painandgreed said:Back to mercurial swords. How about this: A single edged, broad bladed sword (soemthing like the Chinese Dadao?) with the channel being a tube down the spine and not actually in the blade, perhaps a flattened pipe. The mercury normally resides in the pommel for a reasonably balanced weapon. When needed, it can be upturned, the mercury flows to the end of the blade and it can be used more like an axe. That sound reasonable for a fantasy weapon developed for execution and fighting zombies (where physical damage, not blood lose due to penetration of organs is important)?
That might actually work in one sense, that you could have the mercury in there. As I mentioend there is a type of Dao (chinese saber) which had a bead rolling back and forth in a groove just under the spine almost exactly as you picture above. They called this 'rolling pearl', it may have existed in India and Persia as well. Theoretically it was for aesthetic purposes or perhaps to help timing or something, because it certainly wasn't heavy enough to effect the balance in any way. I think that would actually be the root of the problem. Unless you had some magically heavy substance, or maybe plutonium (perhaps somebody can do the math) I don't see how it could be heavy enough given the tiny space you could get away with, to effect the balance.
Here is a photo of one of these beautiful swords, incidentally, an antique from the Ming dynasty....
