From Destinypedia, the Destiny wiki
Raze-Lighter is an Exotic Sword introduced in The Taken King. It is the upgraded version of Sol Edge, obtained through A Sword Reforged. The blade came into the possession of Lord Shaxx at some point after the Taken War.
Raze-Lighter's special attack is Phoenix Uppercut, a powerful single-target swipe that will knock the enemy into the air. The uppercut will kill or nearly kill just about any major enemy, especially if they're solar-shielded. It also comes equipped with Solar Guard, which protects against Arc and Void attacks, and increased armor.
