The tuning forks I use for energy work - they are tuned to one version of the ancient and natural solfeggio scale. The handles are also painted with the equivalent rainbow color, which enhances their energetic quality, and makes them easy to identify during an energywork session.
Tok Sen is a traditional bodywork technique practiced in the north of Thailand. It has an oral tradition going back as long as acupuncture in China. The tools are hand made in Chiang Mai by local craftsmen, and are blessed by a monk. Tok Sen is a great technique to use as part of other forms of bodywork, particularly Thai massage.
