Autopoint was founded by Frank C. Deli, Michael M. Kaufmann, and John P. Lynn around 1920. They used the name "Realite Pencil Company." They worked with Lawrence V. Redman of the Redmanol Company to develop techniques for molding plastic bodies for pencils.
This is a more involved process than removing pencil markings. Pencil marks can be gradually adhered to natural rubber fragments by rubbing the mark with a pencil eraser (this action is what prompted Joseph Priestley to give solidified latex its common name). Ink, however, readily penetrates the fibers of most papers and is therefore more ...
Pencils with sub-millimeter leads can usually hold multiple leads at the same time, reducing the frequency of refills. One exception was the Pentel 350 E, possibly Pentel's first mechanical pencil, [14] which could only hold a single stick of 0.5 mm lead. Refill leads can be bought in small tubes and inserted into the barrel as needed.
Erasers may be free-standing blocks (block and wedge eraser), or conical caps that can slip onto the end of a pencil (cap eraser). A barrel or click eraser is a device shaped like a pencil, but instead of being filled with pencil lead, its barrel contains a retractable cylinder of eraser material (most commonly soft vinyl).

Pencil milling is a cleanup toolpath generated by computer-aided manufacturing (CAM) programs to machine internal corners and fillets with smaller radius tools to remove the remaining material that are inaccessible with larger tools used for previous roughing, semi-finishing, and finishing toolpaths. The name comes from the way that a pencil ...
A disposable version called Erasermate 2 was subsequently introduced, with an appearance similar to the non-erasable Write Bros. stick pen, except for a slightly larger girth, and of course the black eraser, affixed to the pen's cap. The eraser, similar to that of a standard no. 2 pencil, was about 5 mm in diameter, and 10 mm in length.
