The Pilot Falcon (previously known as the Namiki Falcon) is an iconic pen in the fountain pen world. It is most famous for its rhodium-plated 14k gold soft nib, which provides line variation when you change your writing pressure. This solid black fountain pen has rhodium trim and includes a Con-40 converter packaged in a Pilot gift box.
The softness of the nib is such that if you want to use it for daily writing you can, without having to flex it out. Though if you do want to showcase line variation, all you need to do is increase your writing pressure on the downstrokes and it's there for when you need it. Pilot doesn't advertise this as a "flex" pen, though it has that reputation in the fountain pen community. It most certainly provides distinct line variation, though you can overdo it, so just be cognizant of how far you're pushing it when you flex the nib tines.
The soft extra-fine nib is quite fine, and has a very toothy feel to it though it does provide the most dramatic line variation of all the nib options. Pilot (and other Japanese nib companies) has a reputation for grinding their nibs finer than European brands. We've found that to be the case with the extra-fine and fine nibs, while the medium and broad nibs are more similar to European nibs.
The threads on the grip are subtle, and while your fingers may touch them while you're writing, it's not bothersome at all for most writers. This is a slightly lighter pen than most at 19g, a noticeable difference from the heavier Pilot Metal Falcon. It's well-balanced with the cap posted or not. The screw-cap pushes on the back of the pen to post, and holds very firmly.
While the Falcon is certainly an investment, if you appreciate Pilot's quality and are looking for a reliable soft nib in a professional-looking pen, then you should give this pen a serious look.
