Gravitas Piston carbon black -- their flagship fountain pen (in my opinion)

The Gravitas Piston carbon black fountain pen has it all:

- The pultruded carbon looks gorgeous and gives the pen a substantial feel in your hand even though it's relatively light. This is not a cheap pen and it does not feel like a cheap pen. You're going to love writing with this one!

- I previously assumed that I might not like the big #8 nib but once you've started using this pen you're going to love the #8

- I have this pen equipped with an extra-fine nib, and combined with the black ebonite feed it is a generous writer that lays a nice and precise line on the paper

- That grip section: made from Titanium and with extremely fine micro grooves it does not even feel like metal and it doesn't feel slippery in the least! (I own three more Gravitas pens with metal sections, two Sentries and a Pocket Carbon: The section on the "Piston" is outstanding and my favorite.)

- And finally: the piston mechanism is extremely smooth and easy-going!

... Go and buy a Gravitas Piston as long as they're available!

Very nicely crafted pen. Writes very well. Time from order to delivery was excellent. Onlu issue is that the piston does not close snug with the pen and there is always a play which is a bit of disappointment. All in all very good pen.

Amazing fit and finish on a limited release pen. The pultruded carbon fiber offer an extremely unique textural feel. The #8 size PVD coated titanium nib is smooth and very wet for a fine nib. The piston filling system is very high quality held together with precise manufacturing tolerances. Everything about this pen screams "refined".

The purchasing experience with Emy at Pen Venture is very personal. He adds a touch of flair to each sale making you feel like you are a valued customer. Pen Venture and Gravitas have both earned my repeat business.

Gravitas - Piston Carbon Black - A modern example of classic Bauhaus design and a future collectable

I recently received this pen, and all I can say is wow! The material is warm in the hand, while at the same time fits my hand perfectly! I was not only impressed with the quality of the pen, (as the fit and finishing and tolerances are better than if not comparable to the likes of Pilot/Namiki, Pelican, Mont Blanc, Lamy, or Visconti, etc.) but the pen's dimensions demonstrate a design language that reflects perfect balance and weight distribution, this is something that is rarely seen in fountain pen design.

The writing experience is sublime, with the No. #8 nib (mine is an EF) demonstrating exceptional consistent ink flow and the right amount of feedback under all writing conditions. It does not skip, stall, and does not dry out! The titanium section is perfect for my pen grip, and should easily accommodate most pen grips...

Finally, the piston fill system on this pen works flawlessly with the ink window accurately showing the ink level. All in all, I definitely recommend purchasing this pen if they are available. This pen is something that has to truly be experienced in order to understand how exceptional it truly is!!!

Awesome carbon fiber body piston FP

I love this pen in every way. I love customer service from Pen Venture. I wish this pen had a pocket clip. However, for normal daily writing I would go with this pen.

Gravitas - Monster Grade 5 Titanium & Ultem | Machined Finish
Destiny Smith
An Amazing Pen

A vacuum filler pen with the ink capacity of an eyedropper filler!
I like pens with large ink reservoirs, because more is better, especially if I'm away from my ink stash. Eyedropper fillers offer the highest ink capacity, but...if you don't have a way to shut off ink flow between reservoir and nib unit, you run into "burping" issues, which can get very messy, especially if you can't see if there's ink in the cap. The solution was either a vac filler, or a "Japanese eyedropper", both of which have a plug attached to a rod that can be screwed into the opening between ink chamber and nib unit, sealing it off. My Opus 88 and Visconti Homo Sapiens have a total ink capacity of around 3.5ml. The Monster G5 has an ink capacity of 7ml. That's like 10 Standard International Short cartridges! That means most casual users might fill their Monster 2-3 times per year. Using a Fine nib, one complete fill lets you write 450 A4 pages, or about 54,000 words. Hopefully, you REALLY LOVE the ink you filled it with, because you'll be looking at that ink for a long, long time!
But not only is the ink capacity huge, the pen itself is pretty amazing, as well. The Kraken filling system, a clever variety of a vac filler system (with an improved shut off valve) that prioritizes ink capacity, is virtually unparalleled in modern pens currently on the market. The Ultem (or clear Acrylic) body of the pen is polished to crystal clarity, the metal is highly corrosion resistant titanium, and the #8 steel nib is smooth as glass.
I'm cheap, and boring, so I do most of my fountain pen writing on plain copier paper, which allows the ink to spread out, letting a Fine nib make a line like a Medium nib. I also like to use Pelikan 4001 Königsblau, because I got a good deal on the 1,000ml bottle of ink from my favorite online seller. The combination of cheap(er) paper and ink pairs really well with the Monster's #8 nib and feed; my Fine nib makes a line comparable to a Japanese Medium nib, while keeping the color richly saturated. Using standard European 5mm quad ruled paper, the nib writes thin enough to be perfectly legible. I do have to write a bit slower, though, because the generous ink flow also means longer drying times, and writing too quickly can cause smearing issue. That's a me-problem, not a pen-problem.
The nib itself is stiff, but very smooth, meeting or exceeding the smoothness of all of my JoWo #6 steel nibs. In my opinion, the combination of nib and feed make this one of the best general purpose pens you can buy, because it will work reliably on a wide variety of paper, and a wide variety of inks. As with all demonstrator type pens, avoid "high maintenance" inks, like permanent/document/waterproof inks (and Baystate Blue), because unless you're a professional writer/author, that ink is going to stay in your pen for at least a month, and your pretty clear tank may become stained permanently.

Gravitas - Sentry Raw Copper
Destiny Smith
Hefty, and Awesome

The Copper Sentry is one of the heaviest pens on the market. However, I find that hand fatigue is hastened more by grip section than the pen's overall weight. Moreover, the pen is back-weighted, with the center of gravity resting on the web of your hand between thumb and index finger, which makes the business end of the pen much easier to move across the page. The grip section of the pen is made from PVD coated stainless steel, and tapers from around 13mm to 11.5mm in diameter, making it ideal for a large pen.
The finish is flawless and free of blemishes and tarnish, but it will accumulate micro-scratches over time. However, unlike coated or painted pens, these scratches will me much less noticeable, because there is no bright shiny metal to contrast with the colored coating.
The nib is JoWo #6 compatible, meaning that the nib unit has the same type and size of threads as a standard JoWo nib unit, and you can most likely put a different type of JoWo #6 type nib into the nib unit. However, if you do that, be extremely cautious when putting the cap back on your modified pen; if the new nib sticks out a bit further than the original nib, there's a chance that the inside of the cap may touch/damage/destroy your new nib. And I can not tell the difference in performance between the Gravitas nib and a "genuine" JoWo #6 steel nib. The nib is smooth, with barely the hint of feedback, and ink flow is absolutely perfect, even with Pelikan 4001 Königsblau ink, which is dry enough to cause ink flow problems in some of my other pens.
The clip...is still not present on Gravitas fountain pens. And there is no roll-stop, either. So...that does limit your options in how you transport your pen, and the handy black single pen zippered pouch the pen is delivered in may become your default storage and carry option. If you're considering a pen sleeve, get one with a folding flap, to prevent the pen from sliding out of the sleeve.
Last item: ink capacity. Gravitas pens are designed for Standard International cartridges and converters. Converters hold 0.5ml, Standard International Short cartridges hold 0.7ml, and Standard International Long cartridges about 1.2ml - 1.4ml. You can "refill" cartridges with bottled ink using a blunt tip ink syringe, which gives you almost as much ink capacity as a standard piston filler pen. With a little practice, you can refill your cartridges without making (much of) a mess ;-), but keep a paper towel handy, just in case.

Great service - from management of expectations, communication, delivery speed and quality packaging...and the friendly handwritten notice by Ema that did not go unnoticed.
Thank you!

Gravitas - Entry Raw Grade 5 Titanium
Luke
A solid upgrade to the Entry line

This is a nice upgrade to the original Aluminium body / steel section Entry. The capping experience is much more premium, and the whole pen feels premium too. The weight is exactly the same as the old one (both 24g on my scales inked and unposted) but the balance is more traditional as both body and section is Ti rather than a heavy steel section with light alu body. Also raw Ti has a slightly tacky feel so the section is grippier than the black coated steel which is helpful. I enjoy the high quality minimalist look of it a lot. The gravitas extra fine nib is also, unexpectedly, a joy. It is a little broader and wetter than I was expecting but has a touch of very pleasant feedback. I’m glad I got the EF as I think the F may have been a bit too much for my diary with normal paper.

For those looking to use this as a platform for swapping in Jowo nib units be aware that whilst the threads are the same the section is precision machined to fit the body of the gravitas/kanwrite nib unit which is a hair slimmer than most Jowos. Therefore some Jowo nib units will just about squeeze in and work fine, while others will not fit at all. So far two out of the three i’ve tried have fit with a little encouragement initially, but a third has not. I expect I can get that nib working in it by swapping it into a nib unit which does fit. So not the end of the world and I can use my other nibs but not a perfect fit for all Jowo nib units. I’m glad that the Gravitas nib is nice. Also note that I think the converter nipple is a hair thicker on the gravitas nib unit as the included converter is tight on that nib but loose on my Jowo nibs, so best to swap to a standard converter when swapping nibs, and vice versa if you put a gravitas nib in another pen, use the gravitas converter too, as my normal jowo nib converter is too tight.

Excellent customisation and personal service

Emy kindly fitted my initials to my new HomoSapiens Bronze Age. Matched the trim colour perfectly. Looks great. Emy’s personal attention to my emails and request etc were fabulous. I can highly recommend Pen Venture.
