TWSBI 580/540 Comparison



Ever since TWSBI announced that they were replacing their flagship pen, the Diamond 540, with the Diamond 580, everyone has been curious what would actually differentiate the two. If you remember, a couple of years ago the Diamond 540 replaced TWSBI's original pen, the Diamond 530. With that upgrade there were some subtle differences, but there was an increase in ink capacity. Well, there's nothing that drastic with the changes to the 580, but even still, it's worth pointing out the differences.

There honestly aren't any drastic changes from the 540 to the 580. TWSBI has been updating periodically on their Facebook page,  so nothing I'm talking about here should be a huge surprise. FPGeeks also did a blog post that has a pretty good pictorial of the differences. Bottom line, if you liked the 540, you'll also like the 580. The changes were mainly for manufacturing and quality/durability reasons.

The one thing I know I'll get asked about a lot that I don't cover in this video is how the nibs perform. The 540 started with Schmidt nibs, then moved to Bock, then Jowo, so it was a little tough to nail down exactly which nib you'd be getting when you bought one. But the 580's will all be coming with Jowo from their release. I'm told by TWSBI that there shouldn't be any noticeable difference with these nibs over previous ones, and I'll test that for myself in a couple of weeks when I have the nib units in stock to be able to write test. But the cool thing is that all of the 530, 540, and 580 nib units are interchangeable, so you can use older nibs on your new 580, or get 580 nibs for your older TWSBI pen.

    Hi, thanks for this instructive video. I believed the notches in the nib collar were designed to avoid the
    section to rotate. From your video there is nothing which prevent the
    plastic section to rotate. How secure is the section kept in place?

  2. Hi Brian, thanks for the comparison. I am one of the people that had the filler cap crack so I am glad to see that metal ring there. The crack was my fault because I put the plunger assembly in wrong and then tried to tighten the cap to correct for it. So I don't blame TWSBI but I'm glad they are protecting the 580 from people like me. :)

  3. Thanks for this!


    I actually find the design changes unsurprising. I have a dead 540 that I'm attempting to repair, and the places where the barrel cracked (and where ink is mysteriously trapped) are exactly the places where TSWBI redesigned the pen body. Seems unlikely to be a coininkydink.
