Welcome to Granton Medical's Ragg Tuning Forks website
We are the sole UK manufacturer of Tuning Forks and we have been making tuning forks in Sheffield, England since the 1840's. Since this time our forks have become the standard for accuracy and best quality workmanship.
In addition to our traditional John WalkerTM tuning forks for the Music trade, we manufacture tuning forks under the RaggTM name for Medical and Scientific industries worldwide and in recent years a new market has emerged for Alternative Healing Therapy.

Healing Therapy Tuning Forks
Vibrational sound has long been known to be a potent source of healing therapy. Sound and frequency are now recognized and used in a large range of applications within the fields of conventional and complementary medicine. Our tuning forks resonate not only at their tuned frequency pitches, but also contain the harmonics and rich overtones within the various combinations used according to the requirements of the human body.
