Sword
From Destinypedia, the Destiny wiki
Swords are a class of heavy weapon introduced in The Taken King expansion. Unlike all other player weapon types, Swords are melee weapons and have an alternate "Guard" function that can partially deflect damage from incoming enemy attacks. Prior to the addition of Swords, the only melee weapons players could use (excluding the Hunter's knife) were Knight Cleavers and The Aegis relic, which were available temporarily in specific situations.
