Paper & Ink Artsí Horizon Folded Pens are similar in function to the Ruling Writer but feature thinner, sharper edges. We based the shape of our original folded nib on a tool Michael Sull depended on for a pointed brush look while at Hallmark. Use the point for a thin line then lay down some or all of the side for broader marks of varying widths. Actually acts like a hard-edged, pointed brush; the user has more control than with a brush. Our new version makes it easier for the pen to contact the paper and allows a more normal hold. Thanks to Carl Rohrs for testing and advising us on this improved version!
