Straight line pen (commonly known as a duck pen) — precise inking tool for clean, consistent lines Key benefits Produces crisp, uniform straight lines ideal for panel borders, speed lines, and background line work. Designed for ink line drawing; gives better control and steadier strokes than a needle pen, reducing rework and improving speed. Simple maintenance keeps the tool reliable and prevents deformation of the pen blade over time. Primary functions and compatibility Main uses: comic frames, speed lines, and background display in comic and manga inking. Also suited for general ink line drawing where straight, consistent lines are required. Works with standard inking workflows that use a pen blade secured by a set screw. Care and performance tips After each use, wipe away remaining ink thoroughly to prevent buildup and corrosion. Loosen the set screw after cleaning; this helps avoid deformation of the pen blade and preserves consistent line performance. Regular cleaning and proper handling maintain easier drawing compared with needle pens and extend the tool’s usable life. Use scenarios Comic artists: draw precise panel borders and dynamic speed lines for motion and emphasis. Manga inking: create background line displays and consistent hatching or texture panels. Ink line work: produce steady, repeatable straight lines for illustrations or refined line art. What makes it stand out Known as a duck pen for its straight-line capability; preferred by artists who need controlled, repeatable inking results. Easier handling than needle pens for many straight-line tasks, reducing hand strain and improving workflow efficiency. Maintenance summary Wipe remaining ink clean after use. Loosen the set screw after cleaning to prevent pen blade deformation. Follow these steps to keep line quality consistent and extend the tool’s life.
