About this Mod
Copper has always been one of the least useful resources in Minecraft due to it only being used for a handful of uninteresting blocks. However, Cooler Copper brings the 1.21.9 copper variants of tools and armour back to 1.21.1 (Neoforge only) and 1.20.1.
The copper tools and armour will make a nice addition to modpacks as it creates an extremely easy decent early game tier of items due to copper being one of the most common ores and it's relatively good stats.
