This means a smooth and soft point (2 mm) of pencil lead can be formed nearly 50 times by sharpner if the lead do not breaks. The remain part of pencil, nearly 1" can be used in pencil holder and it may give 2-3 time sharpening. A Pencil can DRAW a line of 35 k.m. length and this is the life cycle of a pencil.

A pencil is made from wood, graphite, and a metal ferrule. It begins its life cycle by being manufactured from these materials, then used for writing or drawing until it becomes too short to use. At this point, it is typically discarded and either ends up in a landfill or is recycled.
