The Armorslayer (斬鉄の剣 Zantetsu no Ken) is a weapon that can do great damage to classes such as the Knight and General. Its name has varied throughout the series. The weapon "Armor Killer" was in Ankoku Ryū to Hikari no Tsurugi and Mystery of the Emblem, then changed its name to "Armor Cutter" in Genealogy of the Holy War, and back to Armor Killer after that. Starting from Rekka no Ken, it was localized to "Armorslayer" in the English version of the games. It does not appear in Radiant Dawn. Its might is usually the same or around the Steel Sword; however, it is also heavier and has fewer uses (except in FE4 and FE5).
