Because the quality and weight of mechanical pencils and pencils are different, they are not suitable for students to use. Most mechanical pencils have a metal appearance and have a certain weight. If used for a long time, they will have an impact on the work. At the same time, the hands will become sore after writing for a long time. If the mechanical pencil is used for a long time, the fingers will become stiffer and less flexible. In addition, because the quality of mechanical pencils and pencils are different, many automatic pencils are of poor quality and break down easily after a short period of use. Even the refill is particularly easy to break. Repeated replacement will delay the progress and is not conducive to daily life. In class, the teacher does not allow students to draw with mechanical pencils.
You don’t dare to use force when writing with a mechanical pencil, and it is not conducive to drawing lines. The final drawing effect will be difficult to see clearly, so it is better to use a pencil to write. The pencil has a simple shape, is made of wood, and is relatively practical. It is not very effective in using wood, and it will not cause wood waste. It just requires more effort to sharpen the pencil. If you use an automatic pencil and don't control the strength well, the writing lead will break easily. If you don't dare to write hard, it will cause the writing to be unstable, which will affect the beautiful lines of the writing. Teachers do not allow students to use automatic pencils to draw pictures. The reason is that it will also affect your performance in drawing exams. Mechanical pencils pose great safety risks. If an accident occurs in class, the teacher is also responsible.
Pencils are smooth to use and are especially suitable for drawing. Anyone who has used mechanical pencils knows that the lead breaks easily. If you have used a mechanical pencil, you will know that in the end, pencil is more suitable for drawing. Generally, drawing paper is relatively thick. When a mechanical pencil encounters these thick papers, it will not be very smooth when drawing. If students change refills many times in class, the broken refills will eventually be scattered on the ground or on the table. I believe the teachers will be very unhappy. After a class, teachers all focus on changing pen refills. Who would want to pay attention to the class?
