hard black
The order of hardness goes:9H 8H 7H 6H 5H 4H 3H 2H H F HB B 2B 3B 4B 5B 6B 7B 8B 9B hard medium soft
If you mean what HB stands for, it's an indicator for the hardness (H) or softness (B) of the graphite and clay used. However, the B is for blackness so HB is like average/medium grade so the full form would be Hard Black, Hard and Black, or Hard Blackness. If you check out pencils like 3H, you'll notice that the tone when writing or drawing is light compared to an HB. Conversely, a 3B pencil will give you a darker tone.
the mechanical pencil will write better because it has a skinnier lead, so the pencil doesn't go flat if you write too much on one side. the lead also still graphite, but has special substances in it to help you write better. Still, if your pencil is certified HB#2, it can be used on Scantron Genuine Forms and State tests.

i think you mean HB, Many pencils across the world, and almost all in Europe, are graded on the European system using a continuum from "H" (for hardness) to "B" (for blackness), as well as "F" (for fine point). The standard writing pencil is graded HB. According to Petroski, this system might have been developed in the early 1900s by Brookman, an English pencil maker. It used "B" for black and "H" for hard; a pencil's grade was described by a sequence or successive Hs or Bs such as BB and BBBfor successively softer leads, and HH and HHH for successively harder ones. As of 2009, a set of pencils ranging from a very hard, light-marking pencil to a very soft, black-marking pencil usually ranges from hardest to softest as follows.

An HB pencil is just a No. 2 Pencil HB stands for Hard Black
The number "621" printed on a Nataraj pencil typically refers to the pencil's grade or hardness level. In the case of Nataraj pencils, "621" usually indicates that the pencil is of standard HB (hardness and blackness) grade, which is commonly used for general writing and drawing purposes. The number system helps users identify the pencil's specific characteristics, such as lead hardness and darkness, making it easier to choose the right tool for their needs.
I don't quite understand what you mean by HB-2 pencil but if you mean HB pencil / #2 Pencil it is not the softest pencil. Pencils scale from 9H to 9B, (HB in the middle) and 9B would the softest and darkest pencil there.
Hard Black pencil.
HB stands for "hard black" and is a designation used to indicate the hardness and darkness of the graphite core in a pencil. The HB pencil is commonly used for general writing and drawing purposes.
Nataraj
HB 2 pencil has a slightly softer lead than a regular HB pencil, which gives it darker markings. The "2" in HB 2 stands for the American grading system, while the regular HB is based on the European grading system. Both are commonly used for general writing and drawing.

The easiest pencil to erase on the market is a mechanical pencil with HB lead.
No on a pencil stands for Number. It is a measure of hardness, similar to the HB scale.
A No.2 pencil, but HB is softer and is used to create dark lines when drawing.
