The uniqueness of fountain pen nibs
	The uniqueness of fountain pen nibs
	
	Even when using the same nib type, from the same brand and with the same labeled size (e.g., fine, medium, broad), it's perfectly normal to notice slight differences in the line produced.
	
	This happens for several reasons:
- 
		
Hand-finishing and craftsmanship: Many nibs are polished or adjusted by hand, and even the most precise machines allow for tiny variations.
 - 
		
Material and flexibility: The metal used in the nib may vary slightly in flexibility from one unit to another, affecting ink flow.
 - 
		
Interaction with paper: The pressure applied, the angle of the hand, and the type of paper all influence the final result.
 - 
		
Ink feed system: The feed that delivers ink to the nib can have micro-variations that affect how much ink is released.
 
In other words, every fountain pen has its own “personality.” That’s what makes it special—not a sterile tool, but a writing companion that adapts to your hand and style.
