Copper Extensions
by dastan.d
Copper Extensions adds copper armor, a sword and a set of copper tools for Forge and NeoForge, released under All rights reserved.
What it does
Copper Extensions adds a complete set of copper equipment: a sword, a pickaxe, an axe, a shovel, and four armor pieces (helmet, chestplate, leggings and boots). The items are crafted from copper and follow the familiar tool and armor roles, so copper can serve as a mid-tier material between stone and iron progression in a survival world.
Because the mod runs on client and server, both the server and every player need it installed. Files are published for Forge and NeoForge across three game versions: 1.20.1, 1.21.1 and 1.21.8. The latest Forge file is 1.0.0 for 1.20.1, in the alpha channel, and the latest NeoForge file is 1.0.2 for 1.21.8, in the beta channel. The author states that more versions will follow.
The project is licensed as All rights reserved, so the code is not open source and redistribution terms are not granted by the license. The mod was first published on 2026-06-14 and last updated on 2026-08-05.
