Traditionally, a Yant is tattooed using a long bamboo stick with a split sharpened point like a quill called a Mai Sak or alternatively a long metal spike known as a Khem Sak. There are many designs of Yant available, each chosen to give either protective powers or good luck in business or in love. Many of the designs are universal but the Mantras may differ according to the Tattooer.Sak Yants, so popular in Thailand, have attracted the interest of people in many other parts of the world who come to Thailand to receive a Yant including such well known people as Angelina Jolie and Brad Pitt.
