The Noodler's Ahab flex pen features a steel flexible #6 nib and a slide piston mechanism. If you'd like, you can even remove the piston mechanism and use the pen as an eyedropper for a massive 6ml ink capacity. This solid black Ahab is made of a celluloid derivative and is technically biodegradable and formed from a "renewable resource". The vegetal resin body of this pen may show particles or striations within the material. This is most noticeable in demonstrators and bright colors.

The Noodler's flex pens were designed for the hands-on tinkerer - they are made to be taken apart and adjusted. The nib and feed pull right out and can be adjusted and heat set for optimal performance. Don't be afraid to get a little ink on your fingers while you learn how to use this pen.

As a simple rule of thumb for writing with a flex pen, just apply slight pressure on your downstrokes, which will spread the tines and increase the line width, achieving that optimal line variation. Make sure to go slowly so that the ink can keep up with your writing. As with any flex pen, it just takes practice!

Due to the residual machining oils used when cutting the feeds for these pens, we highly encourage you to give the pen a good flush before use. We recommend any of the following options: distilled water, water with a touch of dish soap, a pre-packaged pen flush, or a solution of 10% clear ammonia to water. This should resolve most ink flow issues!

Great for large arthritic hands

Easy to grasp and manipulate. Smooth ink flow. Has enough weight to feel it in your hand, but not too heavy.

A Tinkerers Pen

I watched quite a few videos regarding this pen before I made my purchase, so I was not disturbed by needing to tweak it a bit. First and foremost this pen really does need to be cleaned thoroughly. I followed some old Goulet video recommendations for adjusting and heat setting and I'm very pleased with this pen now. I don't get the wide sweeping flex widths I saw on the videos. That's ok with me because my handwriting is by most people's standards quite small, and I get enough flex to suite my taste. All in all I've learned a lot and I'm happy with my purchase.

Not a good pen

I would not purchase this pen again. The piston filler is not smooth and when I'm trying to fill it I often end up with ink everywhere; the internal works of the pen often become clogged up with ink where ink shouldn't go and I have to clean it out with a syringe and water; the seal of the pen is bad so that even a full piston of ink dries up within a couple of weeks even if the pen is capped tightly; and of course the infamous stench takes over a year to dissipate. The flex of the nib is fine but absolutely not worth the enormous trouble of using the pen. I have much cheaper pens that work much better.

Love using the pen. The only minor issue I have is that I didn't realise that one had to unscrew the cap.

Heed the reviews�this is a bad pen

I received this pen as a gift and was excited to try the flex nib. Unfortunately, I experienced the same issues with this pen recounted in many of the reviews. 1) It leaks ink all over my fingers literally every time I use it, and no matter how thoroughly I think I've cleaned it out. Trying to achieve any line variation results in fat droplets of ink spilling all over your page.2) It smells awful. Like really awful, and I've had it for months now�the smell has not gone away or even abated. It smells like being in the home of a very sick person who maybe hasn't felt up to cleaning in a month or three. 3) It looks and feels cheap. A Pilot Metropolitan is cheaper and feels much higher quality. Taken together, all these flaws make the pen very unpleasant to use. And for a $25 pen they are truly baffling. My Pilot Preppys are infinitely preferable to this pen. Heck, I'd reach for a $0.10 Bic ballpoint before this pen.

Leaks

I want to like this pen, and I do like the way the flexible nib writes, though I expected more variance in line width with less pressure than it has. Unfortunately, it leaks so badly that using it requires a tissue to sop up the ink as it oozes out of the nib. The inside of the pen cap is always wet with ink, and my hands are always covered with ink when I'm done writing. It's also lightweight soft plastic, which to me feels cheap. It's inexpensive, but I have less expensive pens with none of these issues. I'm looking again for a flexible nib pen to replace this.

AHAB, replacing most of my pens

The AHAB is an amazing fountain pen especially when using the cartridges (purchased separately) The pen writes and draws perfectly. Takes a little practice getting acclimated to the flex nib but the learning curve is short. It is smmoth writes smoothly. Disassembles easily and is extremely user friendly. I plan to purchase a couple more. Loved watching the video with Brian and the Noodler founder.

Pretty good, although I don't have much experience with different inks

This pen writes amazingly. Unfortunately, the ink I bought with it(54th Massachusetts) is super wet, with an already wet pen. It does look super nice on really good paper, but unfortunately I haven't gotten to try different inks. It occasionally railroads, but that's usually when I'm low on ink. This was my second fountain pen( not a great choice, I know) after a Pilot Metropolitan. It's definitely not a bad pen, I just wish I had gotten something else, as this pen definitely takes a lot of tinkering. You will definitely get ink on your hands with this pen.

A Pleasingly Customizable Pen with the Classic 'Noodler's Smell'

I got three Ahab pens to use as a set: Black, Creaper Cobalt Blue, and Burmese Ruby Red filled with Noodler's Black, Baystate Blue, and Empire Red respectively. I replaced the stock nibs with Goulet extra-fine nibs and tweaked each pen to taste, first heat-setting the ebonite feed and then gently smoothing the nib with micromesh and Mylar. Getting each pen 'just right' was a unique adventure: for the first pen, the heat-setting was perfect on the first go. It took four or five attempts on one of the other pens, and two or three on the other. Each pen/nib had a different amount of smoothness before I polished the nib. All in all, it was a pleasant little adventure and I am happy with the results. The blue pen seems to write a bit wetter than the other two; I haven't tried swapping inks to test whether that's a property of the Baystate Blue, or of the pen itself. I like to tighten the caps quite firmly (thinking it might cut down on evaporation). As a consequence, I have to grip the cap tightly on either side of the pocket clip to open the pen without torquing the clip. In daily use, the pens don't require much attention, except for this: the blue pen seems to dry out overnight, just enough that it doesn't want to start; running tap water over the nib and feed for a second or two in the morning clears that up. Of course that makes the first sentence or three look a paler than usual. The other two pens require the same treatment occasionally, maybe a few times per week in daily use. The black pen requires it less often, perhaps because its (opaque) cap has some kind of liner material not present in the other two pens (which are translucent demonstrators). That said, they are dependable writers and I enjoy using them. I think every Ahab pen has its own unique 'personality' even after customizing it for a pleasing 'custom fit'. I wish they were all equally resistant to drying out; I suspect that is more a function of the pen than of the ink it contains. I like the unique piston filler design and the charmingly 'whale shaped' pocket clips. I even like the infamous 'Noodler's Smell' because, odd though it be, it holds pleasant childhood associations as it smells like my grandmother's sewing room. No telling what she kept in there, maybe something made out of the same plastic Noodler's uses.

Awesome Flex nib

you couldn't expect more from a pen at this price, 10/10. I recommend getting the noodlers art nib pack as well, only $6 more.

Sorry to say that they don't work

Unfortunately neither of the two black Noodler Ahab flex pens I bought work. I have gone through quite a lot of ink trying to get them to work, as has a friend who has two of the same pens (his work perfectly) without success. The ink just does not flow, it blobs hugely no matter what we do to adjust the nibs. I like how the pens are made in an environmentally friendly manner (however do find the smell of the plastic somewhat unpleasant, hopefully it fades over time), and the packaging and online service was exceptional. It's obviously disappointing that I am unable to use them, but, for the price it is no big deal.

Great pen for beginner!

I just got into calligraphy and this was my second pen, first one with a flex nib. The nib flexes fairly well, railroads a bit but that just may be me. Writes very smoothly, overall a great pen

Awesome pen

I bought this pen a month ago and I really like it. I have two other noodler's and I love the brand, I love that I can adjust them and take them apart. I would recommend this pen to anyone. Very good pen at a very good price.

Not perfect, but would be a good deal if it wasn't for the smell.

The pen itself feels rather light, but works quite well. However, the biggest problem with it is that the ben itself emits a very strong smell. Even after washing it thoroughly using a string cleaning product, it still smells. For the reason I believe the smell itself comes from the plastic. If this is a limited problem that only affects my pen, then I would recommend it.

Just completed my first drawing with this pen. The ink flows well and it is great for getting all the values I wish with simple changes in angle, orientation and pressure.Dave

Pretty much MEH

For me, too large of a grip. Also, I ALWAYS end up somehow with ink, a considerable amount, on my second finger. Never fails, happens every time I use it. The double tube chambers (forget what they are actually called) I could pretty much never get to work. The second little narrow one was a dog to fill. And here's the bad part, if you did get the darn thing to fill and then at some point you want to switch ink, well have fun cleaning this pen. You'll be spending more than a little time around running water. OK, I've been sort of harsh. Good thing is the nibs are nice and smooth.

A real double edge sword

Let me start by saying when this pen is working as it should, it writes beautifully. When I first got it and didn't understand the many quirks of this pen, I quickly wrote a negative review with little experience or time to base it upon. This pen has issues you must understand before using. It is not simply a pen you ink up and use freely. This pen is all plastic and the build quality is sub-par. The plastic has a nasty smell and the fittings are not super tight. Be prepared for a messy experience. Because of its loose fit and cheap parts, the ink inside will dry extremely fast. You MUST wash this pen frequently (after every use essentially!) if you want it to last. The small tube on the back of the feed can get clogged and ruined quite easily. The nib and feed have a tricky fit when put back into the pen so spend some time perfecting the fit because you will be doing it often. If you don't mind inky fingers and a lot of cleaning, this is definitely a pen you may enjoy. One thing I can't complain about is the price. You certainly wont find a flex pen for much cheaper than this one. If you plan on getting one of these, be prepared and understand the issues that come with this pen.

Great pen for the price

The Ahab pens are my go-to for everyday writing. They are economical, look great for the price, and come in a variety of fun color options. The flow is adjustable, so you can have a wet or a dry writer to suit your tastes, and you can even experiment with a little flex. If it weren't for the Ahabs, I probably wouldn't have gotten hooked on the wonderful world of fountain pens. Great product!

Nice to experiment things

Works with zebra-g, but a little too plastic for me, i would have prefered a heavy pen, but for the price it does what it is designed t : experiment (if you too, think about getting some more ebonit feed)Didn't use the nib delivered whith the pen so i cannot tell more about.Nicely packaged.

Great pen

The pen has a good size and impresses with vintage look and NIB that has no vent hole. To pick up the pen touch is soft, different from other pens, and despite the size it is very light and balanced. I love also the filling system that is simple matter and effective and has a good capacity. It can be used both for normal script, such flexing over pressure.Overall I enjoyed the pen that has a lot to offer despite the low cost ($ 20.00), so that for now will be my pen for daily use.A caneta tem um bom tamanho e impressiona pelo visual vintage e pela pena que n�o possui furo de respiro.Ao pegar a caneta o tato � suave, diferente das canetas comuns e apesar do tamanho ela � muito leve e equilibrada.Gosto muito tambem do sistema de enchimento que � simpres e eficaz e tem uma boa capacidade.Ela pode ser usada tanto para escrita normal, e funciona bem flexionando a pena com mais press�o.De modo geral gostei muito da caneta que tem muito a oferecer apesar do baixo custo (US$20,00), tanto que por enquanto ser� a minha caneta de uso di�rio.

Ink flow is weird

The Noodler's Ahab Flex has it's ups and downs. I can refill it, and ink won't run. It is strange. Sometimes it will write fabulously.

Frequently Asked Questions

How do I fill a fountain pen with ink? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It depends on the pen's filling mechanism, which you can find in the Technical Specs section above. 

Here's a quick definition of the most common filling mechanisms:

  • Cartridge - A small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write! Check out our quick guide here.
  • Converter - A detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter. Here's a video for how to fill a cartridge/converter pen using a LAMY pen as an example.
  • Eyedropper - A pen that utilizes the entire barrel as a reservoir for ink. Ink is directly filled into the barrel, allowing for a high ink capacity. Here's a video on how to do it!
  • Piston - A type of filling system that uses a retracting plunger inside a sealed tube to draw ink into a pen. They are typically either twist or push-operated. These pens cannot accept cartridges or a converter, and only fill from bottled ink.
  • Vacuum - A push-style piston that uses pressure to fill the large pen body with ink. They seal the ink chamber when closed, making it ideal for flying without risk of leaking. Check out our video on how to use a vac filler here.

Check out more info on these filling mechanisms including a video on how to fill each one on our blog.

How do I clean this fountain pen? 8EDA1617-F73A-4DAF-8245-6D2BF4ABEB7B

It mostly comes down to flushing out the pen with water, and sometimes a little bit of pen flush if the ink is really stuck. 

We put together a blog post with step-by-step instructions, or you can watch the video here:

We recommend a good cleaning every 2 weeks, and any time you change ink colors. Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.

For even more information about fountain pen cleaning, check out our Fountain Pen 101 video blog post.
