You know, I really wanted to make a thread dedicated to random questions so that members could make queries and find out interesting tidbits of knowledge… but now, I’m debating if I should go along with the idea…
Anyhow, about the No. 2 pencils, they seem to be the standard for those SCANTRON machines (I think that\'s what they are called). I don’t know if this is true or not, but I remember being told once that No. 2 pencils have enough carbon within the lead so that these machines can read them properly. Now, the question of why the masses went along with using No. 2 pencils instead of No. 1 or No. 3 is beyond me.
I am positive that other types of pencils exists. I once found a No. 3 pencil, though my experience with it was for a short time frame. If one were to compare using a No. 3 and a No, 2 pencil on paper, the lead from the No. 3 seemed much lighter than that of the No. 2, and the No. 3 seemed to last longer than the No. 2 ( the lead didn\'t get used up as much and so it didn\'t need to be sharpened a lot). I liked it so much that I primarily used it for drawing. Nowadays, I kinda wish I had another one…
