Noodler's Ahab Flex Fountain Pen - Jade

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 - Jade is rated 4.0571 out of 5 by 35.
Rated 5 out of 5 by from Amazing, if a tiny bit finicky. I am extremely happy with this pen. This is a real true flex pen, that flexes nicely and holds a lot of ink. Also, unlike the original Noodler's pen, this one actually looks nice like my fancier pens. It does take some time to get it really writing nicely, I've adjusted it maybe 10 times and now it is writing really great. Tested with Noodler's BSER and it is really beautiful shading wise. Now I have heart of darkness in it, and the line variation still looks great. My only (very tiny) complaint is that the unflexed tip isn't quite fine enough for really nice spencerian, but you can't have it all...

Rated 5 out of 5 by from $20 pen writes like my $150 one Ok, so for real...I spent $20 for a Noodler's Ahab Flex Nib pen, and recently my wife's parents gave me a LAMY Accent fountain pen for my birthday. Don't get me wrong, the LAMY is a fine, fine pen, especially with a gold nib. But I'm hoping they never see this review, cause, um.... I actually think my $20 Noodler's pen writes even better. EEGAD! I said it. Yikes! So... this Ahab is an awesome pen. I plan on giving both the Ahab as well as the Noodler's flex pens as a gifts this year. I can't help it. They are great products, ugh, damn I feel like a frick'n commercial. Chris

Rated 5 out of 5 by from Can't beat it. First off, I'll never buy any pen-related item from another vendor. This company is about as reliable and as caring as you'll find. Second, thus pen is breathtaking. For 20 bucks, you just can't beat it. It has the potential to create beautiful letters and works of art. The cleaning is creatively simple. Be absolutely certain to flush it with the solution they recommend. It helps greatly. Another use I didn't expect was everyday note-taking. This thing can produce relatively thin lines when writing normally. Not once have I had mine skip. I think the key is finding the perfect nib/feed relationship and leaving it be. If this pen is even on your wish list radar, don't hesitate to buy it from the Goulets.

Rated 5 out of 5 by from Amazing first pen This is the first fountain pen I have ever used and it feels amazing. After opening the box I did notice the horrible smell which was easily removed after I washed it in cool soapy water. I don't know if I just got lucky with the nib but it glides over the cheap printing paper I use at work. By far the smothest pen I have used. Filling the pen was easy, just dip the pen and pull the plunger, I was able to write with it right away had no problem with the ink, I got the Ink Sample Package - Blacks, Waterproof. It is a bit noisy but I kinda like the sound.

Rated 5 out of 5 by from I love my pens!! This is my first fountain pen and I love it. I does take some tinkering but once you get the ink flowing it writes great. I had to get my first one replaced due to a chipped feed and then I bought a second one with the same thing and a scratched cap but the service here is wonderful. They sent me a replacement the next day for the first one and the second one they gave me a store credit and I bought a Konrad. The service is wonderful and so are the pens!!

Rated 4 out of 5 by from A bit of flexibility, for not much money I find the Ahab to be better than the standard Noodler's flex. Might just be because my hand is more comfortable with the larger pen but it seems easier to vary the line width. One problem I do have, however, is that in addition to line width variation, the Ahab produces thicker/thinner layers of ink. As Noodler's Black is so dependent upon ink/paper connection for its 'waterproof' characteristics, the Ahab is pretty much useless to me when doing pen/watercolor sketches. No fault of the pen but a problem nevertheless.

Rated 4 out of 5 by from Continued. I have picked up some valuable techniques from you articles and look forward to reading your newsletters and blog. Your videos are very informative and I commend you on explaining things in a simple way, that even I can follow. I wish you all the best and looking forward to a continued association and future purchases. Warren Chambers. p.s. (Handwritten note from you with the purchase was most appreciated). Comment on our society. Survey of Aust. High School students (your College equiv.) found that a lot could not read or write running writing, and this is before Ipads etc.

Rated 5 out of 5 by from Fave so far Maybe there are better flex nib pens out there, but I don't know about them, and they are not going to be so affordable. Writes fast without no problem, and slower fancier stuff, ie thick and thin without too much ink. I like being able to take the thing apart with ease. And Goulet's was ace to deal with. I'm in the UK and it was maybe 10 days to get here, max.
