The Tuning Bench: A Blueprint for Fixing a Scratchy Nib

In the hand, a fountain pen should feel like a precision instrument, not a rusty nail. But we’ve all been there: you unbox a new pen, fill it with your favorite ink, and the moment the nib touches the page, it digs in. It’s scratchy. It skips.

Before you relegate it to the back of a drawer or buy a replacement, stop. A scratchy nib isn't trash; it's a project. More often than not, the issue isn't the pen—it's the alignment of the tines.

Here is the technical blueprint for tuning a scratchy nib at the bench.

Step 1: The Macro-Lens Inspection

Do not touch abrasive materials to your nib until you know exactly what is wrong. You need magnification. Use a 10x or 20x jeweler's loupe and inspect the tip head-on.

Look at the two halves of the iridium tipping. Are they perfectly level? If one tine is higher than the other, the inside edge of the lower tine will catch on the paper’s fibers. This is the most common cause of a "scratchy" feel.

Step 2: Realigning the Tines

If the tines are misaligned, you need to adjust them. Mind you, this requires patience.

Using your thumbnails, gently push the higher tine down, or lift the lower tine up. Use careful pressure, hold it for a few seconds, and release. Re-check with your loupe. It is better to make ten tiny adjustments than one aggressive bend that ruins the geometry of the nib.

Step 3: Addressing the "Baby's Bottom"

If the tines are aligned but the pen still skips on the first stroke, you might be dealing with "baby's bottom." This happens when the inside edges of the tipping material are over-polished at the factory, creating a gap that prevents capillary action from pulling the ink to the page.

To fix this, you need to flatten the writing surface slightly.

Step 4: The Micro-Mesh Polish

If you need to smooth the tipping or remove a mild baby's bottom, use 12,000-grit micro-mesh.

Ink the pen (the ink acts as a lubricant) and hold it at your normal writing angle. Draw slow, deliberate figure-eights on the micro-mesh. Use zero downward pressure—let the weight of the pen do the work. Check your progress on paper every few seconds. You want to retain a pencil-like feedback, not polish the nib until it feels like writing on glass. A nib without feedback is a nib without a personality.

The Ritual of the Refill

Once the tines are aligned and smoothed, flush the pen thoroughly with water to remove any micro-abrasives. Then, enjoy the ritual of the refill. Settle in, fill the reservoir, and listen to the scritch-scratch of a well-tuned tool on 52gsm paper.
