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 Stone Pen Workshop, 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.

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.

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.

• 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 Stone Pen Workshop 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 Stone Pen Workshop, 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 Stone Pen Workshop, 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 Stone Pen Workshop 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. • You 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.
