Noodler's Ahab Flex Fountain Pen - Apache Tortoise

The Ahab flex pen was introduced in late 2011 and is currently Noodler's most popular fountain pen. It 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. The 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!

Noodler's Ahab Flex Fountain Pen - Apache Tortoise is rated 4.3448 out of 5 by 29.
Rated 5 out of 5 by from Worth tinkering: don't pitch it! After contacting GPC and getting a specific tip on heat-setting, it took four tries at heat-setting the feed to use this pen for writing. Ten days ago was the fourth heat-set try and since then it has been writing very well, with good flow at light pressure and no scratching. My concern that the ebonite could 'revert' has been allayed. This pen has a lot going for it: a very satisfying pen to see, hold and use, the variegated pearlescent coloring of the Apache Tortoise is appealing and rich. The size and shape of the grip is exemplary. At the price, I could get more Ahabs in some of the other appealing 'tortoise' colors.

Rated 5 out of 5 by from Great American Small Business The Ahab pen is one the best deals in fountain pens ever. It performs like a pen ten times its cost. As far as your company: Superb company, superb service, and superb products. But what impresses me the most is the wealth of information that you have taken the time and trouble to put out in youtube for the benefit of those of us who love writing with fountain pens. My sincere compliments go to all in your company. Keep up the good work! P.S The care you put into packing the items is like no other I have ever seen.

Rated 4 out of 5 by from Second Ahab This is my second Ahab. Loved the first but this one is proving a lot harder to tune. It is a little more finicky about the inks it will work smoothly with. I tried the tuning tips from Goulet and Noodler's but it still seems to want to skip after just a small amount of writing. I've tried wetter inks and drier inks from Diamine and Noodler's but the problem still seems to persist. The first Ahab has performed flawlessly and really seems to like the Noodler's Nikita red ink. It may just be this one nib, two pens, two opposite experiences. But when it works it is a great writing instrument.

Rated 5 out of 5 by from Another great Ahab Of the 8 Ahabs I have purchased, tuned and mostly given away, there was only one dud - and that was a finish problem, not a functional one. This one, in 'Apache Tortoise" is phenomenal - the depth and variation of the semi-transparent striations and swirls is incredible, especially in this price class! Nib and feed worked great after an initial soapy flush, and i almost regretted having destined this pen to be united with a Goulet 1.1 mm cursive italic nib. Once that was installed, however, I was absolutely convinced: after heat-setting the feed to the nib, this combo writes along with the best of them, rather wet, and with impeccable line variation. Currently combined with Rohrer & Klingner's "Salix" ferrogallic ink, it amazes everybody who tries it. Fully recommended!

Rated 5 out of 5 by from Excellent Look and Value For Money The pen's body material, colour and finish are excellent considering the 20$ price tag. It smells nice (opposite to other comments about this). I would not recommend this pen if you like oversize pens since the barrel and the grip sections would be 'standard' for you(personal view only). I would definitely suggest swapping the standard nib with a Goulet one (a dual tone will look fantastic) if you are interested in standard writing. Outstanding packaging from the Goulet Despatch team (lolly included!)

Rated 5 out of 5 by from Yeah! More colors Ive gotten to the point where I kind of understand how to adjust Ahabs to work well for me. I love the variety of colors and Ahabs are very comfortable to hold. This is my fourth

Rated 4 out of 5 by from A great, beautiful pen, even when not flexing My first Noodler's flex pen, and it's a great performer and looks and feels high quality. Amazing buy for $20. The green tortoise pattern has depth and swirl, and is semi translucent so you could see ink levels through the swirl if using it as an eyedropper. I have to get the hang of flexing, and I understand it is stiff for a flex pen. I actually sprung the nib after trying to flex for the first time, and not while using excess force either. I was lucky to be able to flip it over and bend it back by pushing against the paper, not a recommended technique of course. But even if you forget about the flexing, that stock nib writes very smoothly as a regular fine nib. You can also switch the nib out with many other nibs if needed. The shape is ultra comfortable at the grip, and it is light and solid.

Rated 5 out of 5 by from My most beautiful Ahab With pens manufactured like these, the actual look of an individual item is always up to a lottery. In the case of my Apache Tortoise, I seem to have won in that lottery. Because it's astoundingly beautiful. The striations and colors are just right, and it looks very organic origin. I have other pens, a Konrad for instance, that don't look good and where the colors have come out all wrong. But my A.T. Ahab is perfect. Originally I fitted a Goulet Broad and had it for writing and such.When it finished its turn as a letter pen, I fitted a Goulet medium instead, for more utility. That also involved moving the feed a little deeper in relation to the nib, in order to adapt to the lower flow needs of the medium nib. Both setups were 100% successful. Keep the breather tube. It makes flow more consistent and even. The medium version served as my training pen (hand writing) for awhile. To date, it is one of my best writers ever. And I do have all the expensive classics in my collection too.
