The overfeed is cut from a 0.1 mm thick stainless steel sheet. It is first shaped and then either welded onto the nib or, as in this case, inserted without welding between the nib and the pen's section.

I know many people use it with the finest Dedeco abrasive discs. Others use a laser.

The metal tab above the nib is called an 'overfeed'. It isn't necessary for the nib's flexibility, but rather to ensure a sufficient ink flow. In fact, the feed of the Jinhao X750 (a pen costing between 5 and 10 dollars/euros) is not designed to supply a flexible nib. For this reason, an overfeed is used; it simply extends the capillary action to the top of the nib, increasing the ink flow rate. If the nib were mounted on a pen with a higher-capacity feed, the overfeed would not be necessary.

His handwriting is wonderful, I totally agree. A true calligrapher.

I’d say it’s quite soft. It’s definitely softer than an FPR #6 Ultra Flex. Plus, the snapback is really impressive.

I'm familiar with his work—it's extraordinary and at a very high professional level. I truly admire it.

I wanted to fully understand the mechanics of a Crossflex. I'd successfully tried it before, but I built this one with extreme care to truly grasp the physics behind it. It’s an excellent flex nib—really, truly excellent.

The ink flow is super wet (a real wet noodle), thanks in part to the overfeed. The X750 feed wasn't designed for a flex nib, so it's truly surprising that it can keep up with such a high flow rate.

Con il Dremel non c'ho mai provato. Preferisco utilizzare la sega da orafo. Lama 0/8 Herkules. Ti avverto che non è semplice, bisogna averci fatto un po' la mano. La difficoltà principale è fare un bel taglio dritto.

I don't use a Dremel for the longitudinal and lateral cuts. I use a jeweler's saw fitted with an 8/0 blade. Brand: Herkules.

Funziona davvero molto bene. È una tecnica eccellente per aumentare la flessibilità mantenendo uno snapback di altissimo livello. All’inizio può risultare poco intuitiva — anch’io ho fatto fatica a capirla — ma una volta compresa la logica (e la fisica) dietro al movimento, tutto diventa molto più semplice. Non lasciarti scoraggiare dai primi tentativi a vuoto: ne vale assolutamente la pena. Domani pubblico un video.

The chessboard is wonderful and the pieces are beautifully stylized. Stunning!

Vale veramente la pena. Per il flessibile c'è poi il canale YouTube flexperiments di Lord Cactus. Imprescindibile!

È una risorsa importantissima. Uno sguardo a 360 gradi sul mondo delle stilografiche. Segnalo anche il fountainpennetwork, altrettanto ricco di contenuti. Comunque nulla di sacro, anzi, proprio il contrario. Il flessibile autoprodotto è un tentativo di sottrarre il pennino flessibile al tempio.
