Every model builder has their own set of favorite tools that they collected over many years of making. Owning your own set of tools is essential. It gives you access to a specific workflow that you can trust and produces the results you want.
One good piece of advice is to buy tools when you need them and not in advance and to look around to see what tools others use!
The ‘essentials’ list should provide an overview of things you need to start model building. Once you progress on your journey, you might want to consider items on the list ‘for the ambitious maker.’ Owning tools and caring for and maintaining them will extend your capabilities and deepen your understanding of how the tangible world is put together substantially by raising awareness of the interconnection between idea and realization.
