Abstract
The invention discloses a combined pencil sharpener and an ink stamp being able to give off light. The invention includes a pencil sharpener and a stamp which are slidably engaged together. When a pencil is inserted into an opening of the pencil sharpener, it will move the sharpener towards the stamp and then conduct a circuit contained in a housing of the stamp to allow an LED to give off light. The invention will not only increase the attractiveness of the sharpener but also be very helpful to teach a young user to sharpen a pencil.
