The origin of the leather pencil
The painter Heyman was a careless person. When he was painting, he often put the eraser everywhere. Since he did not have a fixed place to put the eraser, he thought When I use it, I don’t know where it is, and I can’t even find it. Helpless, he had to tie the eraser to the back end of the pencil. In this way, as long as he held the pencil in his hand, he would not be unable to find the eraser, and there would be an eraser available for use at any time.
One day, Hyman's friends went to visit him. This friend saw a pencil with an eraser attached, so he fixed the eraser and pencil together, designed a pencil with an eraser, and applied for a patent. ”
