knife, that strives to cut through thoughtstoo tough for the blade, before it breaks or goes dull.”

“The thought makes me reach back for my knife, my sharp, throat-cutting security blanket, as I look around.”

“So you want a knife, a nice sharp knife. You hone that blade to its limits. It even cuts through stone when you want it to. It saves your life. And then you're outraged when it cuts you accidentally. You see, knives don't switch off. And neither do people, not when you hone them to a fine edge.”
