Answer :
The statement given is true because the stone-tool traditions of the Upper Paleolithic were based primarily on blade tools which, compared to those of the Mousterian, are faster to make and are better at maximizing the amount of cutting edge from the same amount of stone.
The blade tools are made by the Upper Paleolithic people, and they were used for a wide range of activities, including cutting, scraping, carving, and engraving. They are characterized by a long, narrow shape that is produced by striking the edges of a stone core with a punch or hammerstone. These tools were made using a technique known as pressure flaking, which involved applying pressure to the edges of the stone to remove flakes of material.
