Noodler's Ahab Flex Fountain Pen - Iroquois

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 - Iroquois is rated 4.4 out of 5 by 10.
Rated 5 out of 5 by from Great 20 dollars spent! First off, I really was impressed with the color of this looks better in person. I love that you can take this pen apart completely to clean. This is my first "Noodlers" pen...I can say I'm very impressed. Construction is much better than I anticipated. I read a lot of reviews that said you may have to tinker with the nib/feed to get it to write well. I was ready to tinker away but it came out of the box writing fantastic. I really enjoy that I can use it to write normally and then flex away when I want to "try" writing with character. I highly suggest if you are on the fence about trying this it! Great Job Noodlers and Great Job Goulet for providing perfect service all around.

Rated 4 out of 5 by from Pen You won't find a better pen for the dollar. Not even close. However, this is a bit of a fiddlers pen if you want to get the best expressive performance out of it. It's easier to do that with this pen than any other, though. I do have trouble getting enough ink to flow for really wide lines. Pretty good instructions on how to affect that on this site and with the pen. Wish Noodler's would have mentioned the current pens have the square section wiper O-ring on the plunger and not the old round section one -- then I wouldn't have had to purchase the spares.

Rated 5 out of 5 by from Ahab Pens Have not inked this one yet as it is one mainly purchased to add to my Ahab collection. I am working on collecting all the different Ahab pens but I am sure that it will write as well as my Mandarin Yellow, Clear Demonstrator and Ahab's Pearl (White) which are my daily carriers and workhorse pens for all occasions and will be inked at some time in the future.

Rated 5 out of 5 by from Best bang for the buck, period. I experienced none of the problems I read about elsewhere. I broke it down and washed it thoroughly with no-suds ammonia & water, dried it, and re-assembled it, being sure to get the nib in the small recess cast into the section, and taking care to align the shoulders of the feed with the shoulders of the nib, and align the nib slit with the feed slot. Inked it up, and it was off to the races. I've never owned a more expressive pen of any kind. This thing writes from a fine hairline (literally, a hair's width) up to a thick stripe a full 3/32" across, without any hint of railroading. The nib was "uh-oh" stiff at first, but with about a week's use, has loosened up considerably. The quality, fit, and finish of this pen is far beyond what you'd expect from a $20 pen. The fill adapter worked perfectly, first time; no leakage whatsoever; feed is always there, always ready. I've never had to coax ink from it, even after sitting for a couple of days. I'm getting several!

Rated 5 out of 5 by from I just love this pen This is the sixth or seventh Ahab for me. I've given away a few and currently have four going. I use different colored inks and try to keep one around whether I'm at work or home. They write beautifully, but sketch even better. I'm happy to mess around with the feeds, so I've customized all mine to flow pretty strongly, even on absorbent, textured paper. The ink barrel is big, so they don't run out fast even from a lot of drawing. The real appeal, though is in the flexible nib. It can't be beaten for fast, expressive lines. I have every intention of getting more of the things.The price is great, too, since you can travel with them and take them sketching in easy-to-lose environments like marshes and rivers without worrying about having the thing go missing. They're great.

Rated 3 out of 5 by from Good pen for $20 I have tried it with Private Reserve Chocolat. Not my favorit ink although it writes good. The ink flow is god. The flex part might not be for me or maybe I have to practice more. The pen is fairly large and feels nice to hold. I have seen other complaining about some problems. My pen have not had any problems but one. It smells really horrible. I did wash it but it still smells. It is a good pen for $20. Buy one and try it. If you do not like it, give it to a not so close friend or enemy ;)

Rated 4 out of 5 by from Practically perfect in every way. I was asked for a review of this pen, and I'm happy to do just about anything for a company that serves me as well as Goulet does. The Ahab Iroquois is terrific. (I even like the smell!) I bought it in order to have a pen to fill with brown ink. That's why I also have an Ahab Comanche (for Antietam Red), an Ahab Arizona (for Apache Sunset, an orange-to-yellow ink for an orange-to-yellow pen), and an Ahab Green Mountain (for Green Marine ink). I love the weight of these pens, which is practically nothing, and think the converter is so cool that I just open the pen to look at it every now and then. The only reasons the pen didn't get five stars from me is that I wish the cap posted better and that I didn't find much flex in the nib. I always snip the ball off and grind a new nib to my preference, so I can't fault the Iroquois for not being ready for me "right out of the box."

Rated 3 out of 5 by from Could be better. The pen color is very beautiful! I still have problems to adjust the pen and the feeder. So far not got the balance between good flow and no leaking but I believe it is only a matter of time. The nib scratches a bit on paper but is not a serious problem.
