What Is the HB Pencil Used For?
HB sits in the middle of the pencil hardness scale, giving a line dark enough to read easily while staying firm enough not to smudge quickly, which is why it is the usual grade for school writing. Pupils use it for handwriting practice, arithmetic, sketching apparatus and specimens in lab notebooks and answering worksheets, and its marks can be erased cleanly when a correction is needed.
Because it also writes on plastic slates, the same pencil serves early-years classes that switch between slates and exercise books. The six-sided casing stops it rolling off sloping desks and gives small hands a steady grip. Schools buying from a school science kit supplier in India often add a class set of HB pencils to kit orders so pupils can record observations during practical work.
