Ink Drawing: Blade design

My signature "blade" work; inspired by my love of swords and knives, I have spent thousands of hours of my life drawing such designs. Some now exist as tattoos, others have been commissioned for expanded works that adorn feature walls in collector's homes. A simple yet striking pattern that is often identified with the tribal designs that have become a trend in the past decade or so, the arc and sweep of each line is actually a calligraphic angle that is normally achieved with a nib pen. I started drawing such patterns when I was learning calligraphy at age 15. Using dip pens and quills, other effects could be achieved with spade nibs and dipping the actual feather in ink.
