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 it's 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.
