Forgive me if this has come up before, but I think it would be awesome if there were some way to upgrade tools (especially grinders and cooking tools!) With several skills already, the amount of wear on certain tools is lessened, but with cooking tools and the like, you can't see how much wear is even happening. It's also kind of annoying doing street project work, and your saucepan/pot/blender/etc breaks every 10 units!
It could be a tinkering activity to upgrade, involve alchemy for better metals, come automatically when you complete the skill tree, or just have different levels of equipment available for different prices. Like a budget set, mid-range, and titanium-plated or something. Anywho, just a thought. :)
