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 clear demonstrator 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!

Stinks, creeps, plastic is fragile, nib too stiff

I gave this pen 2 stars because I do like how thoroughly it comes apart and cleans easily. The design feels smooth in my hand. The feed is wet and kept up well.

That said, I'm pretty disappointed in the pen. I do not recommend it. Here's my gripes:

1. The smell. IT IS BAD. And it does NOT go away. Folks who say it does are getting used to it, IMO, and/or keeping it somewhere with lots of airflow. The smell is a result of ongoing degrading of the plastic. You can wash it with soap to get rid of it for a day, but it will come back. If you are a person who likes "stinky" cheese, though, you might not mind it... some people do seem to perceive scents differently.

2. Nib creep. And feed creep. And creep from the feed into the barrel, and then along the threads and onto the section. Everything is so wet and loosely fitted together, and the ink is like a zombie horde at the windows, just waiting for an opportunity to break out. I constantly have ink all over my hands. I tried using oil to prevent it, and that helped, but I have not yet been able to stop it without greasing up my whole pen with lithium. Which I guess I'll try next. Of course, that's assuming I can even still use the pen, because...

3. The plastic is too brittle. Sick of ink creeping out of the reservoir and into the barrel, and seeing it had a rubber O ring that was supposed to stop that, I thought maybe if I tightened it a little more than I had been, it would compress the O ring and actually seal. So--as a woman who is not particularly strong, and using my fingertips--I applied a little more torque, and POP! I cracked the cylinder. Currently, the pen is held together with literal Scotch tape.

4. The nib is too stiff. The whole reason I GOT the pen was for flex. But this flex is not usable as-is. Applying enough pressure to make the tines flex at all (and I do mean AT ALL, I'm not asking for much here) gouges and bruises the paper so badly, it instantly bleeds through. It also makes the paper absorb the ink along those bruise lines, so if the ink isn't super dark, you'll see extra-dark railroads.

I've tried and tried to use it for flex, thinking surely it's me, surely it's just user error, surely I just need to fiddle with nib placement, but no. It is too stiff. I cannot use it for handwriting except as a regular fine nib pen. Attempting calligraphy with it produces shaky and unnatural writing because I'm using so much force.

I haven't tried modding the nib with a rotary tool yet. I will try that next. I figure, the pen is already broken, so there's not much left to lose. But frankly, even if modding it makes it perfect, I'm still annoyed. A product should not require using power tools to make it accomplish its most basic function.

Also, and maybe this one IS me, but... When I do spread the tines, and then let them spring back together, the line doesn't snap back to being narrow. It tapers off slowly over the course of half a letter. Which means, functionally speaking, using it as a flex pen just means extra-bold writing with occasional thin bits. I think the feed is maybe too wet? But attempting to tweak the flow doesn't fix this issue. I have no idea what's causing it. All I know is, other people's pens don't seem to do this.

I've been able to use the pen to ink outlines onto drawings. Strathmore drawing paper is thick and sturdy enough to withstand more pressure than writing paper, and I've been able to get a bit of line variation. And I'm the sort who likes to fiddle, so I've gotten enjoyment out of the fiddling, even if I haven't been able to get it to work.

But I still wish I hadn't bought a pen that stunk up my entire pen box.

Looks nice, smells bad, feels cheap

Good pen.

I like the pen, which is a great way to start with flex nibs while leaving your bank account intact. The steel nib seems tougher on the osteoarthritis at the base of my thumb than a gold nib.

My first flex fountain pen.

Bought with a doubt that I would like it, but so far it worked amazing! For it's price and functionality - great money investment. Writes smoothly, really to achive line variation, good as writing tool and a sketching tool too! Love it, and didn't had any problems with it.

Awful "Flex" Fountain Pen

While the fountain pen writes decently, the main reason I purchased this was the flex nib itself. I won't sugarcoat it, it's awful. You have to really put in a lot of pressure to get a different line variation every time you write, which is tiring.

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.
