Chain Blade

The Chain Blade is an Earth Land weapon.

Appearance
The Chain Blade is a sword of average length characterized by its mechanical nature and looks. It sports a notably long handle wrapped in bandages, allowing its owner to wield it with both hands (even maintaining a certain distance between the two of them), ending in a large pommel with an arched outer part. The sword's blade is double-edged, and is notable in the fact that it lacks a sharp tip, instead ending in a squared section. The handguard is the tool's most complex part, being massive and hollow on the edges, extending for several inches over one side of the blade itself, sporting two small wings on each of its sides, meant to offer protection to the hand, and bearing two openings on one of such sides, each surrounded by bolts: the first is small and trapezoidal in shape, serving no visible practical purpose, while the other has an elongated, complex polygonal shape, and a prominent lever jutting out from it, which is used to activate the weapon's special qualities.

Description
A weapon empowered by mechanics rather than Magic, the Chain Blade is more than a simple sword: by manipulating the lever located on one of its sides, the user can almost instantly reveal several smaller segments of the handguard's protrusion (usually partially overlapping), which together extend some meters past the squared blade and end in a secondary, smaller one-edged blade, usually kept hidden, which sports a sharp point, and is thus suited for stabbing. This allows the sword to double as a polearm of sort (with the added blade granting it the possibility of both slashing and stabbing, much like a halberd or a naginata); not only that, the speed at which the weapon elongates is fast enough to catch opponents off-guard, making for an effective and possibly lethal surprise attack, and the sheer force present in such motion is such that even objects out of its physical reach can suffer heavy damage, being struck by an aerial shockwave which can cause devastating effects, obliterating large-sized trees with ease.
