The Noodler's Ahab flex pen 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. This clear demonstrator 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 colours.
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!
The Ahab Flex is the king of Noodler’s fountain pen lineup, being the largest-bodied pen. The Ahab features a removable piston converter and a large flex nib. But the best part about the Ahab is that it can be completely disassembled for cleaning or repairs, and the piston converter can be replaced with a large refillable cartridge or used as an enormous eyedropper pen
