Kaweco Fountain Pen Nibs

Refresh, renew, and refine your writing with a genuine Kaweco replacement nib. Sometimes a new nib is all it takes to fall in love with your favorite fountain pen again. Kaweco’s modular nib system makes it easy to swap line widths, replace a worn tip, or experiment with different writing styles without buying a new pen. This collection features authentic Kaweco fountain pen nibs, including the popular 060 nib units, designed to keep your pen writing smoothly for years.

If your current nib feels too broad, too fine, or simply worn after years of use, swapping the nib is often easier than replacing the entire pen. Kaweco’s modular design makes it simple to adjust your writing experience while keeping the pen you already love. A small change in nib size can completely transform how your handwriting looks and feels.

Compatibility is the most important factor when choosing Kaweco nibs. Checking your specific pen model before purchasing helps ensure a smooth swap.

Kaweco fountain pens generally fall into three common Kaweco fountain pen nibs:

• Screw-In Nib Units (060 Series): These are complete assemblies that include the nib, feed, and threaded housing. They simply unscrew from the grip section and can be replaced in seconds. This style fits many metal-bodied Kaweco pens, including the AL Sport, Brass Sport, Steel Sport, AC Sport, Liliput, Special, Student, Dia2, and Elegance.
• Friction-Fit Nibs: Pens such as the Classic Sport, Skyline Sport, and Frosted Sport use a fixed housing. Instead of unscrewing the entire unit, you gently pull the nib and feed straight out of the section to swap them. Using a small piece of rubber or grip material can help if the nib feels snug.
• 250 Nibs: Larger Kaweco models, such as the Supra and Elite, use the Kaweco 250 nib, which is designed specifically for those pens and is not interchangeable with the 060 system.

Pro Tip: If you aren't sure which version you have, look at your pen's grip section. If you see two small notches on the rim of the housing, it’s a screw-in unit.

Kaweco replacement nibs are available in several sizes, allowing you to customize your writing style and line width.

• Extra Fine (EF): Best for small handwriting, pocket notebooks, and thin paper.
• Fine (F): The Kaweco fine nib is the "Goldilocks" size, perfect for everyday note-taking.
• Medium (M): A smooth, wet writer that brings out the true color of your ink.
• Broad (B) & Double Broad (BB): Ideal for signatures, ink shading, and those who love a bold line.

Kaweco also offers calligraphy and stub nib options, allowing writers to experiment with expressive line variation without investing in a completely new pen.

Kaweco replacement nibs are made from durable stainless steel produced in Germany.

• Standard Kaweco Nibs: Reliable, durable, and available in multiple finishes (chrome, gold, or black) to match your pen’s trim.
• Kaweco Premium Nibs: These Kaweco premium nibs receive additional hand-finishing and stricter quality control. They feature larger tipping material (often referred to as “iridium grain”), which helps produce a smoother, more refined writing feel straight out of the box.

Ink choice and paper quality can also influence how any nib performs, so experimenting with combinations can further tailor your writing experience. Explore our Kaweco inks collection to find bottled inks and cartridges that pair perfectly with your new nib.

Replacing Kaweco fountain pen nibs on compatible models is straightforward. Simply unscrew the Kaweco nib unit, install the new one, and reassemble your pen. In the case of the plastic Classic or Skyline Sport pens, pull the nib and feed straight out of the fixed section housing and insert the new nib and feed the same way. It’s best to clean and dry the pen before swapping to avoid ink residue. In most cases, the entire process takes less than a minute and requires no special tools. Whether you’re experimenting with a new line width or refreshing a well-loved pen, genuine Kaweco fountain pen nibs make customization simple and reliable.
