Short answer: No. Long answer: Some forms of pencil will become obsolete, such as the #2 HB that has to be sharpened. People will just switch to #2 HB leads in mechanical pencils.
H or hb is used for lettering in ed
A No.2 pencil, but HB is softer and is used to create dark lines when drawing.
Pencils are all marked on a European system called the degree scale where H is hardest and B is blackest.Pencils can be marked as;9H, 8H, 7H, 6H, 5H, 4H,3H,2H, H F,HB, B, 2B, 3B, 4B ,5B ,6B ,7B ,8B ,9BH pencils have a higher concentrate of clay than graphite, whereas the B pencils have a much lower percentage of clay.The B pencils make soft, dark marks, whereas the H pencils have a much harder, lighter mark.The F pencil stands for fine point, which is slightly harder than the HB making it a good writingpencil.
Drawing pencils are classified by the hardness or softness. The harder the pencil, the lighter the led's gonna be. The softer, the darker. I believe the names for the pencils from harder to softer are: 6H, 4H, 2H, H, HB, B, 2B, 3B, 4B, 5B, 6B, 8B. And there might be some new ones called F and XX9. I think. Anyway, the H's are the harder, you can remember that because H could stand for "harder." The B's are the softer. And if you remember the H, then you won't need to remember the B.
HB stands for hard black.
