What Kind Of Tools Did People Use During The Paleolithic Era?

The same kind we will be using if the world don't get it together.
In the era you mentioned, as w/ any era before modern day, they did not have the tools and equipment we have, but their knowledge was better and starting with various rocks, they fashioned tools of wood, eventually, they had an idea and using the rocks, they fashioned a head of stone and a handle of wood, they had another idea, taking the sharp stones, cut vines and tie the stones to the wooden handle and made the first hammer.   With the hammer they fashioned and forged more tools w/ more ideas and so we now have air impact tools which are able to inflict more force on an object or idea, so on and so on.
Wereas they lived by their might (hard work), we the modern era are weak, using tools to make tools so we can sit around and do nothing but complain about the hard labor of writing a report.
To illustrate this, go to a mechanics shop for a repair and say do not do diagnostics or use computers or power tools, warning.....they'll refuse the job, or tell you insurance does not allow you to watch....lol
