The modification discussed centers around a particular fountain pen model, specifically altering its writing tip to achieve greater line variation. This involves taking a TWSBI 700R Vac, a vacuum-filling fountain pen known for its large ink capacity, and replacing its standard nib with one that exhibits flexible properties, allowing the user to create thicker or thinner lines by varying the pressure applied during writing. The resulting alteration creates a customized writing instrument.
This adjustment enhances the pen’s artistic potential, enabling calligraphic writing styles and adding character to everyday script. The modification can increase the pen’s value to users seeking expressiveness in their handwriting. Historically, fountain pens were valued for their ability to produce varied line widths, and this specific change aims to recapture some of that lost functionality in a modern pen design.
