• Commit message should be more descriptive
• Groups should be plural (AXES not AXE)
• All elements annotated with @Kapi should have a javadoc
• Constructors should follow the style guidelines

 SWORDS(Set.of(
    Material.WOODEN_SWORD,
    Material.STONE_SWORD,
    Material.IRON_SWORD,
    Material.DIAMOND_SWORD,
    Material.GOLDEN_SWORD,
    Material.NETHERITE_SWORD
)),

Will be waiting for more groups other than the initial tools before merging.
here are some ideas:
Tools
Weapons
Mob eggs
Ingots
Ores
