2.5mm diameter pointed stylus, made from stone-grade tungsten carbide for fossil preparation. This stylus fits The Ammonite.

What is tungsten carbide? Stone-grade tungsten carbide is by far the best material for fossil preparation – it withstands the abrasive nature of rock and stays sharp far longer than other metals like steel which will quickly blunt and wear down to nothing. However, tungsten carbide can be brittle. A stylus can last many years without requiring replacement when looked after correctly.
