We have recently learned that JoWo has a new style of their popular #6 nib. Fortunately, the old and new #6 nibs can be distinguished by the placement of the size marking (EF, F, M, B, etc.). The original JoWo #6 nib has the size mark centered below the area reserved for engraving or etching the pen makers logo in line with the slit and breather hole. The new style nib has the size marking on the right side of the nib. Here is a comparison photo of the new nibs versus the old ones. The top row has three of the new style nibs, the bottom has three of the old style nibs.

For our JoWo #6 products, the red ebonite products should not be used with the new style nibs, as the shoulder of the nib is wider and may cause the red ebonite housing to crack. The black ebonite products can be used with the new style nibs, but be aware that a heat set may be required, as the curvature of the tip of the new style nibs is slightly less than the old style and there may be a gap between the tip of the nib and the tip of the feed.

Since the acrylic feeds can’t be heat set, we don’t recommend using the new style nibs with those products.

We will be creating new housings and feeds for the new style nibs, though no schedule is yet known. We hope that the new products will be usable with both nib types, but we are uncertain if this is possible.

If you have any questions, please contact us and we will help you determine if you have the new or old style nibs.
