Backbiter
What is Backbiter?
History of Backbiter
Backbiter is a double-edged sword made of two metals: tempered steel and Celestial Bronze. This means that it can wound or kill mortals, demigods, and immortals alike and sever their souls, which makes it similar to Stygian Iron. Apparently, Backbiter is also capable of "slashing" open portals, or travelable rips through space and time, as seen in the final scene in which Luke and Percy meet in The Lightning Thief. It is a long sword for one hand, as it is described as being a foot longer than Percy's Riptide, or four feet long.
