People first started inventing tools to make life easier; this meant that every single feature of a tool had a specific function. This would make sense as few raw materials were used, and everything had to be painstakingly harvested or gathered by hand. Nothing was done by accident, and everything was very intentional, and nowadays we might think tiny details in the design seem purely aesthetic, but that actually serves a useful purpose. Sometimes their role may even seem glaringly obvious, but in reality, often the product’s intended purpose is something more obscure! All of these everyday items have important functions, some potentially life-saving. Others are game-changing in terms of their usefulness.
