An obsession with or addiction to cosmetic surgery (medically necessary surgery, reconstructive surgery and single uses of cosmetic surgery don't usually qualify). "The knife" in this case refers to the scalpels associated with this sort of surgery.
It's sad that so many celebrities today have an addiction to the knife.
