SwordRename

What it does

• Renaming a netherite sword to dragonslayer (case-insensitive) automatically tags it with custom model data and swaps in a dragon-slaying blade model and texture.
• Renaming it to anything else clears the special model so the sword looks normal again.
• The mod runs server-side and ships a built-in resource override for the netherite sword model plus a new dragonslayer texture.

How to use

• Rename any netherite sword to dragonslayer in an anvil or via commands; carry or equip it to see the new look.
• Rename the sword away from dragonslayer whenever you want to revert.

Notes and limitations

• Only netherite swords are affected.
• The override relies on custom_model_data: 1; other packs that replace the netherite sword model may conflict with this look.
• Swords update when a player has them in their inventory; items left in containers get updated once a player picks them up.
