Abstract

A beveled writing pole includes a top portion, a beveled portion, and a throat portion. The top portion has an end that defines a writing pole tip. The beveled portion adjoins the top portion and has a bevel that extends from the writing pole tip and increases a thickness of the writing pole proximate the pole tip. The throat portion is formed of the top and beveled portions and has tapered sides that extend from the writing pole tip and increase a width of the writing pole proximate the writing pole tip. A method of forming the beveled writing pole is also presented.
