Stone-grade tungsten carbide pyrite chisel for fossil preparation, to fit the Ammonite. The straight chisel is designed for use with softer rocks, e.g. shales, softer limestones. It is not recommended for hard, brittle or well indurated rocks - we suggest purchasing the rounded chisel instead if this is what you work on. Excellent for smoothing matrix. 

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.
