There is another (way)
I just posted this on a different thread, but it seems better here:
If you sidestep away from the sabre just before it gets back to you after a throw and hold down the primary attack button, it spins around you. If you move into it, it returns to you - but if you stand still, it just keeps going. It's hard to time though - but I've seen people do it very well. Oh - and I haven't tried this under 1.03, so not sure if it still works the same.
I've even once seen a guy on the Raven duel map get it to do this near a corner of a wall, then run away and come up behind someone who was standing there watching it - and the sabre was still going - it didn't come back to him until he went up to near it again. It was quite bizarre - but I'd love to know how to do that.
