Hmm:

A blade that can be used either separately or combined with its sheath (like Gambol Shroud), but when it is sheathed, it is used two-handed, in more of a bat'leth type of manner.

The sheath would be able to collapse, so when they are separate it could be used as a sort of small deflector or shield in its normal form (the same size as when it is used as a sheath), or it can collapse into a more sword or spear-like form.

And a gun somewhere, it obviously needs a gun.
