Way back when I was in daycare and eventually in first grade, I remember myself only using a pencil. We all did when we were so young. It's usually yellow. I do not know why manufacturers always like their pencils to be colored yellow. Maybe it's jolly looking?Anyway, back then, the pencil comes with the regular sharpeners in which you have to turn around your wooden pencil. That was the norm, and it still is today. At least that was the norm when you were so seven or eight. It was a surprise, I can recall, when I met the mechanical pencil. I was confused. Is it really a pencil? If yes, then why is it not made out of wood? What difference does it make, anyway, to have it in that form?
The answer is quite simple. I can think of two reasons to justify mechanical pencils' existence. First of all, it reduces the number of trees that have to be cut down in order to create your pencils. It is not as if the wood used in the ordinary pencil is used in a productive way, so better have it in a form that does not deplete our forests.
Another important thing to note is that mechanical pencils do not go shorter and shorter unlike the ordinary pencils when you sharpen them. It is mildly irritating to hold a pencil so short that you can hardly control your grip. At least with mechanical pencils all you have to replace is the lead of the pencil as the body may be refilled.
With these reasons in mind, it is natural to go for mechanical pencils overtime. Don't you agree?
