[tribal light]

I want to make a custom iron sword, it make by a material that you need to blasting raw iron block. What should I do ?

AFAIK, there's no way to do so in a crafting recipe, because the recipe can't check for inputting items' nbt/custom_data/components

However, you can achive this by using floor crafting or

Yeah, or custom crafting table
Any sort of custom crafting methods

as a workaround, you can use a normally unobtainable and unusable in survival item as the base for your custom ingredient, such as a command block or structure block. then you can just use that id as the ingredient in your recipe

I will leave the product as a command block but have a custom textrue

and use command block to craft somthing like custom iron sword ?

but it only have a limit item and I want more than that

then you'll need to use floor crafting or make a custom crafter.

this would look bad in the recipe book and would cause recipe conflicts

it is bad for compatability but so are a lot of things datapacks have to do. and it's very easy to fix the recipe book by just replacing the base model of the item
