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!

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.

Love using it with no cartridges or converter, huge amount of ink, love being able to see amount of ink left in the pen, love the flex nib, in short, there's nothing not to love about this fountain pen.

The nib was to far out letting to much ink come out. I pushed it in and it helped. I am also going to heat set it some time in the near future

Not a regular fountain pen….

This is not a fountain pen you just put ink into and start using. I will go through the steps to set up this pen.
1: Disassemble the pen. Be careful with the breather tube, you don’t want to lose that.
2: In a warm bowl of water put the feed and nib to soak. Get an old toothbrush, a good degreasing dish detergent like Dawn and get a brass shim to “floss” the nib. A .025 metal feeler gauge blade will work also.
3: Scrub the nib and feed thoroughly with the toothbrush using the soap and warm water. Scrub the shim or feeler gauge blade to remove oils then “floss” the nib while it’s in the bowl. The idea is to remove any and all oils from the manufacturing process.
4: Dry everything off and reassemble the pen. Push down the piston on the pump converter to make inserting the breather tube easier.
5: Make sure 8-10 ribs of the feed are exposed from the end of the grip section. Usually 9 ribs is about good place to start.
6: Once the nib and feed are seated correctly (there’s a notch the nib goes into). Fill the pen by submerging the nib & feed and a bit of the grip section into your ink. Pump the piston converter a couple of times till the converter is completely full.
7: Test the pen. If it writes too wet, push the feed in 1 rib. Test the pen. If it still writes too wet. Push the feed in another rib. You should find the sweet spot where the pen writes the way you like. If the pen initially writes too dry, pull the feed out one rib. Continue this procedure till you find your “sweet spot”.
The same steps work for every Noodler’s pen. Though the number of ribs showing might be different from model to model.
There is nothing wrong with Noodler’s pens. I use them for my artwork exclusively. I often carry a Nib Creeper as a vest pocket/shirt pocket pen. They are inexpensive, robust, pens that perform gloriously when tuned. They can be fitted with a multitude of nibs of different types. The bonus are the refillable .308 cartridges. They give the Ahab, Triple Tail and Neponset a huge ink capacity without resorting to eyedroppering the pen. So no ink burping from hand heat. I have 10 Ahab, 9 Konrad, 8 Nib Creeper and a Triple Tail. All of them have been tuned to perform as well or if not better than any TSWBI, Pilot, Kaweco, Platinum, Pen BBS, Jinhao, Asvine, etc… pen I own.

Excelente!!!

La verdad es que es dif�cil encontrar plumas con plumin Flex fabricadas al efecto y esta es una de ellas que cubre todas las expectativas a un precio muy asequible. Una maravilla

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.
