Noodler's Ahab Flex Fountain Pen - Navajo

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 - Navajo is rated 3.9 out of 5 by 20.
Rated 4 out of 5 by from ahab good first fountain pen I've used dip nibs exclusively before buying this. It has impressed me, for 20$ you get pretty decent quality. I like how much ink it can hold, and I've always been a tinkerer, so I like that I can take it all apart and adjust as needed. The only problem was with the color of the Navajo. In the pictures it looks like a beautiful vibrant teal color mixed with a bit of reddish brown, assuming taking the color inspiration from the Navajo people's landscape and clothing. But in reality the blue is a bit darker with black and silver streaks. Not really the same, but not ugly. Just not what I really wanted. I think with these marbled design pens they should show a few different pens in the photos, to show how much the color/pattern can vary so you more accurately know what you're getting. Still a decent writing pen. Railroads occasionally for me, but not too bad.

Rated 5 out of 5 by from Noodler's quality control is better than before I have bought several Noodler's pens, and this one performed the best, indicating that the quality control at Noodler's is improving. I flushed the pen with water and a drop of detergent. That's all. When the pen was filled for the first time, the pen performed as well as any other pen, including more expensive pens. The Ahab is a comfortable pen to hold. This photos of this particular pen do not convey the color well, as pointed out by others. The photos show a lighter, turquoise pen, but the one that came was darker; however, the color was better than expected, too.

Rated 5 out of 5 by from Easiest Filling Mechanism! First of all, this pen is beautiful to look at. The color (Navajo) is a little darker than it appears in the picture on the website, but there is a lot of character in it. I absolutely love it. It also feels great in hand. I generally prefer a thinner pen and a triangle grip, but the taper of the grip on the Ahab is comfortable, even to me and my impacted wrist. It is light weight for its size, and nicely balanced. I can see myself doing a great deal of writing with it in the future. The flex nib is still something I need to get used to. It seems to take heavy pressure to flex out, but this is my first nib of this type, and I'm still getting to know it. I fully flushed it before using, and have had no problems with skipping or railroading. I was even able to get extremely fine lines by using no more pressure than the weight of the pen on the paper. The ink did bleed through when making heavier lines, but that is to be expected. I chose the Ahab over the thinner Noodler's Nib Creeper because of the filling mechanism. I am used to a piston-style converter, and was intrigued by the Ahab's slide piston. It took me a couple of attempts, but I managed to get the best fill I've ever gotten in a fountain pen. I expect that I'll look for other pens with this feature in the future.

Rated 3 out of 5 by from good flex pen I was torn about what rating to give this pen. On the one hand, it flexes very well and shows off my J Herbin emerald of chivor ink well. The flex is useful in practicing my calligraphy when I don't have a dip pen or when I don't feel like getting an ink bottle out.. On the other hand, I don't think the pen is attractive in real life as it is in pictures. My main issue with the pen is that it is so lightweight. I Iike a pen with a bit of heft to it (nothing major, but something like the lamy al-star) and this pen is just too light for me. I should have checked out the details on the pen before I bought it, but this pen just looked heavy. The feature I dislike may be one that others love.

Rated 3 out of 5 by from Not larger that Konrad, wobbly poster. The pitch for the Ahab says it the largest of the Noodlers pens. This is true in terms of certain body and cap diameters, but the diameter of the grip. The Konrad is longer in terms of cap, body, and overall length according to posted specs. The posted Ahab is longer but posting doesn't work very well. Unless one really forces the cap onto the body, the cap wobbles and tends to fall off. Without the cap, its too short for my hand that I consider medium size. I am experimenting with the flex pens and I've discovered I like the feel of Konrad acrylic over Ahab resin.

Rated 5 out of 5 by from Couldn't be happier! Specifically to the Navajo: I was intrigued by the color swirls of this pen from the Goulet pictures. Once the pen arrived I was pleased to see the colors up close. There are a few different colors appearing from a deep turquoise, black, grey, silver, and a hint of brown. I think I might color match with: de Atramentis Pigeon Blue, Iroshizuku Ku Jaku, Montblanc Meisterstuck "Permanent Grey," but for now I contrasted with de Atramentis Red Roses. The pen wrote flawlessly from the box without flushing or adjusting the ebonite feed. Ahab in general: I own several Ahab's now and I can say that I have seen a marked improvement from the pens I bought nearly two years ago. The last three Ahabs I purchased from Goulet have been superb from the box. I don't know if Noodlers has stepped up their quality control or if its a design change. But whatever it is, it had me at hello. I only mention a design change because my last three Ahabs seem to have a different shape at the nib section, where the nib and feed are inserted, from my previous pens. I am beyond pleased with Noodlers and the Goulet team. Thanks again!

Rated 1 out of 5 by from A Disappointment Unfortunately, I have to agree with a recent review of this pen in a different color. I found nothing to recommend the Ahab. The pen did not write, even after several flushings with water and then refilling and making sure the feed was loaded with ink. And, as pointed out by the earlier reviewer, the build feels flimsy, and the performance (lack of) does nothing to suggest the feeling is deceptive. Of course, there can always be one faulty manufacture of any pen, however well designed, but it appears a number of people have trouble with this model.

Rated 5 out of 5 by from Beautiful and Fun to Use This pen is fantastic. The color is great, and the size is perfect for me. I've had zero problems of any kind. Even without the flex nib it would be a great bargain. The flex nib definitely adds a bit of "character" to drawings and words, even without manipulating it deliberately. Goulet Pen is the best online vendor of any kind that I've ever dealt with.
