* 1.0 Introduction

This report intends to identify five different models of Pens and writing instruments and critically evaluate each design. The report will focus on how the designs different from each other, pointing out the features that separate them from their competitors, and then compare them to each other. After this comparison, the report will construct a product design specification, (PDS) for a generic Pen. All aspects of what is required will be covered in order to produce a pen.

* 1.1 Background

As with most influential inventions throughout history, the Pen hasn’t deviated much from its humble beginnings as a design. A pen is a useful instrument that is commonly held between the thumb, index finger and middle finger with which humans have conveyed and recorded their thoughts, feelings and insights throughout history, and is responsible for the history of civilisation itself.
The first evidence that any writing instruments had been used was by the Greeks, who invented the first writing instrument that resembled a pen. “It was a sharp-pointed object called a stylus made of either bone or metal” (1). This was used to make markings in wax, because it was very easily scratched on.
