Both of those would be so impractical in a sword fight. #1 would bend and sway like a tuning fork and #2 would be so heavy it would be like swinging a ball and chain.
They are interesting to look at but wouldn't really server any use in a game or in the real world.
edit: this would be a much more practical sword. (sorry, it just bugs me to see weapons that would be useless in a fight)
