Abstract
An improved mechanical pencil, consisting of a handle and a mechanical tube, characterized in that the inner tube is split in two longitudinally at the end corresponding to the tip, both halves of the split tube having a tendency to separate due to its spring elasticity, the inside of said two parts in section forming a circle and the exterior of said two parts forming an oval in such a way that the two parts seen in section represent two thin sickles whose tips are somewhat spaced apart from each other.
