I would use the aspect system for that.
If you want something transient that will give you a momentary advantage then you are maneuvering. If you want it to be more permanent then you start inflicting consequences (mild for a scene or two, moderate for the session, and severe for several sessions). Finally if you want the item to forever be something else then you would need to take it out so that you could remake it.
I'm aware however that it's an object, and thus has no discipline or endurance to resist with. The book still says that things are good at being what they are, so I'd still have it resist. Personally I would either have the GM roll using a set "I'm a wooden table" skill, or just give it an appropriate difficulty/resist score. Probably a base of great, with some things being harder (things that are more "solid") and others being more flexible.
