Noodler's Ahab Flex Fountain Pen - Black

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!

Rated 2 out of 5 by from I want to like the Ahab... I am enamored with flex nibs,so I was excited by the possibility of getting a flex nib at this price. The reality is Noodler's QC isn't very good. I have 6 of these pens from Goulet's and another vendor. Of the 6, 3 worked great with a little tweaking, mostly just washing out the feed with detergent and water, and adjusting the feed and nib relationship. Two of the six required major surgery on the feed and the remaining pen has an unrepairable feed (cut crooked at the factory) and a nib missing most of the tipping. It is now spare parts. Two of the six are very good pens and are at least as good as my wife's Esterbrook with a NOS 9048 nib.

Rated 3 out of 5 by from Mine works good as a dip pen Firstly, I did buy this pen knowing that you have to thoroughly clean it and tweak it before using. That being said, I'm having a heck of a time getting ink to flow out of the piston and into the nib correctly, with the nib sometimes drying up, and other times large air bubbles suddenly exchanging and large blobs of ink dropping onto my page. I suppose I could continue tweaking, but I've put in 3-4 hours so far and still am having no luck. For now, I've been treating it more like a dip pen, and having a lot of fun with the flex nib as a result, but this is not something I plan on carrying around with me as I had hoped.

Rated 4 out of 5 by from Great for a $20 flex My first flex fountain. Not as nice for Copperplate as a real calligraphy dip nib, but I also use this as a daily writer int he office. Ink can be a little trouble starting, and can drop off on fast, bold lines, but overall quite nice for a bargain pen. The plastic DOES smell.. quite badly actually. It's a combination of feces and stale chocolate. It will go away, but if you must repeatedly wash all of the black body sections and leave them to air out for a number of days, preferably with a fan in front. My hands smell like the pen when I screw off the barrel. Still, buy the pen. It's a good starter pen for anyone not looking for a wet noodle.

Rated 4 out of 5 by from Ahab flex Hi I recently received a Ahab flex. Very nice quality for the price. I have gotten several pages writing in and the pen nib has gotten much smoother. At first the nib was very scratchy and draggy. The nib definitely needs break in. As received the nib dried out quickly and would need a touch in a wet spot to start flowing again. I adjusted the feed out closer to the tip. The nib still drys and needs a slow first stroke to start flowing again. Compared to my Diplomat the Ahab Flex is a much different pen requiring a different technique and more pressure on the nib. My use of the pen requires me to slow down, but this slowness has improved my poor writing so this is not a gripe.

Rated 3 out of 5 by from great for desk, not for on the go I've been using some Noodler's pens for a while now. I've been using three Ahabs and two Konrads. All pens had good ink flow right out of the box. No big difference after washing the feeders with a mild detergent against cutting oils. I like the general feel, the nibs which are smooth and flexible of course. It seems to me, though, that they are more drawing and desk pens than daily pocket writers. When I carry any of them, except one of the Konrads, with me on the go, it is only a matter of time before they start leaking in the cap, or when writing a sudden gush of ink would appear under the nib ... I heat set feeds to be perfectly aligned under the nib, blocked the Konrad central breathing hole - like in the Noodler's tutorial on the subject - and nothing seems to help. I wonder about other user experiences?

Rated 4 out of 5 by from Aheb Flex Nib Pens. An ideal pen for writing shorthand (characters require thick and thin strokes). Better than good, being conservative) Sorry for late reply, but could not speak more highly of your service and delivery of pens. Time from order to Sydney delivery, was shortest possible and packaging excellent. I found your companys web page through a Pitmans shorthand site. As a young Police Cadet 46years ago, I had to learn shorthand and typing,(pre recorders etc), after a 45 year career I have recently retired, and even though I have used part shorthand, I decided to learn it properly again, to challenge the brain, like a foreign language. These pens were suggested at this site and I could not commend them highly enough for shorthand writing, or for any writing etc for that matter. I have a number of older fountain pens from my shorthand days and I have found your Web page to be one of the best I have used. (See next review space)

Rated 3 out of 5 by from Ink Supply I have used the pen for drawing and like the way it functions and makes marks. I do have an ongoing problem regulating the ink supply. The pen is prone to the nib drying up although the ink reservoir is filled. This problem is accentuated when using the nib for broader strokes. I have looked at the video on adjusting ink flow and the nib but an finding it difficult to obtain a satisfactory adjustment. Chris

Rated 5 out of 5 by from My most used pen, regardless of price I've been using the Ahabs (King Philip purple and Arizona) for over a year now. It's the best pen for the price. I thought I would never say that about anything other than a Lamy Safari/Vista. As I love to adjust my pens for my own writing style and needs, Ahab's are perfect. Everything can be manipulated/tweaked for your own requirements. My collection includes pens from 3 bucks to $400, and I pick the Ahab up most of the time. The nib was easy to smooth when I first bought it and remains flexible and buttery after many many hours of writing. The resin is just sticky enough to hold lightly and not have the pen fall out of your hand. I does stink for while when new, but the smell diminishes over time.
