What Is the Importance of Learning the Parts of a Fountain Pen?

An essential step in your journey of using this type of pen is understanding the fountain pen anatomy. Some reasons why this is important include:

Fountain Pen Anatomy

parts of fountain pen

A fountain pen has six major parts that are further subdivided into smaller, useful bits. They are the:

  • Cap
  • Barrel
  • Nib
  • Feed
  • Section
  • Converter

1. Cap

This is what covers the nib of the pen. You can write with the cap on or off. One of the advantages of writing with the cap on is the balance it gives to promote a better ink flow.

However, leaving the cap on wears it out, and it could crack or break. So it’s important to keep this in mind before choosing what to do with the pen’s cap.

2. Barrel

This is one of the most important parts of the fountain pen. It is the long part of the pen that holds the ink and protects the cartridge and converter.

The barrel comes in various materials, including plastic, wooden, or aluminum, giving a wide range of choices. Most pens keep their weight on the barrel, making it nice and heavy, while others are light to hold.

It is essential for you to choose the most comfortable one for you. This is where buying your pen in person comes in handy — you can choose the one that feels right.

Other parts of the fountain pen housed in the barrel include:


There are thin slits inside that hold the pen cap to the pen’s body. These are called threads. 


This is the part of the barrel where the threads meet the body of the pen. They work together to hold the pen together.


This is the part of the barrel where the ink reservoir is located. At the end of the body is a metallic trim ring that serves an aesthetic purpose.

3. Nib

This is the main part of the pen responsible for writing. It is the metallic end that touches the paper. It’s also the part where you put pressure on to write. The more pressure you put on it, the more ink comes out.

This is perhaps the most fragile part of the pen, and you must be careful and gentle with it.

The nib comes in a wide range of shapes and sizes. The size of the nib you choose depends on how you want your writing to appear.

Usually, bigger sizes are more suitable for people with big handwriting. The reverse is the case for people with smaller writings. On the nib, you will find:


The nib has two tines separated at the breather holes. These tines taper at the end to form the nib tip that comes in contact with the paper.


The slit runs vertically from the breather holes and carries the ink from the feed to the tip.

Nib Tip

It’s made from hard-wearing metal, usually an iridium alloy, that is welded to the nib’s end. The nib tips have specific sizes that affect the line width created.


This is the widest part where the nib begins to taper towards the tip. 

Breather Hole

This is also sometimes called a vent hole. It is a hole at the end of the nib slit that allows air to influence the ink flow. 


This is the part of the nib that is engraved with the size, brand, and model of the pen.


This is where the other part of the nib meets with the other section of the pen.

4. Feed 

The feed acts as a passage for ink to flow from the reservoir to the nib. On the feed, you’ll find:


These are the feed’s widest parts that fit snugly into the nib shoulder. Sometimes, you can slide the nib over the wings to connect both parts.


These are small, thinly cut pieces that act as ink regulators. They allow the ink to saturate the air channels and control the consistency of ink flow, especially when writing speed is varied.

Ink Channel

This very thin opening in the feed allows the capillary action needed for ink flow.


The end part of the feed goes into the ink reservoir and collects ink for the feed channel.

5. Section

Apart from this being where your fingers are placed to control the pen when writing, it also holds the nib and the threads attached to the barrel. 

6. Converter

This holds the ink of your pen and allows you to draw ink into the pen. It uses a small filing mechanism, usually a screw-piston, to draw ink. Most pens have a built-in converter, while others don’t. You might need this if you use bottled ink.


Knowing the parts of your fountain pen will help you get the most out of the experience. This will especially come in handy when you need to use tips and recommendations for your fountain pens.

We’ve put together an extensive guide to help you identify the different parts of a fountain pen anatomy. Hopefully, this helps.
