I don't have any but a fp-sword-script is not that hard to realise.
What you need is an animate arm+sword model and two vertex in that sword.
Now you put that model as world-model in front of the player (make it passable).
When the player hits the attack button you play the animation and trace from the sword-base to the sword tip to "cut" your opponent.
(Thats at least one methode)
