Switch Axe

The slasher axe is an upcoming weapon in Monster Hunter tri. An attack demo video was shown, and the moveset is a complicated but impressive repertoire of far-reaching swipes of the axe and quick swipes of the blade. However, much of the attacks leave the hunter wide open, compared to the Great Sword and especially  the Longsword. Furthermore, it can't block.

This makes the axe out to look like some kind of super weapon, which may mean its materials are hard to get, or it can only be obtained at a high level.
