Crafting Every Nichirin Sword Variant and Upgrade in Kimetsu no Yaiba
The Nichirin Sword is the central weapon in the Kimetsu no Yaiba mod, and this guide covers every known crafting path for its variants and upgrades, including the Bamboo and Cherry Blossom forms.
Base Nichirin Sword
Before you can make any of the upgraded versions, you need the standard 
Nichirin Sword. This is a shapeless recipe, meaning the order of ingredients does not matter. You will need:
Scarlet Ore x2
Scarlet Iron Sand x2
Iron Ingot x1
Place all five items into your crafting grid, and the basic Nichirin Sword will appear as the result. This sword is the foundation for the two variant upgrades described below.
Bamboo (Material Item)
There are two distinct ways to obtain 
Bamboo, and it is important to understand that this is a separate material item, not a sword on its own.
The first method is a shaped crafting recipe. Surround the Nichirin Sword with Bamboo x8 in a full ring (all eight outer slots of the crafting grid), leaving the center slot empty. This will produce the Bamboo item.
The second method is much simpler and acts as a reversal. If you already have a 
Nichirin Sword (Bamboo) (described in the next section), you can place it alone in a crafting grid using a shapeless recipe. This will convert it back into the plain Bamboo item, effectively undoing the upgrade.
Nichirin Sword (Bamboo)
The Nichirin Sword (Bamboo) is an upgraded version of the base sword, sheathed in bamboo. To craft it, you need only a single Bamboo item.
This is a shapeless recipe: place the Bamboo item anywhere in your crafting grid, and the output will be the Nichirin Sword (Bamboo). Note that this recipe does not require a separate Nichirin Sword—the Bamboo item itself is the only ingredient. This means you can cycle between the Bamboo material and the Nichirin Sword (Bamboo) freely using the two recipes above.
Nichirin Sword (Cherry Blossom)
The final known variant is the 
Nichirin Sword (Cherry Blossom), which is decorated with cherry blossoms. This upgrade requires the base Nichirin Sword as a component, not the bamboo version.
The crafting recipe is shaped. You must place 
Cherry Blossoms x8 in all eight outer slots of the crafting grid, forming a complete ring, and place the Nichirin Sword in the center slot. This will produce the Nichirin Sword (Cherry Blossom).
Crafting Summary and Notes
Here is a quick reference for all recipes covered in this guide:
- Nichirin Sword: Shapeless – Scarlet Ore x2 + Scarlet Iron Sand x2 + Iron Ingot
- Bamboo (from sword): Shaped – Bamboo x8 surrounding a Nichirin Sword
- Bamboo (from bamboo sword): Shapeless – Nichirin Sword (Bamboo)
- Nichirin Sword (Bamboo): Shapeless – Bamboo
- Nichirin Sword (Cherry Blossom): Shaped – Cherry Blossoms x8 surrounding a Nichirin Sword
Remember that the Bamboo item and the Nichirin Sword (Bamboo) are interchangeable through their respective recipes. The Cherry Blossom variant, however, can only be made from the standard Nichirin Sword, so if you want both upgraded forms, you will need to craft two base swords. Gather your Scarlet Ore, Scarlet Iron Sand, Iron Ingots, Bamboo, and Cherry Blossoms beforehand to streamline the process.
