Terry Pratchett. Guards! Guards! (№ 439729)

He never liked swords, you feel somehow insecure with them, but a carcass knife is another matter. It has weight. He has a purpose. The sword is fanned with a halo of nobility (unless, of course, it belongs to the same Nobbs - then there is more rust in it than anything else), but the carcass knife has great practical value - it cuts very quickly into small pieces.
