I’m looking for a term for the kind of tools that haven’t significantly changed over history. These kind of items first uses usually date from humanity's early days, haven't changed much in form or function across the times and are still widely used.
It may be used in this way:
Needles are an example of a _______ tool.
Note: If I recall correctly, the age of the item isn't the point, and the unchanging characteristic (or little change across large periods) of the objects is far more important in the definition of this word.
Like spoons that have preserved its basic shape and function for milennia even if they are ergonomic now and the materials they are built with aren't the rocks in your yard any more.
I heard the word in a history class something like 12 years ago, so my definition may be a bit off.
