Stone Pen Workshop

Beyond its presentation, this flex pen is individually and expertly tuned for improved nib alignment, ink flow, and capillary contact… creating a smoother and more dependable writing experience. Its soft flex fine nib delivers expressive line variation from 0.4mm to 2mm, adding both precision and personality while maintaining graceful control.

Its brass-bodied construction and balanced snap-cap design lend the pen a substantial, reassuring feel in hand. With its polished presence, thoughtful tuning, and graceful writing performance, the Stone Pen Workshop modified Jinhao X450 offers a luxurious blend of artistry and function.

By pairing this dependable body with a German #5 nib that we grind, tune, and test write here at Stone Pen Workshop, you’re paying for what you actually feel every day: the way the pen starts, how it glides, and how your handwriting looks.

Steel, Geometry, and Craft At the heart of the pen is a German-made Nemosine No. 5 stainless steel alloy nib that we reshape into a fine cursive stub. The stainless steel blank is thicker and stiffer than most generic steel nibs, so the tines stay aligned and don't slowly spread or flex out of tune. That controlled hardness lets us grind the tipping into a precise edge that gives you broad, shaded downstrokes and fine cross strokes without scratchiness, skipping, or surprise "soft spots." Each nib is inspected and aligned under magnification, filled with ink only once for lubricated testing, ground and polished through multiple grits, and then test written on paper with real ink here in our Daytona Beach workshop.

The result is an Edison nib that lays down a thin, precise cross-stroke and a broader, expressive down-stroke. This complex geometry rewards careful writers and transforms everyday handwriting into something worth noticing.

The Edison #6 with a 1.1 Stub Nib is a German-made JoWo nib blank... then at Edison (before it comes to us), individually ground, aligned, tuned, polished, and purposefully tested in their workshop, not on a production line. Every critical detail has been checked and adjusted:

Tine spacing for consistent ink flow, edge rounding so the nib starts immediately without hesitation, and tip geometry calibrated for both slow, deliberate letterforms and a faster, more natural note-taking pace.

A stub nib is sort of the opposite of a fine nib. It’s ground flat and wider where the nib touches paper, so that you get line variations depending on the angle you are writing at. It’s closer to something like a calligraphy nib, and you can get some pretty nice swoops and lines with practice. When done well, the pen responds to the angle of your hand, varying line weight naturally as you write, without any additional effort or technique on your part. Good for note-taking, journaling, and note-writing,

Most fountain pens ship from a factory floor where nobody writes with them… this one left a workshop where someone spent days on it.

Oscar, our dedicated nib craftsman, took this Jinhao 82 and replaced the stock nib with a German Nemosine 1.1mm #5 steel stub, then ground it on whetstones and mylar to create clean, controlled line variation, firm on the upstroke, expressive across the page.

He aligned the tines for proper ink flow, checked everything under magnification, micro-polished the tip, and then wrote with it until it passed the final inspection. It's a craft to hand-tune, hand-test, and get fountain pens ready to write.

The brand on the cap doesn't matter here. What matters is that our expert prepared this pen the way most manufacturers never bother to because they produce at scale. We don't.

Every critical detail is checked and adjusted tine alignment, ink flow, and edge rounding so the pen starts easily, resists skipping, and feels confident whether you write slowly and deliberately or at a faster, note-taking pace. It is ground in such a way that it writes with varying degrees of line thickness based on your writing angle; it writes with a thin downstroke and a thicker cross stroke. This complex grind is something few nib crafters can achieve.

The Naginata Togi nib lays down a smooth, consistent line that works beautifully with all types of speciality inks, from shading and sheen to shimmer and intense saturation.
