The ruling pen is a fundamental tool in the world of drafting, technical drawing, and even calligraphy. This specialized pen, with its adjustable nib, allows for the creation of lines of consistent width with ink, paint, or other liquid media. Understanding how to effectively use and properly care for your ruling pen is crucial for achieving precision and longevity in your drafting work.
Understanding the Ruling Pen
A ruling pen is characterized by its two flexible metal blades that taper to a point. The medium, whether ink or paint, is held in the space between these blades. Adjusting a small screw mechanism controls the gap between the blades, thus determining the width of the line drawn. This adjustability is what sets the ruling pen apart and makes it invaluable for precise lines in technical drawings and detailed artwork.
Proper Technique for Line Work
To achieve the best results with a ruling pen, technique is paramount. The pen should be held vertically against a straight edge, often a specialized ruler with an ‘inking edge’. This vertical position ensures that both points of the pen’s nib are in contact with the drawing surface simultaneously. Drawing the pen gently along the straight edge allows for a smooth, consistent line.
The Vertical Hold
Maintaining a vertical hold is not merely a suggestion; it is essential for consistent line quality. Tilting the pen can lead to only one blade making contact with the paper. This results in uneven lines, skips, and a generally poor quality of line that detracts from the precision expected in drafting. Visualizing and practicing a consistent vertical hold will significantly improve your line work.
The Inking Edge: Your Clean Line Ally
The ‘inking edge’ on a ruler is a seemingly small detail that makes a significant difference. This edge is designed with a slight undercut or sometimes a cork backing. Its purpose is to create a tiny gap between the ruler’s edge and the paper surface. This gap is crucial because it prevents the ink from bleeding under the ruler and smudging your work.

If you find yourself without a ruler that boasts an inking edge, improvisation is simple. Attaching a couple of coins to the underside of a flat ruler effectively elevates it, creating the necessary gap. Alternatively, using a bevelled edge ruler flipped upside down can also achieve the same outcome. These simple solutions ensure clean lines even without specialized equipment.
Caring for Your Ruling Pen: Ensuring Longevity and Performance
Proper care is vital to keep your ruling pen in optimal working condition and extend its lifespan. After each use, it’s imperative to thoroughly clean the pen. Dried ink or paint can clog the nib, leading to inconsistent lines and eventual damage.
Cleaning is best done immediately after use with water for water-based media or appropriate solvents for oil-based paints and inks. Gently wipe the blades clean, ensuring no residue remains. For a deeper clean or to remove stubborn buildup, the blades can be carefully separated slightly to access the inner surfaces. Regular cleaning not only maintains the pen’s performance but also prevents corrosion and ensures it remains a reliable tool for years to come.
Conclusion
Mastering the ruling pen involves both understanding the correct techniques for its use and committing to regular, proper care. By holding the pen vertically, utilizing an inking edge, and diligently cleaning your tool after each session, you will unlock the full potential of this essential drafting instrument and consistently achieve precise, high-quality lines in all your technical and artistic endeavors.
