JoWo Flex Nib Units

These #6 JoWo flex nib units will fit several modern manufactured pens such as Edison, Penlux, and Franklin Christoph. Through years of research, trial and error, Richard Binder developed a method of transforming a modern 14K nib unit into a flex nib that closely emulates the flex nibs of old. Under Richard's tutelage, Linda has mastered this artisan modification and offers her version of this highly sought after nib. 

We are no longer able to get the feed and housing units that Bexley used. However, if you have a Bexley and want a 14K flex nib for it, we can do this on your housing unit. Please contact us for more details on this option for Bexley pens.

Please note that these nibs are serious flex nibs. If you are used to a Pilot/Namiki Falcon or Noodler's flex nib, the amount of pressure those nibs require will damage our flex nibs, possibly to the point of destruction. Damage due to overflexing is not covered by our warranty.

*Please allow an extra 10 business days for the creation of your flex nib

Because we want you to have the best experience possible when you purchase a fountain pen from us, we tune each nib at no extra charge unless otherwise requested.  Nibs are installed in a pen body, filled with Waterman Mysterious Blue ink, tested on better than average quality paper, then adjusted for alignment, ink flow, and smoothed to bring it to the standard that you should come to expect when buying a fountain pen or nib from Indy-Pen-Dance.

    I really love a good vintage-flex nib, so I'm comparing this nib to that on my 90 yr-old Waterman 52. I bought this nib in an EF.

    There are several things I like about vintage flex:

    1. A flex nib that flexes well with very small changes in writing pressure allows everyday writing with a nice flair. This nib is every bit as good as the W52 for this purpose, so I really love that. This is the majority of my use for these types of nibs.

    2. Smooth writing. Both the W52 and this nib are super smooth to the lightest touch with no skipping or hard starts. Because this one is an EF, it writes a significantly finer line with no pressure than the W52.

    3. Pushing the nib and getting a nice thick line. The W52 is better than this nib. At first, I had pretty serious railroading issues with this nib, but I quickly found that it's more sensitive to the ink than the W52 in this regard. After trying a bunch of inks, I have found that Noodler's 54th Mass allows this nib to really flex without railroading. I can get 1.8mm without railroading issues whereas the W52 will do about 2.2mm without issues. I'm guessing this nib could be improved with a better feed to nib interface. That might make it less ink sensitive too. In the end, the W52 will spring before it railroads with just about any ink, and that's not true of this nib/feed.

    4. Both the W52 and this nib are very soft and bouncy--which I really like.

    Additionally, this nib reverse-writes very smoothly with a razor-sharp fine line. The W52 nib will dry out in less than a week without use. I know the sealing system in the Edison will keep the ink wet without use.

    In all, I'm very happy with this nib, and it allows vintage-type writing with a modern pen and filling system (I really hate the old W52 lever bladder). I also love the keyhole on this nib!
