A flex nib (or flexible nib) fountain pen has a special nib design that allows the tines of the nib to curve and spread apart when pressure is applied during writing. The nib’s flexibility produces varying line widths that can add character and beauty to handwriting or calligraphy.
The shape of a flex nib is different than that of a regular fountain pen nib. The flex nib tines are longer and thinner to allow for more flexibility. Flex nibs must be used carefully! If too much pressure is applied to the nib during writing this can cause permanent damage to the nib.
The degree of flexibility varies among flex nibs. True “superflex” or “wet noodle” nibs are no longer manufactured and exist only in vintage fountain pens. Flex nibs found in modern fountain pens are considered to be “semiflex.” These have less flexibility but are easier to use and more durable than their vintage superflex cousins. To get the most flex out of a modern nib, an expert nibmeister can be hired to modify a nib to create a more flexible writing experience.
When writing with a flex nib you will need to practice, take your time and write more slowly than you would with a regular fountain pen nib. The fountain pen ink you choose to use will affect your writing experience since ink properties vary, so don’t be afraid to experiment with different inks. Noodler’s Ink has created a couple of inks specifically designed for use with a flex nib: Black Swan in English Roses and Black Swan in Australian Roses. Be sure to get yourself some good quality paper such as Rhodia or Clairefontaine.
Some examples of modern semiflex nib fountain pens include:
- Namiki Falcon Fountain Pen
- Pilot Metal Falcon Fountain Pen
- Platinum 3776 Century Fountain Pen with a Soft Nib
- Noodler’s Ink Ahab Flex-Nib Fountain Pen
