Abstract
Quick pencils consisting of a metal tube open at both ends one of which is narrowed in a conical while the other is split and provided with a ring of pressure that when narrowed this part of the pencils hurries by placing the pencil in the inside of the tube so that its tip comes out through the opening of the conical end of the tube and holding it by means of another whole pencil or of a stick that is inserted in the tube and is held by means of the pressure ring so that it tightens the pencil end inside the tapered end of the pencils.
