Breaker Weapons, as referred to in Fire Emblem: The Binding Blade, are weapons that break the normal Weapon triangle. The Axe group is the only group with two Breaker Weapons (Swordslayer and Swordreaver). It should be noted that although they beat the type of weapon the usually lose to, they lose to the type of weapon they usually beat (Ex. Swordslayer beats Swords but loses to Lances)
