For plotting with Axidraw, I always reach for my Winsor & Newton Fineliner Fine Point Pen. The 1.0mm nib is ideal for thicker lines, and its ink coverage is reliable and opaque, ensuring the result is dark and easy to read. Its tip is also quite resistant, so I’m able to plot at high speed without any issues. This pen has become one of my go-to pens in creative projects requiring Axidraw plotting.
