If you're looking for something like a cinqueda, Valandar's Build Your Own Sword Kit from Daz has such a blade, though it isn't a morph - the sword kit works as a series of props of different pommels, crossguards and blades attached to a handle figure. It looks good, though by default it loads with its centre of gravity far away from the handle figure, something which I dislike as I find it hard to predict what the rotation dials will do. You can adjust the COG, though.

I agree with everyone else that Omni's morphing sword looks great - pure fantasy, and it looks like a lot of fun to use. This and several other Omni products have been sitting on my wishlist for far too long.
