Gravitas Bifrost Review: A Rainbow-PVD Fountain Pen With Real Craft Behind It

Introduction

The Gravitas Bifrost is a limited-edition fountain pen from Ben Walsh and his team at Gravitas Pens, created as a collaboration and limited to 200 pieces. At the time of writing, it appears to be sold out, so treat this as a look at what the pen offers rather than a sales pitch. Still, if you come across one secondhand or a future run appears, it is worth knowing what makes it interesting.

Design and Build

The Bifrost is a clipless, torpedo-shaped pen in frosted translucent polycarbonate, sized up next to a Pilot Metropolitan as a fairly large and girthy pen. Despite the size, it is well proportioned and comfortably balanced. The whole pen weighs 36 g, with 30 g of that in the barrel, meaning much of the remaining heft sits in the metal section.

The theme is a rainbow bridge from Norse mythology, and the rainbow PVD finish is applied consistently: the finial, barrel end, section, nib, and even the metal piece inside the converter all carry it, shifting from chrome-like to gold tones depending on the angle. The large section is ribbed and tapers before flaring slightly, which makes it comfortable for bigger hands and still pleasant for smaller ones. The small step-down near the threads is cleanly finished and not sharp at all.

Nib and Writing Performance

The pen uses a number six steel nib with the Gravitas logo, available in extra fine, fine, medium, and broad, plus a flex option. The test unit came in broad. In use, the feed keeps up well with fast writing, and the flow sits comfortably in the middle, neither too wet nor too dry. The nib showed no skips and no hard starts, with a touch of natural line variation: broader downstrokes and narrower side strokes, without any pressure applied.

Reverse writing works well too, taking the broad nib down to a finer line with no scratchiness. Line width also shifts slightly between different papers; the same pen and ink looked a touch wider on one notebook’s paper than on Rhodia.

Things to Consider Before Buying

Two practical notes before you decide. First, the pen does not post. The shape invites you to try, but the cap will not stay on the back, so use it unposted, which works fine given the length. Second, while the translucent barrel might tempt eye-dropper fans, the metal section and an internal connection point make leaking a real risk, so it is best to stick with the converter.

The balance is the real highlight here. Because the weight sits toward the section, the pen rests naturally with the heft exactly where it meets the paper. It is heavy enough to feel substantial but not so heavy that long writing sessions fatigue your hand.

Buying Advice

At $129, the Bifrost feels fairly priced for what you get. Yes, the nib is steel, but this is a pen made with personal attention rather than churned out in bulk: everything fits, nothing is sharp where it should not be, and the finish is consistent throughout. If you want a limited-edition pen with genuine craftsmanship and a distinctive theme, and you can find one, it is a solid choice. If you prefer posted pens or clip-on pens, look elsewhere.

Conclusion

The Gravitas Bifrost delivers a well-crafted, thoughtfully balanced writing experience with an attractive rainbow-bridge theme carried through every part of the pen. The only real complaint is the inability to post the cap, and that is a minor preference rather than a flaw. For fountain pen fans who appreciate detail-oriented work from a small maker, it is easy to see why these sold out quickly.
