This Delrin whistle is precision made in exactly the same way as our metal whistles but using Delrin, a new modern polymer developed for food contact applications. Delrin is now the material of choice for precision instruments where strength & performance are critical and because it is completely sterile and stable at extreme temperatures.
It is especially valued for its rigidity and toughness. We also find it to be pleasant to use even on very cold mornings. The Derin has an excellent variety of clear crisp tones and is the perfect choice for anyone who does not want to use a metal whistle.
