Mine's Tool Saver

Mine's Tool Saver helps protect valuable tools from accidental breakage. Use supported tools normally; at critical durability, the original tool moves to an empty inventory slot. Clear warnings let you know when tools are running low.

Features
• Automatically saves supported tools at 1 remaining durability.
• Warns when durability reaches 10 or fewer, with a cooldown to avoid spam.
• Preserves the original item's enchantments, custom name, damage, repair cost, and other data.
• Protects a critical tool when the inventory is full by blocking its use until space is available.
• Supports pickaxes, axes, shovels, hoes, and swords in either hand.
• Supports wood, stone, copper, iron, gold, diamond, and netherite tools.
• Handles inventory updates and notifications on the server.

How it works
Hold a supported tool and use it normally. A warning appears at low durability. At 1 remaining durability, the original tool is moved into an empty inventory slot. If no slot is available, actions with that critical tool are blocked until you make room. Repair the saved tool before using it again.

Compatibility
Game version: 26.3
Java: 25

Unbreaking continues to affect durability loss. Tools are not repaired, made unbreakable, or given new enchantments. Armor, bows, crossbows, tridents, and unusual custom tool behaviors are not included in the protected item list. In multiplayer, the server handles inventory changes and warnings.
