Smithing Transform Recipes for Netherite Weapon Upgrades
Smithing Transform recipes upgrade diamond weapons to their netherite counterparts in Jaam's Weaponry. Each recipe follows the same basic structure: a Smithing Template, the diamond version of the weapon, and a netherite ingot variant. The specific ingot type and quantity depend on the weapon being upgraded.
How the Recipe Structure Works
Every upgrade in this guide uses a Smithing Transform. The three inputs are always a Smithing Template, the diamond weapon, and a netherite ingot. What changes between recipes is which diamond weapon goes in and whether the recipe calls for a 
Double Netherite Ingot or a 
Heavy Netherite Ingot.
Weapons that use the Double Netherite Ingot are the 
Diamond Butterfly Sword, 
Diamond Saw Cleaver, 
Diamond Battle Axe, and 
Diamond Broadsword. Weapons that use the Heavy Netherite Ingot are the 
Diamond Buster Sword and the 
Diamond Greathammer.
Double Netherite Ingot Recipes
These four weapons upgrade using a Smithing Template, the diamond weapon, and a Double Netherite Ingot.
- Diamond Butterfly Sword + Smithing Template + Double Netherite Ingot =
Netherite Butterfly Sword - Diamond Saw Cleaver + Smithing Template + Double Netherite Ingot =
Netherite Saw Cleaver - Diamond Battle Axe + Smithing Template + Double Netherite Ingot =
Netherite Battle Axe - Diamond Broadsword + Smithing Template + Double Netherite Ingot =
Netherite Broadsword
Heavy Netherite Ingot Recipes
These two weapons upgrade using a Smithing Template, the diamond weapon, and a Heavy Netherite Ingot.
- Diamond Buster Sword + Smithing Template + Heavy Netherite Ingot =
Netherite Buster Sword - Diamond Greathammer + Smithing Template + Heavy Netherite Ingot =
Netherite Greathammer
Quick Reference by Ingot Type
If you are sorting materials before crafting, group your weapons by which ingot they need.
Planning Your Upgrades
Because the template is required for every recipe, you need one Smithing Template per weapon you intend to upgrade. The diamond weapon itself is consumed in the transform, so keep a spare diamond weapon on hand if you want to retain the diamond version alongside the netherite one.
The ingot requirement is the main variable. Four of the six weapons take a Double Netherite Ingot, while the Diamond Buster Sword and Diamond Greathammer each take a Heavy Netherite Ingot. Confirm which ingot your target weapon needs before gathering materials, since the two ingot types are not interchangeable in these recipes.
Once you have the template, the diamond weapon, and the correct netherite ingot, place all three into the Smithing Transform to produce the netherite weapon. The result is the netherite version of the same weapon type you started with.
