They aren't, but there is some pretty awesome fluff about other kinds of knives in the setting. Just thought I would share some lore on that subject.
Lelith Hesperax, the leader of the dark eldar succubi, fights with a pair of very sharp knives. Her skill with them is so great that she can still kill assault terminators whenever she feels like it.
Konrad Curze, the Primarch of the Night Lords traitor legion, used knives as very effective projectile weapons.
Grendel's Claw is a knife from a Dark Heresy campaign that was used to kill multiple daemons of Khorne, including a Bloodthirster. No power field involved, just faith in the emperor and some ridiculous luck with the dice. It's user, Grendel, has been referenced in a Dark Heresy supplement.
