If your fountain pen is scratchy, skips, or has a bad filling system, the right fix depends on the job. I’d use a nib specialist for tuning or custom grinds, and a vintage repair shop for old pens with filling or parts issues.
Here’s the short version:
- Basic tuning and smoothing in the U.S. often costs $25–$50
- Custom grinds often cost $60–$100+
- Modern pens are often easier to service because many use common nib sizes
- Vintage pens may need parts that are hard to find
- Do not pull the nib yourself unless the maker says it is user-removable
If I were choosing fast, I’d match the service like this:
- Mark Bacas / NibGrinder: custom grind work, like Blade, Architect, and CSI
- Mike Masuyama / Mike It Work: fine tuning for Pilot, Platinum, and Sailor
- Tim’s Tines: nib work plus vintage repair, including bladder and diaphragm replacement
- Inkpen Vintage Fountain Pen Repairs: older American pens with filling-system problems
- John Mottishaw / Nibs.com: premium Japanese pens and custom nib shaping
- Kirk Speer / Pen Realm: tuning, specialty grinds, and small repair jobs
Before I send any pen out, I’d check what the problem is, whether the pen is modern or vintage, what the shop wants shipped, and whether I need insurance.

What to Know Before Sending a Pen or Nib
Before you pick a service, get clear on two things: what’s wrong and what kind of pen you have.
Identify the Problem Before Booking
Be specific about the issue before you book. Is the pen scratchy? Does it hard start or have uneven ink flow? Is the filling system failing?
A quick look with a magnifier can help you narrow it down. Sometimes the trouble is in the nib. Other times it’s the feed or the housing. That small check can tell you if the pen needs a simple tune-up, a custom grind, or an actual repair.
Modern Pen or Vintage Pen
This matters more than most people think. It affects both what can be fixed and how long the work may take.
Many modern pens use standard Bock or JoWo #5 or #6 nibs. Those are often easier to service or replace. Some pens, like Kaweco models, use threaded nib units, so the whole assembly can be swapped.
Vintage pens are a different story. Parts may no longer be made, which means restoration can call for donor parts and extra care with older materials.
What to Send
Follow the shop’s packing list exactly. Some services want the full pen. Others only need the nib unit or the nib/feed assembly.
Shipping, Insurance, and Wait Times
If the pen has real value, use tracked and insured shipping, and keep your receipt. It’s a small step that can save a lot of stress later.
Also check turnaround time before you mail anything. Some jobs take a few days. Others can take several weeks.
Once you’ve pinned down the problem, the pen type, and the shipping details, it becomes much easier to compare services and see which one fits the job best.
1. Mark Bacas – NibGrinder
Mark Bacas, under the name NibGrinder, is known for precise tuning and custom grinds for people who want a nib shaped around the way they actually write. This is a tuning-first service. It’s a strong fit for nib performance and custom line shape, not structural repair.
Service Focus
He adjusts flow and tine alignment to match your grip, pressure, and writing angle. He accepts both modern and vintage pens.
Repair and Grind Range
His best-known offering is the Blade grind, a specialty grind that changes line width based on writing angle. He also offers Architect, Cursive Smooth Italic (CSI), and Needlepoint grinds, along with flow adjustment, tine alignment, and smoothing.
This service makes sense for writers who want a highly customized writing feel, not just a basic tune-up.
Turnaround Theme
NibGrinder works from a waitlist. You book first, then ship your pen when your spot opens up. Check the current queue before booking, and include your preferred ink and paper so the final setup matches how you write.
If you need broader repair or restoration, the next entries move from specialty tuning into deeper service work.
2. Mike Masuyama – Mike It Work
Mike Masuyama, who works under Mike It Work, trained in Japan and spent more than 20 years as a Sailor Pen Company nib technician. His work centers on precise tuning and custom grinds.
Service Focus and Grind Range
If you want careful tuning for Japanese pens, Masuyama is a strong match for Pilot, Platinum, and Sailor pens. His most well-known option is the Needlepoint grind, which creates an extremely fine, smooth line. If you aren't sure which tip is right for you, use a nib size calculator to find your preference. He also offers Cursive Italic and Architect nib grinds, plus tine alignment and smoothing.
In plain English: this service is best for precision nib performance, not structural repair.
Turnaround Theme
Work moves through a queue, so turnaround time can vary. This makes his service a good fit for writers who don't mind waiting for detailed work on Japanese nibs.
If you need broader restoration or repairs for vintage pens, the next services cover a different kind of work.
3. Tim's Tines
Unlike the tuning-only specialists above, Tim's Tines also takes on vintage repair work. Tim Girdler handles nib tuning, custom grinds, and repairs for older pens.
Service Focus
For vintage pens, he replaces bladders and diaphragms. He also offers while-you-wait service at major U.S. pen shows.
Repair and Grind Range
Tim's main work includes nib smoothing, flow adjustment, and custom grinding. This is a good fit for scratchy nibs, skipping, and poor ink flow.
4. Inkpen Vintage Fountain Pen Repairs
When an older pen needs more than a basic tune-up, Inkpen focuses on full mechanical restoration. Inkpen Vintage Fountain Pen Repairs is a good match for vintage American pens, especially ones with tricky filling systems. Joel and Sherrell Hamilton work on older pens with complex mechanisms, which makes them a solid choice when a vintage filling system starts to fail.
Service Focus
Inkpen focuses on preservation-first mechanical restoration. The goal is to get the pen working again while keeping its historical character intact. They often work on models like Parker Vacumatics, Parker 51s, and Sheaffer Snorkels.
Repair and Grind Range
Inkpen is mainly for restoration work, not custom nib grinds or basic tuning. If your pen needs a filling system overhaul or an older mechanism brought back into working order, this is the service to look at.
Turnaround Theme
Turnaround time depends on the model, the condition of the pen, and how much work the mechanism needs.
5. John Mottishaw – Nibs.com
After restoration work, this entry shifts back to precision customization. Nibs.com (Classic Fountain Pens) offers nib tuning, custom grinds, and repairs for common nib issues, with a strong focus on Japanese pens such as Nakaya, Sailor, and Platinum.
Service Focus
Best for precise nib work on premium Japanese pens.
Repair and Grind Range
Services include tuning, smoothing, flow adjustment, and grinds such as Stub, Cursive Italic, Architect, and Spencerian flex.
Turnaround Theme
Turnaround varies by job, so this is a better fit for planned custom work than an urgent repair. In plain English, if you want a nib shaped to your writing style before it goes back into daily use, this is a strong option.
6. Kirk Speer – Pen Realm
Kirk Speer of Pen Realm is a strong pick for writers who want custom nib work and help with small repairs. His work centers on performance nib grinding, precision tuning, and minor fountain pen repairs, with a clear emphasis on nibs that write better, smoother, or in a more specialized way. Proper maintenance and cleaning can often prevent the need for such repairs.
Service Focus
Pen Realm is best known for specialty grinds like the "Secretary de Flex", which adds flexibility to modern nibs, and the "Tomahawk" grind.
Those are the headline options, but they’re not the whole story. If you want a pen tuned to write more cleanly or shaped for a certain feel on the page, this is the kind of shop many fountain pen users look at first.
Repair and Grind Range
Alongside those signature grinds, Pen Realm also offers standard grinds and minor repair support. pricing starts at $25 for tuning and $45–$65 for custom grinds.
That pricing puts the service in a range that makes sense for people who care about how a pen writes day to day, not just how it looks in a case.
Turnaround Theme
Turnaround usually runs 2–8 weeks, so it’s smart to plan ahead if you need your pen back by a certain date. The comparison below helps match each service to the kind of work you need.

The big split here is pretty simple: some of these services focus on nib tuning, while others lean into vintage repair work. If you're looking for a lower-cost place to start with a new pen or nib instead of a repair job, the next section covers where Fountain Pen Revolution comes in.
Where Fountain Pen Revolution Fits In
If you want a low-cost pen to practice on before booking repair work, Fountain Pen Revolution is a good fit.
It’s not a nib repair service. Instead, it sells affordable fountain pens for beginners, nibs, ink, stands, and cases. That makes it useful if you want a pen you can learn on before sending in one that matters more.
Starter sets begin at $35.
Final Takeaway
Each service above fits a different kind of nib problem. The right pick comes down to the issue, the value of the pen, your budget, and how long you're willing to wait.
Simple flow, alignment, or line-width problems usually call for tuning or a custom fountain pen nib. Once the issue goes past that, you're no longer looking at basic tuning. You're looking at repair.
High-value and vintage pens need a steadier hand and deeper experience, especially when parts or filling systems come into play. If the pen has real value, specialization matters more than speed.
FAQs
How do I know if my pen needs tuning or repair?
Your pen may need tuning or repair if it feels scratchy, skips, hard-starts, or lays down uneven or heavy ink. In many cases, the cause is pretty simple: misaligned or uneven tines, a gap between the nib and feed, dried debris in the slit, or a problem with the slit or tip.
Start with a thorough flush, then let the pen dry fully. After that, inspect the nib with a 5x–10x loupe.
If the problem is still there, or if you spot cracks, a sprung nib, or missing tipping, it’s time to get professional help.
Should I send the whole pen or just the nib?
Usually, it’s best to send just the nib or nib unit. For tuning or common writing issues, that’s often all the service needs. Things like alignment and ink flow can usually be checked without the full pen.
Send the whole pen only when the issue involves the feed or fit, when the nib unit is hard to remove, or when there’s structural damage. If you’re not sure, contact the service first and share your pen model and nib size.
Is it safe to mail a valuable vintage fountain pen?
Yes - if you take the right precautions. For rare or high-value pens, professional repair is often the safest choice.
If you need to mail your pen, buy extra insurance on top of the standard coverage, which usually covers only $50.00. Pack the pen with care to help avoid damage in transit. And if the pen is rare or collectible, it’s smarter to use a professional nibmeister instead of trying a DIY fix.
