What do you think is the most broadly useful Craft ability for a Rusticani?

Look, I know: build based on a concept, not on optimizing (for the record, my Rusticani that I'm asking for will probably end up being a giant-blooded baker, because I love the idea of a large man making pies). But building a Mechanical magus got me thinking: what would the most broadly-useful Craft ability actually be for a Rusticani? Which one would allow the use of the most Shape and Material Bonuses, and theoretically be able to provide a majority of virtues reasonably speaking? Personally, I think either woodcarving or jewelry, but I'm curious to here the community's opinions.
