I have had a similar experience. My Kaweco EF writes like a .38 Uniball Signo DX. On the other hand my Kaweco F almost writes like a .7 Pilot V7. I am really surprised at how bold the line is on the F. I wonder if the Blue vs. Black Kaweco ink makes a difference.

Are they smooth

Well, the Kaweco is a good pen. The Safari is a joke. By profit margin, it's far and away the most overpriced pen on the market, and is made of the cheapest material outside of China. In fact, most Chinese pens use much better materials, and, on average, have much better nibs. The Safari costs such an outrageous, almost criminal amount for what it is because when it came out there was almost no competition. It was well before the current fountain pen craze, and they could charge what they wished. Many jumped on the Lamy bandwagon because there was no other wagon in sight, and the rest is history. Pure hype make people pay several times as much for these pens as comparable pens cost. Worse are the Safari "Special Editions". These generally mean Lamy adds two cents worth of dye in a new color to five cents of cheap plastic, and charges thirty dollars extra for doing so. For the price they charge, for the immense profit margin they receive, Lamy nibs should be infinitely better than they are. The barrels should also be stronger. But I've received more requests to work on Lamy nibs than on any non-Chinese pen on the market. For that matter, more than on Jinhao, since Jinhao got its act together where nibs are concerned.

Be careful with that nib. The number one cause of damage I've seen to nibs comes from users trying to get line variation from non-flex gold nibs. Considerably more often than I see damage from dropped pens. You damage the nib just a little bit each time you do this. Even if you never spring the nib, you'll know instantly if that happens, damage is still being done. Eventually, the nib will get wetter and wetter, and/or it will start having hard starts, or it will start skipping, etc. Or you may just realize the pen doesn't write as well as it used to write. You probably won't have a clue why this is happening. The cause is trying to get line variation from a non-flex nib. Maybe you won't use this pen and nib enough for this to matter, but if you do use it on a daily basis because you love it, then don't try to get line variation. A steel nib can usually take minor line variation without much damage. Not a gold nib. Done too often and too long, a non-flex gold nib will cause problems.

Yes, they are somewhat inconsistent indeed. I have three M nibs. Two of those are like rather nail-ish F nibs and one is a softer, true M (on the finer side for European M) which I really like...

I think it is called Lamy Amazonite.

Thank you for your comment as it gives me a lot of perspective on expensive pens, as I will probably never buy them. Can you please let me know which pens are your EDC now and the ones that you enjoy writing with?

Which model of Jinhao do you have? Is it 9056 or 9035?

They all have the letter on the nib that states what it is 👍🏻

How how )) By increasing the slot on the nib !

Yep - it is magic. I love it - it is almost as good as the Jinhao 9019 medium heartbeat nib - almost.

😇❤️🙏

I now have my first Kaweco with a BB nib. It's very nice but was a little shocking at first on my ordinary writing pad. On my Campus paper it's amazing. 😍🥰❤️

I haven’t tried them because they’re 10x the price of the pens lol

@@PensandTea Thanks for responding. They don’t fit on the plastic ones I believe.

OK, just checked: I actually have two Broads and two Mediums.

I have the same problem with my EF pen. How did you make it smoother?

@@ignaciocalderon9751 I purchased Goulet Mylar Paper (Set of 2 Sheets) from Goulet Pens, and I followed Brian Goulet's instructions from one of his videos. In his channel he has lots of useful videos, it's worth checking them out. I hope this helps 🙂 The name of the video was Goulet Mylar Paper Tutorial.
