The Pen That Was Blessed by a Healer: Sailor's Strange and Beautiful 85th Anniversary Theta

By Saran Kittiwatthanachote  ·  May 2026  ·  7 min read

Before I knew anything about this pen's history, I just held it.

It has a weight to it that feels considered — not heavy in the way brass pens sometimes feel blunt, but balanced. The black Urushi surface has that quality unique to genuine lacquer: warm in the hand, slightly alive in a way that cold metal or polished resin never quite achieves. The red accent catches light differently depending on the angle. The clip has an unusual wave shape that I initially thought was just a design quirk. The nib has a symbol on it I didn't immediately recognise.

I turned it over. Looked at the cap finial. There's a Θ there — the Greek letter Theta, pressed into the lacquer like a seal.

Then I found out what Sailor actually did to the nibs of this pen. And things got considerably more interesting.

First — What Is Urushi?

Because if you're going to appreciate what Sailor did with this pen, you need to understand what's on the outside of it first.

Urushi is a natural lacquer derived from the sap of the Toxicodendron vernicifluum tree — the Japanese lacquer tree — and its history in Japan goes back over 10,000 years. It was used on samurai armour. On Buddha statues. On the bowls used in tea ceremonies. It is, in the most literal sense, one of the oldest finishing materials in human history.

The process of applying Urushi to a pen is not quick. Each coat must be applied by hand, then cured for 24 hours in a humidity-controlled chamber at carefully maintained temperature and moisture levels — because unlike paint, Urushi doesn't dry in open air. It polymerises. It hardens through a chemical reaction that requires specific conditions. After curing, each layer is polished by hand with fine abrasive materials before the next coat goes on. A high-quality Urushi piece can involve 30 to 50 individual layers. A single pen can take three months to over a year to complete.

The result is something that no synthetic finish can replicate. Urushi pens improve aesthetically with age — the surface grows more vibrant and transparent over years of use, developing a patina that's unique to each individual pen. Collectors call this "opening up." It's one of the reasons Urushi pens command serious prices and serious devotion.

What makes the Sailor Theta unusual among Urushi pens is the body beneath the lacquer. Most premium Urushi fountain pens — Sailor's own King of Pens included — use ebonite as the base material, which the lacquer adheres to exceptionally well. The Theta uses brass. The pen is made from lacquered brass, giving it that distinctive weight and the particular cool-then-warm quality you feel when you pick it up for the first time. It's a different pen in the hand than an ebonite Urushi pen, and I mean that as a compliment.

The Hado Story — What Sailor Did to These Nibs

In Japan in 1996, a spiritual concept called Hado (波動) was having a moment.

The word itself simply means "wave motion" — the same term used in physics for wave phenomena. But the spiritual interpretation was something different. Hado in the spiritual sense is the idea of harnessing the healing power of waves and vibration present in all things — the belief that matter emits energy frequencies that can be measured, transferred, and used to affect physical wellbeing. There were even devices that claimed to measure and transfer Hado energy. It was, in the context of 1990s Japan, a genuinely mainstream wellness trend.

Sailor got caught up in it.

For the 85th anniversary pen, Sailor asked a Hado specialist to treat the nibs. The name Theta refers specifically to theta brain waves — low-frequency brain waves associated with deep relaxation and meditation, considered highly desirable by spiritual healing proponents. The wave-shaped clip was intentional. The Θ symbol on the cap and nib was intentional. The entire pen was built around this concept.

And then Sailor's customer service confirmed it.

In a transcribed phone call documented on the Makibishi criticism site, a Sailor employee explained the process — describing how the nibs received Hado treatment and claiming the result was noticeable: a better writing experience, and also vague health benefits including improved blood flow and strengthened immune defence. These claims appear elsewhere too, including in secondary market listings for the pen, where descriptions mention similar therapeutic properties.

I want to be clear: I'm not presenting this as fact or endorsing any of these claims. Fudefan, whose research on this pen is the most thorough I've found in English, describes the picture as "a Sailor that got caught up in a spiritual trend and produced pens that were meant to offer you Theta-induced relaxation and clarity with a Hado-enhanced nib." That's a fair characterisation. There's also a Rod of Asclepius — the ancient symbol of medicine and healing — engraved on the nib alongside the Theta symbol, which feels either deeply intentional or wonderfully on-the-nose depending on your perspective.

What I will say is this: the story makes the pen. Whatever you believe about Hado, Sailor commissioned something genuinely strange and genuinely beautiful in 1996, and only 5,000 of them exist in the world. That's worth knowing about.

The Pen Itself — Design and Shape

One of the first things you notice about the Theta is that it doesn't look like most Sailor pens.

The Pro Gear, the 1911, even the King of Pens — these are recognisably Sailor: traditional proportions, classic Japanese pen aesthetics, the signature double-band gold trim. The Theta is different. It has a silhouette that's simpler and more architectural — a design that lets the Urushi surface do all the visual work without competing decoration. The result is a pen that's beautifully understated in a way that only reveals itself the longer you spend with it.

The version I have is the Black/Red Urushi. The body is a deep, almost lacquered-piano-black, and the red appears as a complement — subtle in some light, vivid in others. This is one of four finishes released for the anniversary: the pen was available in four colours, making the Black/Red one of the rarer combinations and, in my opinion, the most visually striking.

The wave-shaped clip feels intentional rather than decorative once you know the story. It's not just an unusual design choice — it's part of the language of the pen. The Θ on the cap finial is small and clean, not shouted. The box it comes in is also wave-themed, which tells you how seriously Sailor committed to the concept.

In the hand, it is comfortable in a way that genuinely surprised me. The brass body with Urushi over it gives a warmth that pure metal pens rarely manage. It's not the thinnest pen, but it doesn't feel excessive. What I keep coming back to is how settled it feels — like a pen that knows what it is.

The 21k Gold Nib — H-M Size

The Theta's nib is 21k gold — not the 14k you find on most Sailor pens at this tier, but 21k. That higher gold content makes a difference you can feel: slightly more softness, slightly more give, a nib that responds to the variations in your pressure more expressively than a firmer steel or lower-karat gold nib would.

The designation is H-M, which in Sailor's terminology means Hard Medium. It's a medium line width with the firm, responsive character that defines Sailor's nib philosophy. The Theta Club was also available with a bespoke Crosspoint nib made by Mr. Nobuyoshi Nagahara — one of the most celebrated nibmeisters in Japanese pen history — though the H-M is the nib I have.

If you've written with a Sailor before, you know the feel. That pencil-like feedback I mentioned in other posts — the sense of being connected to the paper rather than just sliding across it — it's here too. Smooth, yes, but with a deliberate quality that gives your handwriting weight and presence. It's the thing that separates Sailor from Pilot in feel, and it's the thing I keep reaching for when I want writing to feel like it matters.

The engraving on the nib face shows both the Θ symbol and the Rod of Asclepius — the ancient Greek symbol of medicine and healing carried by the god Asclepius. It's a small detail, easily missed, but once you see it in context of the Hado story, it's hard to unsee. Sailor was committing to the bit.

Does It Write Differently? An Honest Answer

You're wondering. I was too.

The honest answer is: I can't tell. And neither, it seems, could anyone else who's written with one carefully. Fudefan, whose research on this pen is the most thorough available in English, wrote: "I cannot tell the difference between this one and my other Sailor nibs. It's a great writer, as expected, but no Theta nirvana."

That's my experience too. It writes beautifully — because it's a 21k Sailor nib, hand-finished, made to the standard Sailor applies to everything they produce at this tier. Whether the Hado treatment contributed anything to that experience is genuinely unknowable, which is perhaps the most honest thing I can say about it.

But here's the thing. That doesn't diminish the pen. If anything it makes the writing experience more interesting, not less. Every time I pick this up, I'm aware that I'm holding something that Sailor genuinely believed — or at least publicly claimed — had been given a kind of energy by a healer. Whether you find that fascinating or absurd probably says something about you. I find it fascinating. I also find the nib excellent. Both things are true simultaneously, and that's the Theta in a sentence.

As for the health benefits? My blood circulation seems about the same as before. My immune system has not noticeably improved. But I've been writing more than usual since this pen arrived on my desk, and maybe that counts for something.

Should You Find One?

Yes — with caveats.

The Sailor 85th Anniversary Theta is a limited edition from 1996, with only 5,000 pieces produced across four Urushi finishes. It doesn't come up often, and when it does in good condition it commands a price that reflects both its rarity and its significance. This isn't a daily driver pen for most people — it's a collector's piece, a conversation piece, and for those who appreciate the intersection of craft and story, one of the most interesting fountain pens Sailor ever made.

If you find the Black/Red specifically in good condition — Urushi intact, nib writing smoothly, original box if possible — I'd move on it. These aren't getting more available with time.

If you want the full picture on the pen's history before you go looking, Fudefan's article remains the most thorough English-language account of the Theta and is well worth an hour of your time. The Makibishi phone call transcription, while only available in Japanese, gives you a sense of just how seriously Sailor engaged with the Hado concept at the time.

At Engeika, the Theta is the kind of pen we actively look for. If you're searching for one — or want to know more about it before you commit — get in touch.
