Photo taken from Japanese blog: Originally a sealed streamlined cap, the modern pen cap has a small hole at the top to meet safety standards, helping to prevent suffocation if children suck it into the throat. This part is the small, circular black component at the bottom of the photo.
The pen measures 5. The line is incredible smooth regardless of the angle. So what is it like to actually write with a fresh, new Trident. It showed me enough structure that I was able to work out how to disassemble the Trident.
Hornbeck web forum pseudonym contacted me, asking for some advice on how to disassemble a Sailor Trident pen. Also, there are no oily blobs. China, which currently produces about 80 percent of the world's ballpoint pens, relied up to on imported ballpoint tips and metal alloys.
Let's face it, a disposable ballpoint pen is still more convenient than an expensive fountain pen that needs filling and periodic maintenance.
Loud's pen had a small rotating steel ball, held in place by a socket. Undaunted, he continued to search the web until he found a photo of a dissassembled Trident pen on this web site which had in turn copied the photo from this Japanese blog which has even more photos.
With no commercial viability, its potential went unexploited  and the patent eventually lapsed. Perhaps soft nib pliers would do the trick, here. If the socket was too loose, or the ink too thin, the pen would leak or the ink would smear.
Photo taken from Japanese blog: The nib cannot be taken apart for a thorough cleaning. As Sailor did the research this new pen design concept, it came to their attention that this very nib had already been designed by a company called Spacer. Hornbeck kindly gave me permission to include that post here: Just as three legs are sufficient to make a table stand on its own, so Spacer discovered that three sets of tines would allow a pen to write at any rotation and angle.
I asked a Sailor representative about this and learned that this was an arbitrary naming of the pens to give them a modern image like a plane.
The three tined Trident nib was far more difficult and costly to produce than a traditional fountain pen nib. Eraser Mate Ballpoint Stick Erasable Pen Ink is pressurized, allowing you to write at any angle for complete versatility.
