Choppers were also used to cut plants and plant roots, as well as cut fabrics for warm clothes and portable tent-like structures. Scrapers were also made of small, sharp stones. These turned raw hides into tents, clothing and other utilities. They varied in size and weight depending on the work they were needed for. There is evidence that groups of humans experimented with other raw materials including bone, ivory and antler, especially during the later Stone Age period.

These included bone and ivory needles, bone flutes for playing music and chisel-like stone flakes used for carving antler, wood or bone, or even artwork into a cave wall. For example, during the Mesolithic age, a flake could be a tool whose one side was used as a knife, the second as a hammerstone and the third as a scraper. Different methods of making similar tools also suggest the emergence of distinct cultural identities. Pottery was also used for food and storage. The oldest pottery known was found at an archaeological site in Japan, with fragments of clay containers used in food preparation found there dating up to 16, years old.

Some also say that it can help relieve TMJ, headaches, and sinus pressure. This is especially true for the under eye area in the morning to reduce puffiness as interstitial fluid can accumulate in these areas overnight when laying flat.

As for the mental benefits, San Pedro says, "To me, any type of self-care practice can be a ritual for you. Performing gua sha feels grounding to my spirit and inner self-care. I feel balanced when I include the ritual as a part of my skincare regime; I am breathing through the techniques and clearing [my mind]. Ready to use your gua sha tool like a real pro? It's a relatively simple process that anyone can do. It's best to perform gua sha on clean skin. If you use toner, apply it after cleansing.
