For a sword, to be wielded like a sword, and damage like a sword, has to be built like a sword. A sword made of ice would function in a different way than a sword made of metal. i.e. something small enough to not fall apart when wielded.

Besides, the philosophies behind water bending (push-pull, flowing etc) do not back up an ability to create a balanced, solid slashing weapon. They even less support the creation of something like a hammer. it's just not water bending style.
