Nathan's at it again, creating another ground-breaking pen. He's made changes based on the feedback and insane demand for the Noodler's Nib Creaper Flex Nib Pens, and has developed one of the most interesting and ingeniously simple pens around today - the Ahab.
The Ahab pen is a completely different nib, feed, body, and filling mechanism than the standard-size Nib Creaper flex pen. It is still technically a 'piston filler', but it uses a push-type plunger instead of a screw-type.
Another great thing about this pen is that it's easy to take apart for cleaning and adjustment. The whole thing breaks down easily, no tools required.
Now even though this pen is a plunger-fill, you can fill it as an eyedropper by removing the whole plunger mechanism and filling the body (using silicone grease on the threads). I only did the test with water so far, but it held well and I was able to get close to 6ml of ink in this mammoth pen!
I thought it might be handy to showcase the difference between the Noodler's Ahab and the original Noodler's Nib Creaper Flex pens in terms of their writing use. My conclusion is that the nibs on both pens have about the same unflexed line width (somewhere around a fine), and they have around the same maximum line width, about 3mm when you really push it to the limits. But to me, the Ahab feels a little easier to flex. It's not an overly dramatic difference, just a slight improvement. I don't know if I can attribute it to the design of the nib itself, or just to the fact that the Ahab's larger size feels better in my hand and gives me more control over the pen. It's probably a combination of the two.
