Bustermarm Sword is an Edolas Magic Item used by Pantherlily
Description
The Bustermarm Sword is an extremely large and characteristic weapon, being roughly three times its owner's size. The blade is straight and double-edged, with the cutting edges being far lighter than the dark, flat and massive part between them. It starts as “smaller” near the hilt, and then extends outwards in a pair of large protrusions, before barely reducing its width again in the rest of it. The most particular aspect of the Bustermarm Sword is its handguard: it takes the form of a large, monstrous feline head, with round eyes (portrayed as glowing, red Lacrima crystals in the anime), long ears acting as an added protection of sort, and a line of massive teeth on its lower end, in the direction of the hilt, which is covered in leather strips and quite thin in comparison to the weapon’s blade, but keeping up with it in length. The pommel at its end is supposed to complement the handguard, and thus takes roughly the form of a round, feline lower jaw, complete with massive teeth pointing upwards on its edges.
Abilities
Once it's abilities are activated, the lacrimas glow red and the blade lengthens until it becomes three times the size of Pantherlily. This sword is able to easily cut earth with little force put behind it and it is capable of cutting through iron. However, as Gajeel pointed out, the Iron Dragon's Scales that he manifests isn't "ordinary iron", and as such, proved resistant against the sword. It was destroyed by Gajeel.
