Graphite is likely to break along its planes of weakness, resulting in cleavage fractures. These fractures occur because of the structure of graphite, which is composed of stacked layers held together by weak van der Waals forces. When a force is applied perpendicular to these layers, they are easily separated, causing the material to break cleanly along these planes.
both break in one preferential direction
Generally it's made of graphite. Graphite is a substance made of carbon. The carbon atoms are bonded together in a particular way that allows "sheets" of graphite to break off easily. When you write something, some of these sheets break off and end up on your paper.
most likely its discovery wasn't documented until 1889
Graphite has a perfect cleavage along its basal planes, which are parallel to the hexagonal crystal structure. This allows graphite to easily split into thin, flat sheets.
Graphite is often mistaken for lead due to their similar appearance and use in pencils. Both graphite and lead leave behind marks when drawn on paper, but graphite is the actual material used in pencils, not lead. The misconception likely arose from historical confusion stemming from the use of the term "pencil lead" to describe graphite writing instruments.
Graphite would most likely display cleavage due to its layered structure, which allows the mineral to easily split along flat surfaces.
Breaking a piece of graphite into smaller pieces does not break the chemical bonds between the carbon atoms in the graphite. The bonds between carbon atoms in graphite are strong covalent bonds within the layers of graphite. Physical forces are involved in breaking the graphite into smaller pieces, not chemical bond breakage.
There are a few advantages of using a bamboo fly road over the typical graphite fly rod. Bamboo rods are heavier than graphite rods which makes them easier to cast. They are also less likely to break and handcrafted from natural materials.
easier than diamonds, harder then graphite

In for form of graphite it can be broken into graphene sheets. In other forms carbon does not break into sheets.
Graphite will break apart through cleavage, which means it will split along flat surfaces parallel to its crystal structure. This is because graphite has a layered structure with weak bonds between the layers, allowing them to easily slide past each other.
it is very likely for a condom to break

The mineral you are referring to is likely graphite. Graphite has a nonmetallic luster, is black in color, and has a low hardness that allows it to be scratched by a fingernail.
