Series of five photos with tools from the past. The tools in question have been used by craftsmen for hundreds and sometimes thousands of years. Due to inventions from the past century, they have largely fallen into disuse. Young people and older people often do not know what their purpose was for many tools. The plumb bob, for example, was already used in the time of the Egyptians to make perpendicular constructions. Now new (and certainly much more precise) tools are being used for this. Yet it is strange that a tool that was common among craftsmen for five thousand years is now no longer recognized by most people. The tools have, as it were, ended up in a dark past. That is why they were photographed in a dark setting.
