My daily ink includes a fine point black Sharpie, a V5 ball pen and my old Shaffer student model fountain pen with a medium nib.
Just bought an entry level Lamy fountain pen today, to test. My 14 yo freshman daughter also uses a Shaffer.
I am looking at fine point nib pens, what are your favorites? Does anyone still use them? 40 bux or less as they might get lost.
On my Arc wallet I always carry a Lamy Pico, gifted by my girlfriend some years ago 
That’s what I use the most when I’m outside home/work. It is compact, writes well and, well, it was a gift that I really appreciated and needed 
I carry an old Fisher space pen I’ve had for 20 years or longer. Doesn’t actually write very nicely but it would write on work orders no matter what. When I could be in a clean environment I used a Pilot gel pen. I think this is a great thread
Sharpie’s are a must - absolutely essential part of any decent EDC kit, IMHO.
I like the Pilot G2 Bold Point, but they come in Fine Point as well. 
My real EDC pen is an Inka Pen (the original stainless steel version). I also carry a Kaweco Liliput or a Delike Hunyuan sometimes.
I also carry a Koh-I-Noor Versatil 5608 pencil most of the time.
I think pen threads are absolutely BLF addiction appropriate.
A few years ago I was Stumbling thru Krogers clearance section like Dchomak on crack. When my eyes came upon a BIG pile of these Pentel pens .
Pentel is obviously trying to close a 2 normal color pen deal by tossing in a 3rd colored one for free .
The 3 pack generally sells for about $5
I grabbed a bunch of these 3 packs for $0.50 ..or just under 17 cents a piece //108 pens for $18.00
I'm too penurious to be able to afford a pen.
Retro 51 pens
Pilot Birdy. Not a fan of normal sized pens as EDC. Although I also have a Zebra F701.
Paper Mate Inkjoy Gel - Turquoise
Sharpie Ultra Fine Point Marker - Turquoise
I keep a Pokka in my bag as a compact last-resort pen, but “carry” whatever clickies the bank’s giving out.
Replaced my broken Zebra F-301 with a F-402. Really pleased with it, nicest Zebra I’ve had, much more refined than the all steel cult classic F-701.
Came here to post F-701 
Haven’t carried a fountain pen in 40 years. Don’t EDC a pen currently but considering changing that. Probably will be my Fisher Space Pen. Have a recent one and one that was my grandfathers in the 1970s. Any pen that still writes fine after a half century qualifies for EDC in my book! (Don’t actually carry the antique but the modern one does not appear to have lost any quality.) Like the fact that it always works regardless of temp, moisture, position. Much nicer than a fountain pen. Granted the fountain pen can make nicer appearing script. However, I can barely write any more after so many years at the keyboard so I am just happy if anything I write is legible.
I love fountain pens.
The problem with them is now days you often have a forms that require pressure from the pen tip to make the duplicate on the second copy.
No can do with a fountain pen.
I have a Montblanc clone ballpoint that I put a fisher refill that I carried for years. Still have it. Take it when I think I need something nicer than a throw away.
Also, I actually write so infrequently that a fountain pen might sit in my pocket for a week(s?) unused.
So it’s whatever disposable pen I have at the moment is what I carry.
I have a cigar box full of pens collected across the years. From the schoolboy Shaffer on the bottom to Montblanc at the top.
I find vintage pens often write more smoothly than new ones.
I really like pens with a flexible tip that can be used to create a letter type that mimics the character style of old.
Light pressure = thin line. Heavy pressure = thick line.
I also like italic nibs. Easier to control but require holding the pen at an unnatural angle (for me) to get a nice letter style.
Most name brand pens have inflexible nibs and can’t do this. Some of the Japanese pens can to a greater or lessor degree.
The Noodler’s brand specializes in this type of tip. The tips are interchangeable (and cheap) and are meant to be modified to your likes. The pens are inexpensive too.
And if you think flashlight collecting is a deep rabbit hole - Ain’t nutt’en compared to fountain pens…
All the Best,
Jeff
My preference is a combo pkg.
1) Staedtler Maximum 1.6mm tip
2) Pilot HI-tecpoint V5 0.7 mm tip
3) Papermate Inkjoy 0.7 mm tip
4) Parker 0.8 mm tip
Grab a 402 and try it. They’re not expensive and nice to write with. The 701 feels cumbersome by comparison.
Pilot Vanishing Point fountain pen. Smoothness of a fountain pen, and clicks to retract.
Do you ever end up with a pocket full of ink?
