"This is an elf-made blade," Hermione said to Flint in a voice that carried. "Did you know that house elves made weapons? Not for centuries, now. But they did. Don't like mess, elves. So this blade never spills a drop of blood. Just magically seals the cut behind it. There is no way to put it back on, once the cut has been made. A shame for you, but not for the women you were going to rape in your future." Hermione smiled down at Flint, then out at the room. The man closest took an involuntary step backwards at her expression.
