"The knives in my apartment are only sharp enough to open envelopes with. Cutting a slice of coarse bread is on the borderline of their ability. I don't need anything sharper. Otherwise, on bad days, it might easily occur to me that I could always go stand in the bathroom in front of the mirror and slit my throat. On such occasions it's nice to have the added security of needing to go downstairs and borrow a decent knife from a neighbor."
