I found this one hole puncher at Staples for $2 that is much easier to use than a traditional hole puncher. In addition, it offers a different type of resistance versus a traditional hole puncher. Instead of gripping it with the hand, you use it with the finger tips or you could use the palm of the hand. If held properly in the hand, the resistance is similar to pinching a clothes pin. A three year old was able to use this type of hole punch without assistance.
