Every tool had some point in time when it was first made and such tools had not been used before that. So it all depends on what you mean by "in the past", how long ago is that "past".There are also many tools that have been abandoned and are no longer made and used, sometimes because better tools were invented that replaced them, sometimes unfortunately because the making and use of the tools were forgotten (often because the culture that made and used such tools collapsed or was destroyed in some way e.g. the Roman Empire).
Artifacts were used for a variety of purposes, such as tools, decorations, religious objects, or items of cultural significance. They help archaeologists understand past societies by providing insights into how people lived, worked, and interacted with their environment.
