Durability Guard
by lyvt
Durability Guard stops a tool from being used to break a block once its durability falls to a set threshold, so a pickaxe is not lost to a final hit.
What it does
The mod watches tool durability and, when a tool reaches the configured threshold, blocks left-clicks with that tool. A player who wants to keep the tool can stop using it at once, while the lock applies automatically at the moment durability drops to the critical level. The threshold is adjustable across a wide numeric span, so it can match how a player works.
Feedback comes in three forms: an audible sound when a tool is locked, an action bar message that briefly reports the protected tool, and an in-game settings screen opened with the O key, where every option can be changed without leaving the world. The mod is published for Fabric only, for 12 release versions across 1.21 – 1.21.11. It is client-side only, so servers and other players do not need it. The code is released under the Apache License 2.0, and the mod is not open source.
Files exist for 1.21 – 1.21.11 with 1.1.2 as the latest build for 1.21.11, published on 2026-04-08. The mod was first published on 2026-03-14.
Key features
Automatic tool locking
Left-clicks are blocked once a tool's durability reaches the configured threshold, protecting it from being broken.
Configurable threshold
The durability level that triggers the lock is a user-chosen value.
Sound warning
An audible cue plays when a tool gets locked, and the sound can be switched off.
Action bar notice
A brief in-game message appears when a tool is protected, without interrupting play.
Compatibility
Latest build for each game version and loader.
1.21.x12 of 12 versions with builds
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Netherite tools
A netherite pickaxe that is nearly worn out cannot be used to break a block by accident, so the last durability points stay on the tool.
Who it’s for: Players who run long survival worlds and want to keep valuable tools from being lost to a single final use.
How it compares
NoTollBreak is Fabric-only, client-side only and published for 1.21.11 under All rights reserved, so it is not open source. Tools Durability HUD is also client-side only and Fabric-only, but its files target 1.21.4 and it is released under the MIT License without open source status. Low Durability Warning is client-side only, targets 1.21.11 and is open source under the MIT License.
