Ever stumbled upon an odd-looking gadget at a flea market or in your grandparents’ attic? Many obscure devices once served niche purposes, from measuring shoe sizes in stores to manually duplicating keys. Today, while many are obsolete, some collectors and hobbyists still use or restore them for fun, historical interest, or display.
Others have found new life in the maker and DIY communities. For example, old scientific tools or analog measuring instruments are often repurposed for educational projects or retro-style art. The charm of these items lies in their uniqueness and mechanical ingenuity.
