The "lead" in drawing pencils has various grades or hardness.
The hardness of a drawing pencil is designated by a number and an H. The higher the number the harder the pencil is, the slower it wears done, the longer it retains its point, the less it smudges and the lighter the line is that is drawn. For example, 6H pencils are harder than 2H pencils.
The softness of a pencil is designated by a number and a B. The higher the number the softer the pencil is, the faster it wears down, the easier it is to smudge and blend, and the darker the line is that is drawn. For example 8B pencils are softer than 2B pencils.
There is a standard, middle of the road pencil, the HB pencil, sometimes called the Number two pencil. This has some of the drawing qualities of both hard and soft pencils and in a pinch will serve for most drawing and writing needs.
very hard
Pencils with H are harder, pencils with B are softer. The higher the number with the H, the harder the lead (usually light, very precise line). Pencils with B are softer, and the higher the number, the softer the lead (very dark, blurs easily).
To prevent a pencil led from fading is to not bare down so hard on the paper.
i like to use a good lead pencil number 1 because the lead isn't as hard as a number 2 pencil and therefore is easier to shade with. Good luck with your drawing!
It's really not advised to target the solar plexus as this can cause serious problems for the heart or lungs and sometimes may lead to death.
very hard

because Lead is a very hard material
No because it is hard lead
Lead is so dense it is as hard as rock, so it is very hard to write with them. And also, it's very toxic. Pencils now contain graphite, which is just a form of relatively harmless carbon. However, people still call them "lead".

Hard water contains a lot of ions , which can lead to the build up of limescale.
