Teachers use chalk to get a better grip on the chalk or they will not chalk on their hands. They also use Where a breach of chalk in two or three small sections. I'm looking for something similar to a pencil of China.

At least, it's a brand name. You can find them in art supply stores on the avenue pencil and they are great to get a grip on a pencil truncated. They adjust so you should be able to mount a grease pencil is fine.
