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. Improper usage can lead to breakages, whether instantaneous shears, or points of weakness that may hold for some time unnoticed but will eventually rupture.
