It’s about 4.1" closed, but 5.25" posted. I find it to be very comfortable to write with.
For me the 0.5" works best because a lot of writing is done in pocket-sized notebooks where there’s an advantage to being able to cram more lines into a smaller space.
That led me to standardize on that refill, and basically only buy pens that can accept it. That way I have one little bin of refills, but I can use different pens depending on what I feel like. 
I very much find the Kaweco Sport comfortable to use, posted.
Do you use a plastic one or one of the fancy metal ones?
I used to have a brass one, but passed it on because I’ve discovered that brass and copper pens have an odor I dislike. I have 3 plastic Kaweco Sports, the first of which was purchased for paleography class some years ago, and two others I’ve purchased since.
Thanks. This is good to know. There’s a stationary shop I visit every once in awhile who carries a nice selection of Kawecos. I will definitely try them out next time I visit the shop. Thanks for the info and recommendation.
If I was using a pocket-sized notebook I’d definitely use a 0.5 also. Makes complete sense.
Always learning new things. I assume “posted” means fitted to the end of the pen?
I’m not much if a pen aficionado, more of a pen imposter, but I will happily and vainly boast that my favourite pen, prior to reading through this thread is/was the Uniball Jetstream 0.7 Black. I probably have a dozen or so lying around. But more importantly it was the favourite of The Pen Addict … so I feel validated! 
But now I have more investigating (and purchasing) to do it seems!
I love this thread! 
I listened to the show and immediately unsubscribed for reasons that I will keep to myself
Thanks for asking. I did. I purchased the Levenger Wineberry Circa Napa Sliver Foldover Notebook.
I appreciate everyone’s advice, thanks!
I bounce around between notebooks from time to time. Your post got me thinking more about Circa again, so I just switched back to it for my daily notebook, moving my hole punch to my office, etc. Yay!
Just doing some pen browsing and came across this new beauty, it’s only $7000+ 
We have expensive hobbies on this forum (It probably goes without saying but obviously I will not be buying this. My first thought when looking at the price was “that’s quite a few iPads”, and I’ve still not replaced my cracked iPad yet.)
I could buy two Vision Pros for that much!
While you could buy Vision Pros or iPads in multiples instead of this pen, consider 10 years from now. At that time you could likely sell the pen at a profit. The iPads and iVision: not so much.
Moleskine is not recommended for fountain pens. I had a Moleskine notebook that was perfect otherwise, but fountain pen bleeds through.
I was digital only for a while, but rediscovered the use cases for handwriting. Nowadays I use digital for anything I will want to search years in the future and handwriting for a daily journal, drawings, checklists or checktables that don’t need to be stored forever. Handwriting is part of how we learn.
Apart from all that, fountain pens and ink are a fascinating pursuit. After giving up any form of handwriting for several years and only ever using black ink before, I got back into it a few years ago (because of MacSparky and MPU) and discovered an entire universe of pens, nibs and inks.
And as unused. That pen looks as if it would be horrible to hold when writing.
Visconti specializes in high-end statement pens for collectors.
One of my favorites for long form writing is the Lamy 2000 fountain pen. It’s comfortable in hand, and has a large ink capacity. It lists for c. $280.00 US, but I bought mine for less than half that on sale.
Another is the Pilot Custom Heritage 74, which on sale is usually available for c. U.S. $175.00. Lots of color options and a variety of nibs.
Both of these have gold nibs, and the Pilot take cartridges or bottled ink.
The JetPens site lists the Lamy 2000 fountain pens as requiring bottled ink — but you actually use one. Do you think JetPens has this wrong?
I‘m curious, because I’ve used and loved the (far less expensive) Lamy Safari pens with oblique nibs almost exclusively for nearly 40 years, and I’m thinking about maybe putting a 2000 on my wish list. I’d be OK with the bottled-ink requirement, though I’ve found it useful to switch to cartridges in the Safari pens whenever I travel. But I‘d like to know for sure before going any further down that particular rabbit hole!
I have one and it’s bottled ink only, sorry.
Sorry, I skipped part of the text; fixed the post. The Lamy 2000 fountain pen is bottled only.
