Our forks are made by a manufacturer in America. We specialize in high quality, low cost tuning forks made from a non-rusting, non-tarnishing, non-magnetic aluminum alloy. They are made out of aerospace aluminum with a mix of titanium, zinc and magnesium. They are designed to produce a pure tone even after many years of use, with proper care. The tuning forks range from 26 hertz (or beats per second) to 5,000 hertz. Our forks also have longer stems (2.3" to 2.5" and longer with lower frequencies) to allow for ease with body work. We do carry the standard stem 2" along with the 2.5" long stem of the 128 hz. That is due to an academy that uses the standard stem. 

The forks are machine cut and are precisely tuned within 0.5% at 20 degrees Celsius of the indicated frequency. Because of special aluminum alloy used to make the fork, they are resistant to decreased frequency changes due to temperature fluxations and are harder and more durable. They come with a lifetime warranty. Abuse of the forks is not coverered. Therefore, it is suggested that they not  be struck on any hard surface, dropped or exposed to the heat or cold for an extended amount of time.
