Breaker Blade

The Breaker Blade is one of the weapons that can be dropped by defeating the Wall of Flesh. While slightly weaker than Night's Edge, it is a much bigger sword and has stronger knockback. Due to its size, it also may hit a foe multiple times with only one swing, making it a very efficient weapon.

Trivia

 * This item may be a reference to the Buster Sword wielded by Cloud in Final Fantasy VII. It bears a striking resemblance to the blade and even appears to have a pair of "materia" attached, as can be done in that game. The name is also similar to that of the Buster Sword and brings to mind the "Limit Breaker" skill. Due to the segmented parts on the blade however (base, mid, top) it closer resembles the buster sword used by Cloud Strife in the Final Fantasy movie - Advent Children.
 * Due largely to the teeth on its blade, it also resembles the chainswords of the Warhammer 40,000 universe; however that could simply be due to its pixelated graphics.
 * It has the longest range and strongest knockback of all of the swords in the game.
