I believe that the crafting will be limited/similar to the same style and approach as we have seen in FO3. You click on the
workbench forge, select the recipe 'Iron Shortsword' from your list, 3 iron ore nuggets and 1 piece of leather are removed from your inventory and shabang-bang-bang-> Iron Shortsword was added to your inventory.
If it turns out to be more diverse/immersive/interesting, I will be very happy. If it turns out to be the same as in FO3, I won't be disappointed either as I wasn't expecting anything more
