Upgraded builds specifically the ink converter
Here is the deeper, “modder‑level” reasoning tailored to our builds:
Short takeaway:
We include a stainless-steel spring coil inside each converter for fountain‑pen ink agitation:
Your stainless spring coil should be 8–12 mm long inside a Jinhao‑82‑sized barrel. That length gives you the best balance of ink movement, bubble breakup, and zero flow interference.
Optimal coil length for ink agitation (Jinhao 82 / Century 100 scale)
1. The sweet spot: 8–12 mm
This length consistently gives:
Enough mass to jostle ink during writing
Enough surface area to break surface tension
Short enough to avoid touching the converter piston
Short enough to avoid rattling against the barrel wall
...
For your stainless coils (0.2–0.3 mm wire), this is the “Goldilocks zone.”
Why not shorter? < 6 mm coils:
Don’t generate enough turbulence
Don’t break bubbles reliably
Tend to sit at the back of the converter and do nothing, as they’re basically decorative at that point.
Why not longer? > 14 mm coils
Risk scraping the converter wall
Can wedge diagonally
Can interfere with piston travel
Increase drag → slower ink return → starvation on fast strokes
We’ve probably seen this when tuning 1.1 stubs (or architects) that need consistent feed replenishment.
Coil geometry matters more than length
Here’s the modder‑level breakdown:
Pitch: 1.0–1.3 mm Wider pitch = better agitation, less mass
Diameter: 4.5–5.0 mm Perfect for Jinhao/Majohn converters
Wire gauge: 0.2–0.3 mm stainless Enough mass to move, but not enough to scratch
If you want maximum agitation with minimum risk, use: 5 mm diameter × 10 mm length × 1.2 mm pitch × 0.25 mm wire
That’s the “pro” spec many custom makers quietly use.
Bonus: How coil length affects ink behavior
Short coil (6–8 mm)
Gentle agitation
Good for wet inks
Minimal noise
Best for shimmer inks (less settling)
Medium coil (8–12 mm) — optimal
Strong agitation
Best for everyday inks
Prevents micro‑bubble formation
Helps keep feeds saturated on wide nibs
Long coil (12–14 mm)
Maximum agitation
Can cause cavitation in dry inks… Cavitation does not normally occur during standard fountain pen use; instead, users usually experience surface tension trapping ink or normal air bubble formation.
Understanding Cavitation vs. Common Converter Issues
True Cavitation: This is the rapid formation and violent collapse of low-pressure vapor bubbles in a liquid (caused by extreme local pressure drops or high-speed mechanical forces), which does not happen under normal fountain pen writing speeds or capillary action.
Surface Tension ("Ink Hanging Up"): Ink often sticks to the back of a converter due to surface tension rather than a vacuum or vapor pocket collapse.
Air Bubbles: Normal negative pressure draws air back into the chamber as you write, creating visible air pockets rather than physical cavitation. [1]
If your pen is experiencing ink flow issues, let me know the model of your fountain pen and converter as well as the specific symptoms (skipping, hard starts, or leaking)
Risk of piston interference
For our nib/feed setups
You’ve been tuning:
1.1 stubs
#5 feeds widened for architects
Stainless nibs (304/316) with high spring back
These setups benefit from medium‑length coils (10–12 mm) because they:
Keep the feed wet during fast journaling
Reduce starvation when the nib geometry demands high flow
Prevent bubble lock in narrow Chinese K5 converters
If you want, I can also give you a flow‑tuning chart that correlates coil length with feed channel depth, including specs for anti‑cavitation coils for shimmer or iron‑gall inks
Best Majohn converters for Jinhao 82/100
1. Majohn K5 Standard Converter
Push‑fit mouth matches Jinhao feed nipple
Correct internal diameter (~5 mm)
Correct insertion depth
No piston interference in either pen
Smooth piston, good seal
Reliable for everyday inks and wet nibs
This is the converter Stone Pen Workshop uses when upgrading Jinhao pens. It’s the best converter upgrade for both pens.
Bottom line for your Jinhao 82/100 builds is that a Majohn K5 will give you:
Fewer skips
Fewer hard stops
Better flow
Better shimmer handling
Better agitation‑coil compatibility
Cleaner ink draws
Longer converter life
Next blog we’ll discuss tell me which Majohn K5 have the best QC, whether the metal‑collar K5 is worth it, and how to tune your converter for maximum flow... especially how we pair converter + coil + feed for our artisan-crafted fountain pen.
The real, practical answer grounded in your Jinhao 82 experience and the Majohn Chinese‑pattern K5 does fit, and yes, it can meaningfully improve writing performance.
Below is the modder‑level breakdown tailored to your artisan workflow.
Will a Majohn K5 reduce skipping and hard stops in your Jinhao 82?
Yes — in most cases, you’ll see noticeably fewer skips and hard stops... and here’s why:
1. Better seal means better ink delivery
Majohn’s K5 has:
A tighter push‑fit collar
More consistent nipple diameter
Less wobble at the feed junction
This improves capillary continuity between converter → feed → nib. Skipping often comes from micro‑air leaks at the converter mouth; Majohn’s tolerances reduce that.
2. Smoother piston → fewer starvation events
Majohn’s piston:
Moves more smoothly
Doesn’t “stutter” when ink is low
Doesn’t trap bubbles as easily
This keeps ink flowing during fast strokes, especially with your stubs and architects.
3. Less bubble lock
Jinhao OEM converters often trap a bubble at the top of the reservoir. Majohn’s internal bore and piston geometry reduce bubble formation, which directly prevents hard stops.
Additional benefits you’ll notice
1. More consistent flow on wide nibs
Our 1.1 stubs, architects, and tuned #5 nibs demand higher flow. Majohn’s K5 feeds them more reliably.
2. Better shimmer performance
If you use shimmer inks:
· Majohn’s smoother bore
· Less turbulence at the piston
· Better agitation compatibility… all help keep particles suspended.
3. Cleaner ink draw
Majohn converters tend to:
· Draw ink more evenly
· Avoid partial fills
· Reduce the “half‑fill” problem common in Jinhao OEM units
4. Better compatibility with agitation coils
Your stainless coils (10 mm × 4.8 mm × 0.25 mm) work perfectly inside Majohn K5 converters:
· No scraping
· No piston interference
· Strong agitation
· Zero rattle
This is not true for all Jinhao OEM converters.
5. Less rattling inside the barrel
Majohn’s K5 has slightly better barrel clearance in the 82 and 100, reducing noise and vibration.
6. Longer lifespan
Majohn’s piston seals last longer and don’t crumble or stiffen as quickly.
When a Majohn K5 won’t fix skipping
If skipping is caused by:
Under‑polished tines
Misaligned nib
Starved feed channel
Overly dry ink
Paper absorbency issues… a converter upgrade won’t solve it. But for converter‑related skipping, Majohn K5 is the most reliable fix.
Bottom line for your Jinhao 82/100 builds
A Majohn K5 will give you:
Fewer skips
Fewer hard stops
Better flow
Better shimmer handling
Better agitation‑coil compatibility
Cleaner ink draws
Longer converter life
It’s the best converter upgrade for both pens.
If you want, I can also tell you:
Which Majohn K5 sellers have the best QC
Whether the metal‑collar K5 is worth it
How to tune your converter for maximum flow
How to pair converter + coil + feed for your artisan pen line
Pertinent specifications we adopt:
These are the specs that matter for our builds:
Majohn K5 Converter (Chinese K5 Standard)
· Mouth type: Push‑fit
· Mouth diameter: ~3.4–3.6 mm (matches Jinhao feed nipple)
· Internal bore: ~4.8–5.0 mm
· Piston travel: ~14–16 mm
· Material: Clear polycarbonate body, stainless piston rod
· Seal quality: Medium‑high (better than Jinhao OEM)
· Agitation coil compatibility: Excellent
· Fit: Perfect in Jinhao 82 and Jinhao 100
*This is the converter that supports your stainless agitation coils and your tuned nibs.
Why the Majohn K5 is part of your near‑term goals
1. Flow stability improves immediately
Majohn’s piston and bore geometry reduce:
· bubble lock
· starvation
· mid‑stroke hard stops
· inconsistent flow on wide nibs
2. Better seal → fewer skips
The push‑fit collar is tighter and more consistent than Jinhao OEM.
3. Perfect match for your agitation coils
Your optimal coil spec:
· 10 mm length
· 4.8 mm OD
· 0.25 mm wire fits flawlessly inside Majohn K5 converters.
4. Cleaner ink draws
Majohn converters fill more reliably and avoid the half‑fill problem.
5. Higher QC → better customer experience
If you’re building an artisan pen brand, converter reliability is part of perceived quality.
6. Works across our entire product line
One converter standard simplifies:
· inventory
· assembly
· tuning
· customer support
The Bottom line
Yes — the Majohn K5 is a part of your near‑term goals. It’s the correct converter for our Jinhao 82/100 builds, it supports our agitation coil engineering, and it improves writing performance in ways Stone Pen workshop customers will feel immediately.
PAPER for FOUNTAIN PENS
15 August, 2026 · StonePenWorkshop
Paper for Fountain Pens
Best paper for fountain pens?
The best paper for fountain pens depends on your personal preferences, but here are some StonePenWorkshop top recommendations:
...
Top Picks
•Sakae TP Iroful Loose Leaf Paper: Known for its special surface treatment, this paper brings out the best in fountain pen ink, with crisp writing and minimal feathering and bleed-through.
•Tomoe River Paper: A benchmark for ink shading and sheen, Tomoe River paper is super smooth and loved by fountain pen enthusiasts. Look for notebooks like Colorverse Nebula Tomoe River or JetPens Tomoe River 52 gsm Kanso Noto Notebooks.
•Rhodia Paper Pad: Rhodia's paper is celebrated for its smoothness and resistance to feathering and bleed-through, making it ideal for fountain pen use.
Other Great Options
•Clairefontaine: Smooth 90gsm white paper with no feathering or bleed through, available in various binding options and formats.
•Itoya Profolio Oasis: Smooth 75gsm cream-colored paper with no feathering or bleed-through… perfect for writing, journaling, and designing.
•Midori MD Notebooks: Known for their high-quality paper and binding, Midori MD notebooks are a favorite among fountain pen enthusiasts.
Considerations
•Dry Time: Look for papers with fast dry times, like Maruman Mnemosyne (3-5 seconds) or Kokuyo Yu-Sari (15-20 seconds), to minimize smudging.
•Paper Weight: Lighter papers (50-70 gsm) can show more feathering and bleed-through, while heavier papers (80-100 gsm) provide more stability.
•Smoothness: Smooth papers like Tomoe River and Rhodia provide excellent writing experiences.
At StonePenWorkshop, we spend a lot of August doing exactly that—testing new nib profiles, refining flow, and pushing small adjustments that make a big difference on various papers. It's a reminder that even small changes in setup can completely transform the writing experience.
July always feels like a reset button
06 July, 2026 · StonePenWorkshop
July always feels like a reset button.
The pace shifts, the days stretch out, and there's finally room to slow down just enough to enjoy the act of writing again—not just writing with a pen, but actually experiencing it. Time to decide if you like a little feedback. At Stone Pen Workshop, July has become one of our favorite times to revisit penmanship and put new tools through their paces.
...
Many pen company nibmakers offer a 1.1 mm stub grind; however, stylish writers shy away from ornamental lettering and find the 0.6 mm stub provides just enough line variation to give your handwriting personality, turning ordinary notes and daily entries into something a little more artful. It rewards good penmanship with a bit of elegant contrast between thick and thin strokes, while still remaining readable and practical for journaling, note-taking, and thoughtful writing.
If you've been rotating the same daily writer for months, this is the perfect time to change things up. Warmer weather tends to favor lighter inks, smoother flows, and nibs that feel effortless across the page. A well-tuned medium or stub nib, especially with a wetter profile, can bring out shading and character in summer-friendly inks—think light blues, soft greens, or even dusty oranges. These combinations not only look great but make longer writing sessions feel less like work.
July is also ideal for practicing penmanship without pressure. You don't need a formal system—just consistency. A page a day is enough. Focus on letterforms, spacing, and rhythm rather than perfection. Switching between different nib grinds can actually accelerate improvement. A crisp italic will expose inconsistencies in your strokes, while a smoother round nib helps build confidence and flow. Both have their place on the desk.
This is also the season to experiment with pens that might not make your regular rotation. Maybe it's a budget model you've been meaning to tune, or a nib you weren't sure how to use. Summer is forgiving. There's more time to test, adjust, and even make mistakes. Some of the best-performing pens in our lineup started as simple experiments during slower months.
At StonePenWorkshop, we spend a lot of July doing exactly that—testing new nib profiles, refining flow, and pushing small adjustments that make a big difference on paper. It's a reminder that even small changes in setup can completely transform the writing experience.
A Quartet of Voices... Four Grinds, Every Occasion

A Quartet of Voices... Four Grinds, Every Occasion
Every writer carries within them more than one voice.
•There is the voice of a quiet Sunday morning, unhurried and reflective.
•There is the voice of a brisk Tuesday letter, purposeful and precise.
•There is the romantic's voice, and the architect's voice, and the voice of someone whose hand drifts naturally sideways, following some inner compass the rest of the world cannot quite read.
So if you've been meaning to improve your handwriting, explore a new nib, or just reconnect with the reason you enjoy fountain pens in the first place, now's a good time to start. Keep it simple. Keep it consistent. And most importantly, enjoy the process.
Crafted for journalers... an expressive writing instrument
26 May, 2026 · StonePenWorkshop
Refresh your writing: try a new pen, or a new way to use it.
This attractive ice-seagreen polished resin pen is crafted for journalers who want an expressive writing instrument without sacrificing everyday usability. A new Century 100, not exactly a pocket pen, is substantial in the hand (posted or not) and fitted with a 0.6 German steel alloy stub nib from the renowned top-tier nibmaker Nemosine (Berlin-based)… then deftly tuned, touched up, and polished in our Stone Pen Workshop. It offers a writing experience that is both distinctive and dependable.
...
Many pen company nibmakers offer a 1.1 mm stub grind; however, stylish writers shy away from ornamental lettering and find the 0.6 mm stub provides just enough line variation to give your handwriting personality, turning ordinary notes and daily entries into something a little more artful. It rewards good penmanship with a bit of elegant contrast between thick and thin strokes, while still remaining readable and practical for journaling, note-taking, and thoughtful writing.
Unlike a plain fine nib, this stub has a more italic-like character, making each word feel deliberate and refined. Yet it remains forgiving in use, gliding smoothly across the page as you lay down your thoughts. The result is a pen that feels uniquely yours: smooth, expressive, and well-suited to the rhythm of everyday writing.
A Quartet of Voices... Four Grinds, Every Occasion

A Quartet of Voices... Four Grinds, Every Occasion
Every writer carries within them more than one voice.
•There is the voice of a quiet Sunday morning, unhurried and reflective.
•There is the voice of a brisk Tuesday letter, purposeful and precise.
•There is the romantic's voice, and the architect's voice, and the voice of someone whose hand drifts naturally sideways, following some inner compass the rest of the world cannot quite read.
...
The extraordinary gift of the nib grinder's art is this: there exists a ground nib for every one of those voices.
The Stub is where most writers begin this conversation — and with good reason. Its rectangular tip, softened at the corners into gentle rounded edges, produces broad, confident downstrokes and whispering-thin crossbars without demanding anything of the writer.
No special angle, no disciplined slow hand — just the natural motion of writing, suddenly made elegant.
The stub is the grind for everyday beauty: for the journal left on the nightstand, the letter slipped into an envelope on a rainy afternoon, the signature that carries just a little more weight than the moment expected.
•It imparts calligraphic flair almost as a side effect of simply being used.
The Cursive Italic… steps further into the light.
Its corners are sharper than the stub's — not unkindly so, but meaningfully so — and the line variation blooms with it: downstrokes grow bolder, crossbars grow finer, and the contrast between the two becomes a kind of visual music.
Yet the cursive italic forgives speed. It was made for writers who want drama in their script without surrendering fluency, who write in long connected sweeps rather than measured calligraphic deliberation.
•It is the grind of the passionate correspondent, the diarist who fills pages without lifting the pen, the writer who wants their handwriting to announce itself.
The Crisp Italic… takes that drama to its logical extreme.
Here the edges are squared, the tipping reduced, the contrast between thick and thin pushed to its highest ratio.
It is a formal instrument — the pen of the calligrapher, the scribe, the person who slows down because they want to slow down, who finds that discipline and beauty are the same thing.
•Each letterform becomes an event. Each stroke lands with authority. A crisp italic does not merely record words; it pronounces them.
The Oblique
is something altogether more personal. Its tip is angled — typically between 15° and 20° off the horizontal — to meet the paper squarely for a writer who naturally rotates their pen as they move across the page.
Where a standard grind might skew and lose its line variation for such a writer, the oblique keeps faith with them, delivering smooth, consistent stroke contrast tailored to the geometry of their particular hand.
•It is, in every sense, a bespoke instrument — the grind that says: "I was made for the way you write, not the way someone else writes."
Together, these four grinds form a complete vocabulary of mark-making:
•From the approachable warmth of the stub to the sculpted authority of the crisp italic, from the fluid expressiveness of the cursive italic to the intimate attunement of the oblique, they offer every writer… at every speed, in every mood, for every occasion…
•A pen that does not just carry ink, but carries intention.
We emphasize good quality control
01 May, 2026 · StonePenWorkshop
German and Chinese steel nibs use the same foundational stainless steel composition, but differ in manufacturing precision, quality control (QC), and tipping materials.
Base Steel Alloy
Both German and Chinese nibs typically start with austenitic stainless steel—specifically alloys like X2CrNiMo18-14-3 (similar to the well-known 18/8 chromium-nickel steel) containing approximately 65% iron with chromium (18%), nickel (14%), and molybdenum (3%).
...
•This alloy is chosen because it's non-magnetic, has low carbon content for weldability, and can be work-hardened during cold-rolling, increasing yield strength from around 240 MPa to 760 MPa—critical for proper nib elasticity.
Manufacturing and Quality Differences
Rather than fundamentally different alloys, the distinction lies in manufacturing standards and consistency.
•German nib makers like JoWo, Bock, and Nemosine maintain stricter metallurgical controls and adhere to specification requirements.
•At the same time, Chinese manufacturers show more variation in quality control and steel composition—though this doesn't necessarily mean inferior steel.
Most manufacturers, whether German or Chinese, don't publicly disclose their exact steel grade (e.g., 316 vs 304), suggesting that alloy composition isn't the primary competitive differentiator.
Tipping Material
The more significant difference appears in tipping material. German manufacturers traditionally used premium osmiridium (an osmium-iridium alloy at 30–60% osmium).
•In contrast, modern nibs from both regions now use proprietary tungsten-based alloys (tungsten-rhenium-cobalt and tungsten-ruthenium) due to cost and availability constraints.
•Chinese-made nibs sometimes carry misleading labelling, such as "Iridium Point Germany," even though they are made of tungsten alloys in China.
Since StonePenWorkshop work with various nib suppliers (JoWo, Nemosine, and Chinese options like Hongdian and Asvine), the real performance difference you've likely noticed comes down to tipping consistency and grinding precision rather than the base steel composition itself.
Chinese nibs marked "Iridium Point" or "Iridium Point Germany" seldom contain any real iridium—the markings are purely marketing. The term "iridium" has become a genericized label for any hard-tipped material on fountain pen nibs, even though modern manufacturers haven't used actual iridium for decades.
The Historical Context When fountain pens first emerged in the late 1800s and early 1900s, manufacturers tipped nibs with iridium alloys containing platinum-group metals (osmium, ruthenium, rhodium, and iridium).
•By the 1920s-1940s, manufacturers began phasing out expensive iridium in favour of cheaper alternatives—tungsten, ruthenium, and other hard alloys yet continued to call them "iridium points" because the name carried prestige.
What Chinese Nibs Actually Contain
Modern Chinese nibs marked "Iridium Point Germany" typically use tungsten-based alloys or tungsten-ruthenium mixtures—the same materials premium manufacturers use today.
•The "Germany" marking is deceptive; many of these nibs are made in China or India, not Germany.
•The key difference is that cheap Chinese manufacturers use lower-grade tungsten alloys with less ruthenium (or none) to cut costs, whereas premium nibs balance tungsten with ruthenium for better performance.
The Real Distinction
"Iridium Point" is essentially an outdated brand name that stuck. No modern nibs—whether German, Chinese, or Indian—contain appreciable iridium despite the labeling.
•The meaningful difference lies in the quality and consistency of the tungsten alloy blend and the precision of the grinding and finishing process, not whether iridium is actually present.
At StonePenWorkshop, this is valuable because we can confidently tell customers that the real quality distinction in modern nibs comes from the grind quality and the consistency of the nib material you apply during customization, not the misleading factory markings.
How do Chinese Iridium Point Germany nibs compare to real German nibs?
Chinese "Iridium Point Germany" nibs are fundamentally different from genuine German nibs (JoWo, Bock, Schmidt, Nemosine), with trade-offs in both directions depending on application.
Performance Reality
Counterintuitively, some users report that Chinese IPG nibs actually outperform JoWo and Bock nibs in reliability and hard-starting resistance right out of the box.
•German nibs from premium brands like Montblanc and Pelikan are often criticized for being "overly smoothed," with blunt tips that lack character or feedback.
•Chinese IPG nibs tend to have sharper, more defined tipping that some enthusiasts prefer, though this also makes them more prone to scratching if misaligned.
Quality Control and Consistency
Genuine German nibs from manufacturers like JoWo, Bock, and Nemosine benefit from stricter quality control in their factories, resulting in more consistent tine alignment and nib geometry.
•Chinese IPG nibs often show wider variability in manufacturing tolerances—some perform excellently, while others can be scratchy or have misaligned tines due to lower QC standards in factories.
•However, this inconsistency works both ways: excellent Chinese IPG nibs do exist and can rival German performance once tuned.
Material and Pricing
Chinese IPG nibs typically use basic stainless steel tips (not precious metal alloys), allowing manufacturers to sell them per unit wholesale.
•German nibs use precious metal alloys (platinum-group metals) that justify higher prices but aren't inherently superior in modern practice.
Note: Both use similar tungsten-based tipping material today; the "iridium" label on Chinese nibs is purely marketing.
For our Business
For StonePenWorkshop, this distinction is valuable: Chinese IPG nibs are excellent candidates for our customization workflow.
•A scratchy Chinese nib often becomes exceptional after your grinding and tuning process, while German nibs may require less correction but offer less room for improvement. Our experts' ability to smooth and tune Chinese nibs to premium performance gives us a significant cost arbitrage advantage over resellers who only stock pre-tuned German nibs.
Practical difference Grade alone doesn't tell the story: A Chinese nib marked "stainless steel" and a German JoWo #5 may both use 300‑series stainless, but the German nib's heat‑treat, grinding precision, and tine alignment are typically more controlled.
Corrosion risk: Even premium German nibs (JoWo, Bock) can corrode if exposed to iron‑gall inks long‑term; Chinese nibs may corrode faster if quality control is poor, but regular use and flushing mitigates this.
For Jinhao models, a stock Jinhao steel nib works fine for casual writing, but a JoWo #5 or #6 replacement offers noticeably better tuning, durability, and consistency precisely because of material traceability and manufacturing precision, not just "grade."
The bottom line for our StonePenWorkshop tinkering, comes down to things like when you work on a variety of say, Chinese vs. German nibs… there isn't a single "grade" comparison - it's really quality control + material specs + precision manufacturing.
That said, the more we tinker, it becomes obvious that a JoWo #5 stub will outperform a stock Jinhao nib not just because the steel might be "better," but because JoWo's tines are straighter, the tipping is more consistent, and the grind is more predictable. •The only way to find out about these things is to get "inky fingers," keep working with experts, (or at least watching their videos, podcasts and reading other's experiences).
Bottom line for Stone Pen Workshop fountain pen tinkering… Chinese vs. German isn't a single "grade" comparison—it's really about a) quality control, b) material specs, and c) precision manufacturing. •A JoWo #5 stub will outperform a stock Jinhao nib not just because the steel might be "better," but because JoWo's tines are straighter, the tipping is more consistent, and the grind is more predictable.

Compatible Pens for Nemosine #6 1.1 Stub
Budget Workhorses
The x750 and x450 are the go-to test beds for Nemosine stub swaps - solidly built, #6-compatible, and inexpensive enough to use as everyday carry pens. Several Moonman and Chinese ebonite models round out the budget tier with the same #6 footprint.
Performance Modification Platforms
Tesori Venezia and similar Bock-#6 resin pens are well-regarded Nemosine homes once paired with a Bock feed. Noodler's Konrad and Ahab accept #6 nibs and, when properly sealed and tuned, handle the wetter flow of a 1.1 stub, or cursive italic nib beautifully.
Designer-Grade Options
Select TWSBI models and the PENBBS 456/16SF bottle-fillers are popular in mod circles — both support #6 nib units and offer a more premium aesthetic for higher-tier listings. More details to follow...
"It's all in the nib..."
06 March, 2026 · StonePenWorkshop
Today on the bench I started with a stock steel nib and reshaped the tipping into a smooth, crisp stub. The goal was a wet, glassy line with just enough feedback to feel the page.
After setting tine alignment under 10× magnification, I opened the flow for a generous medium line, then finished the grind on micro‑mesh and Mylar films. The result is a nib that glides but still gives you precise control for everyday writing and signatures.
