Tungsten Carbide Scribe and Magnet

This is a great tool for use in the field.  Often also called a geology scriber or magnetic pen, it is great for exploration geologists.  It's used to scratch rocks to gauge hardness and also to check for magnetic properties on the other end.  The tip is made of tungsten carbide steel so is super hard. It can also be used to mark rock specimens, or indicate orientation, specimen numbers, etc...

Very handy tool, essential for any professional or student.  Comes with a cap as pictured.  Often called a rock scratcher or rock scriber. 

Essential for iron ore exploration for detection of magnetite and magnetic BIF (Banded Iron Formation) which poses significant safety hazards due to the increased risk of fibrous materials when undertaking RC (reverse circulation drilling).
