Just had an idea: "What about adding a movement limiter onto a flexible nib, to prevent overbending?"  -_-

 

There is already something like that. The Pilot Justus 95 Fountain Pen has a user adjustable overlay that not only affects the flexibility of the nib, it limits how much the nib can flex. Have a look at the pen here:

By the way, ignore the price on of the Pilot Justus 95 pen at the link above. That seller is in the U.S. where Pilot fountain pens cost about double the price you can find if you buy direct from a reseller in Japan.

Ok, I can see what they have done.  -_-

 

HOWEVER!!!  the way I see it:  the flexibility of a nib is determined by the movement of the tines.  As one applies pressure, the tines move up and out (which widens the line until the meniscus breaks).  

 

I never get it right, is it break or brake?  By the way, have a look at Nibs Mechanics    ;) 

 

They adjust the flexibility... I want to limit the movement to prevent damage.  Their adjustor sits directly on top of the nib... I thought of having a distance between the limiter and the nib, so the character of the nib is not altered.  a bit like trainer wheels.  :D

Swapping nibs, exchanging nibs often, daily, has turned up as a topic or point of comment several times.  In my opinion, fountain pens are not designed for that.  Sure, nibs CAN be exchanged, a twice, three times to get it right, and if the nib ever gets damaged.  Finito.  For detailed information click here to get to the article on my site.
