Many people assume that rubber pencils are too expensive and too thin for everyday writing because they have been made using an unbreakable chemical process. But that is not the case, and you can find many pencils that look just like their more expensive alternatives. This is because most plastic rubber in use today is made from petroleum, a byproduct of petroleum refining.
The main issue with using petroleum-based plastic is that the end-point of the rubber is the point on which it is attached. When a pencil comes into contact with an abrasive substance, the rubber material pulls away from the end of the pencil. Because the end is so close to the end of the pencil, a fine metal point will be permanently lodged in the end, which results in rough writing and a brittle end.
When pencils are made with polycarbonate resin, the end is not connected to the tip at all. Because the surface of a pencil has sharp sides and rounded ends, it is difficult for the metal of the tip to come near to the surface of the surface of the pencil. So instead of using a flexible metal tip, the polycarbonate is glued to the bottom of a pencil, which results in a pencil that is less likely to come in contact with the side or ends of any surface.
Because the end of the pencil is connected to the metal, it is much more difficult for ink or other liquids that contain lead to seep out of the end onto other objects such as paper, etc., because of the strong bond between the rubber and the metal. If you’re using lead in a pencil to make a mark like “HOT POCKET” and end up using the lead to make a mark just below the “H” then the pencil has already compromised the security of the pen, and can be lost in the recycling bin. But it also defeats the purpose of writing on paper, and most people are willing to compromise the security of their pen every now and then — but never the security of the pen itself. Most likely, people do this because of the cost of using metal pencils to mark their work area and for other purposes, but also for the convenience.
Is it legal to write on a pencil?
Unfortunately, it is not legal to write on most pens, pencils, and all other writing instruments, including your phone, computer, and smartphone. Pencils and some other writing instruments are not manufactured with removable parts (though they have been produced with removable parts
