Description

The new Gravitas Pocket Raw Copper is an ultra-portable fountain pen built for life on the move. Now in its upgraded version featuring Delrin sleeves (soft posting / improved cap seal) and ACME threads, this version along with Raw Brass skip the passivated coating, allowing a rich patina to form over time—each pen becoming uniquely yours. For a shiny look you can use a jewellers cloth to bring back the fresh copper.

Its triple-start cap opens in just 1.5 turns and features a flat side that works as a roll stop. Post the cap, and the Pocket transforms into a full-size writing instrument. A stainless steel 304 section with micro-machined grooves offers a secure, comfortable grip while keeping the weight balanced.

Equipped with a size 6 steel nib (compatible* with Jowo No. 6 generic steel nib units) available in : Extra Fine, Fine, Medium and Broad, each Pocket comes with a standard cartridge converter. Tough, compact, and endlessly personal, this is a pen that evolves with you.

*when swapping for a different nib unit you are sole responsible for checking the fitment of the new nib - we are not responsible for fitment or any damages that may occur from the instalment/use of non gravitas nibs/nib units.

Note: Brass and Copper naturally develop wear marks and color changes with regular use. In the process of packing we handle these writing instruments which may arrive on your side with more or less visible patina - this is a natural process which doesn't consist in a call on warranty or replacement

Great Pocket Pen

This is a pocket pen you can carry in your pants pocket. There is no clip, so you can’t clip it to your shirt pocket (with or without pocket protector). It’s kinda heavy, so you want to make sure it doesn’t fall out of whatever you carry it in. And finally, its outer shell is made from solid copper, a relatively soft metal that’s not particularly scratch, impact, or corrosion resistant. The copper will discolor quickly from humidity, as well as moisture and other chemicals your fingers have on them when you touch the pen. Your fingers will rub off some of the darker oxidized copper, leaving brighter shinier spots wherever your fingers habitually touch the pen. And let’s not forget about the oligodynamic effect that compounds and amalgams containing copper have on microbes! Not quite as effective as vaccines, but close.
In addition to the darkened and spotted appearance, my pen has also accumulated some scratches from posting the cap. I can’t write with the pen without posting the cap on the back of the barrel, because it’s a pocket pen, designed to be short enough to fit a pants pocket. I accept the scratches and spots as “comes with the territory”, just like having room for only one standard international cartridge, or the supplied mini-converter.
And here’s where I found an unexpected shortcoming: ink flow, specifically the lack thereof. I’ve used several of my nearly 100 different colors and brands of ink in the mini-converter. Almost all of them started to cause ink starvation sooner or later. I was able to replicate this phenomenon by using the mini-converter in one of my Sentry pens, where I also saw ink starvation. Similarly, ink cartridges cause ink starvation. With the mini-converter, you can at least “push” more ink into the nib unit to continue writing, but squeezing the cartridge may cause the cartridge to split, which allows air to get in through the crack, which causes flooding of the nib…
Surprisingly, Pelikan 4001 Königsblau has provided the most consistently positive results, regardless of the size of the cartridge or converter. Surprising, because that ink is generally not known for superior performance or outstanding characteristics, but I’ve had no ink flow problems with it in any of my pens.
Writing with the Pocket Pen is a very “forgettable” experience, and I mean that in the best way possible. Provided you fix or don’t have any ink flow problems, the Pocket Pen is very smooth and consistent, allowing you to concentrate on what you’re writing rather than constantly fidgeting with your writing instrument to get it to write. After finding the perfect ink for your needs, this pen will most likely outlast you 🙂, even with daily use.

Another Great Gravitas Pen

I ordered this pen even though I’ve had some issues with two of my six Monster pens—which amounts to a failure rate of nearly 30%. One of my Monsters (black aluminum) suddenly started leaking after three months of regular use (with Artisan Pastellier Rose Cyclamen ink; it still leaks in small amounts, even though I haven’t used that ink in it for months and am now using the fountain pen with GvFC Viper Green; otherwise, the pen works reliably). Unfortunately, two service requests regarding this issue went unanswered.

The other one (TiSinX titanium) is now, unfortunately, completely unusable, as every time I fill it, large amounts of ink immediately ooze out in thick drops from the same spot (though this could be due to using Diamone Desert Rose—I didn’t initially know that such inks might cause problems). I may contact Pen Venture at a later date regarding the purchase of a replacement ink reservoir (if possible with Ultem).

I haven’t had any problems so far with the Ultem Monsters or the Gravitas Exclusive Rainbow Skittle Monster.

The Vac 2.0, which is what this review was actually supposed to be about, is another great pen. Unfortunately, the Diamine Lady Grey ink I bought along with it seems much too dry for this pen, so I screwed in the gold nib from my Gravitas x Kyuseido Kakari, and now it writes like a dream; ironically, the original nib now writes just as beautifully in my Ultemate Vac - so I guess I have to review the new steel nib separately.

The Kraken filling mechanism works extremely well again and feels almost a bit more powerful in this pen than it does in the Monster; and the new ink window is a joy as well.

It's extremely well balanced and although I very much enjoy the girthier (and heavier) monster, fast note taking is kind of more comfortable with this pen—although, purely for aesthetic reasons, I actually like the flat ends of the Monster a little better.

However, there’s a minor flaw (which definitely isn’t due to the new gold nib, since it also occurred with the original nib) that happens when the ink reservoir is full and you screw the Kraken mechanism shut. Sometimes a large drop falls onto the paper then, but I suspect this can be prevented by simply not letting the reservoir get completely full.

That aside, the pen is a pure delight.

The broad nib I orderd it with is pure delight as well. It's nicely soft and writes very consistently with my (fairly standard, I guess) 50° writing angle. The line width is very consistent, which is a nice experience, given that many broad nibs these days have stub-like characteristics. Interestingly, this nib has this kind of character when using it in reverse for very, very small margin notes—something I haven't come across before with round-ground nibs. I kind of like it.

All in all another great and beautifully designed pen - but only time will tell if it's prone to the same problems as some of the Monsters.

The ordering process and shipment was smooth and seamless as always with pen venture and I received my ordering within just a few days. Emy added a kind handwritten note, a Monster maintenance tool and vial of silicon oil.

That creates a kind of personal shopping experience—which is something, also given that the store appears to be expanding quite rapidly.

I love this pen. As usual the Gravitas did not disappoint me. Perfect machining, absolutely perfect fit and finish.. this pen is another masterpiece. I love writing with it, I love the materials, and I love how much ink it holds. just pure Gravitas, what else to say.

Fifty 4T Titan Ultem - First Impressions

Emy has just sent me the 50/40 Titan Ultem. It’s a very well balanced pen made from a variety of rugged materials. This pen will outlast me, safe to say. The first and continuing impression the pen gives is its superb machining. The fit and finish is of the highest order comparable to artisanal products made in limited numbers by engineer-designers: like musical instruments, pocket knives, tobacco pipes and wristwatches. There is no feature or detail in this pen that distracts from my pleasure in using it. I respond to the common critiques of the 50/40 in the following way: (1) There is no clip. This is true. That this is a shortcoming is not true. I don’t need a clip. My writing surface is flat so it doesn’t roll off and the pen never leaves the studio so I don’t put it in my shirt pocket. (2) The Ultem material is the color of urine. I don’t see it that way. It’s transparent canary and provides a lively contrast to the titanium. If you prefer, the clear and smoked options are also available.(3) The nib should be gold. I disagree. This steel nib is comparable to premium Swedish surgical steel. There’s nuance and flexibility in its response. And the discrete etched logo is the only product marking on the entire pen (with the exception of the pen number out of a series of 250 at the bottom of the cap). (4) It’s too expense. That is an opinion not an argument. I had no problem paying the €640.

Gravitas - Pocket Titanium Grade 5

Beautiful pocket pen.

I’m really happy with this pen. The machining on the body is really nice and the tactility of the grip is amazing. It also looks lovely.
If I had any criticism it would be that the cap doesn’t post as securely as some pocket pens but once you get used to it is perfectly useable and doesn’t affect my enjoyment of the pen.

Gravitas - Monster Aluminium | Black

Complete pile of shite

Bought a Gravitas Monster. Kept in pen sleeve in padded case. Used carefully. Treated carefully. Filled twice. Noticed ink all over my hand. No obvious problem. When home I emptied the pen and notice a thin crack in the barrel at the "turning knob" end, just before the aluminium. Now unusable. Ink seeping out. Complete waste of money. Complete crap. Either desire flaw, or poor materials or both. Watch out. Will never buy another Gravitas POS, nor from this retailer again.
