It is the only sword that can damage Ganon without requiring the use of the Spin Attack in the original SNES version of the game, although in the GBA version, the Tempered Sword can do so as well, though it deals less damage. Despite being derived from the Master Sword, its artwork has a radically different design to it, namely the ricasso being less apparent in the blade, the Triforce mark being closer to the hilt, and the hilt, aside from being colored green instead of blue, is sleeker and straight-edged rather than thick and curved, as well as lacking the central jewel.
The following section is not part of the Zelda canon and should not be taken as such.
In Ancient Stone Tablets, the Sword is known as the LV4 Sword. When the Hero of Light draws the Master Sword from the Lost Woods, they obtain it at this power level from the start, due to it being strengthened to this state by Link prior to the events of the game. When obtained, the rental Shops will no longer offer a higher level.
These names, though from official English sources, are not considered Canon by Zelda Wiki as they contradict a name or names from a higher-priority source.
