The S-shaped tool may be the length of the palm or the whole hand; it is available in plastic and resin styles. Practitioners use this multi-purpose option on the hands, feet, back, neck, lats, and shoulders. It has limited use on the face or smaller parts of the body due to its size.
Smaller than the S-shaped style, the wing tip is also multipurpose. With three sides for scraping and a broad shape for easy grip, this is one of the more popular gua sha tools. It is most commonly used on the chest, shoulders, legs, and smaller sections on the back. It can also be used on the hands and arms.
