Everything is Copper Mod (1.21.1, 1.20.1) adds a lot of things made of copper. The developer added copper ore to the game from Minecraft version 1.17, but it has not been used much. Copper in the current game is still lagging compared to other ores and is not as popular. The Copper Mod adds a lot of things made of copper, such as tools, weapons, armor, and more. This mod adds new items such as copper armor, swords, and axes that you can use instead of iron or stone in some cases. Copper tools are much better than stone tools and can be used to mine some materials faster, but they are not as strong as iron tools. Copper blocks can be used as an alternative to wood for building structures, but it is not as expected. Copper can also be used to craft many new items, including buckets, doors, fences, and more.
