The Warlord of Oz's sword is a different weapon again.

The Warlord of Oz's sword is a different weapon again. Within Grimm Fairy Tales #116–117, it is used against Arcane Acre's protective enchantment. The Warlord cuts through the school's barrier with his own blade. The explanation given afterward is that the weapon can cut magical enchantments. Meanwhile, Bloody Bones is trying to obtain Calesvol from inside the school. Those are separate parts of the attack. The weapon that gets the attackers through the protection is not the sword they're trying to steal. By the end of that confrontation, Bloody Bones has escaped with Calesvol. That changes its custody, but it doesn't turn it into the Warlord's enchantment-cutting blade. I'm keeping the latter under that descriptive name here because I haven't verified a proper name for it in those issues. Its appearance in the main series is enough to discuss that particular use without pulling in the rest of the Warlord's Oz history.
