The geometric term for the tip of a pen is a "point." In geometry, a point is a location in space that has no size or dimensions, represented by a dot. It is the most fundamental element in geometry and serves as the building block for all geometric shapes and figures.
The English word for chopsticks is chopsticks.
This could vary depending on the pen, but it would most likely be a right, circular cone, frequently with the tip removed.
