clutch compass / concept for a stationary tool

The idea behind my concept was to come up with a tool for the school children i.e. an integration between a clutch pencil and a geometrical compass. This would not only save more space in their little pencil box but also act as an interactive product which is fun to use and also serves the purpose. It is also safe because as the pointer is hidden and used only when needed. Better grip for performance adds a different feel to it. Hence you have a combination of an eraser, pencil (where you need to sharpen it anymore) and the geometrical compass which come out as a surprise factor in the product. Thus it is a product for every school student.
