Crafting items using the Craft skill

How does crafting work when creating mundane items in Ascendant. Lets say you have the craft (blacksmith) skill and you want to create a sword. How would that work? Do you just apply a DV to creating the sword and apply the degree of success model by applying a -3 to the RV or is their another way?

For something like a sword or other ordinary object, just treat it as if Repairing a Wrecked object. The character would just need the tools, the parts, and some Time.
