Flexibility or Softness?
Hard and Soft Nibs
Most contemporary fountain pen nibs are hard, meaning they are designed to be rigid and to provide a consistent line width. Some, such as the Pilot Falcon series nibs or the Soft Fine and Soft Medium nibs created by Nakaya, are designed to be soft, meaning they provide for line width variation depending on the amount of pressure used when you write. Expanding on this, John can provide a customization for added flex to most 14k nibs, whether hard or soft.
Hard Nibs Are Smoother, Soft Nibs Scratchier
It may sound counter-intuitive to those new to the world of quality fountain pens, but rigid hard nibs almost always provide a smoother writing experience on the page than do semi-flexible soft nibs. Hard nibs are designed to slide easily across the page, while soft nibs are deliberately designed to give slightly under pressure, which provides the benefit of added line-width variation but the drawback of a less smooth writing experience. See our page on differences between hard and soft nibs for more details.
Broader Nibs Are Smoother, Finer Nibs Scratchier
In general, the broader the tipping size of a nib, the smoother it will write, and the finer the nib tipping point, the scratchier it will be on the page. With that said, rigid Fine and Extra Fine nibs can often be made to write very smoothly on the page when properly adjusted for ink flow and the end user's preferred writing pressure - see our nib tuning and optimization page for more details.
