Thank you for the TWSBI trick! That looks like a great middle option.

[@mkompan]

You’re welcome!

[@MothersHeartGypsyDoVe]

I have the same twisbi not sure how to change out the nibs. The first pen ..the noodles did you say looks like it gives more line variation with that nib compared to the twisbi.

[@BreakSpace]

Marc, thank you very much for this introduction tutorial, after countless KZbin videos on the same subject, this one was most helpful.

[@mkompan]

You're very welcome! Glad you enjoyed the video.

[@maxgainz8406]

for the 912FA you can get replacement feeds for like 20,- that make it an amazing pen. Or use different ink, the platinum carbon ink is so wet that I use the standard feed with it (I have both the 2 and 3 slit upgrade feed too)

[@mkompan]

I actually mention this in the video! The Flexible Nib Factory does great work, and they're developing their own gold flex nibs, which I'm looking forward to trying.

[@unice5656]

Your video prompted me to try swapping my FPR ultraflex nib out of the pen it came with and I'm super happy with the results! Thank you, I was having issues with inconsistent ink delivery and contemplating spending much more money on another pen.

[@mkompan]

Glad my video helped you out. It was that FPR hasn’t fixed their quality control problems. They seem to constantly put out new pens, but haven’t focused on the underlying issues with their nibs (other than the ink additive that supposedly helps with railroading.

You’re welcome! Those 52’s, if you get one with good flex, are really the best performing nibs out there.

I have the Fountain Pen Revolution Jaipur V2 with the ultraflex nib and an ebonite feed. They recently upgraded the feed and it is amazing. They are inexpensive, write very well and a joy to use. I have no connection financial or otherwise to the company but tout this brand because of how good it is and because of the excellent customer service from the owner, Kevin. You can’t beat the price.

[@MrCabimero]

PS I have put the pen down for days at a time and it writes no problem. The new feed makes the difference.

[@mkompan]

Thanks for the info! I just saw a recent review of the Jaipur V2 by SBREBRown and indeed, it looks like the previous flow issues have been significantly resolved. I’ve had nothing but good interactions with Kevin and FPR, so this is great news.

[@ALwinDigital]

I've gotten FPR Ultra Flex nibs (#6 steel duo tone) to work in an Asvine pen from Amazon. Unfortunately the Asvine pens come with plastic feeds that I need to modify by cutting a deeper channel for increased ink flow. Asvine sells replacement nib+feed units on Amazon so I purchased a couple of spare. I've ordered Ebonite feeds from FPR and waiting for them to come, to see if I can mod an Ebonite feed to fit into the Asvine. I am using the Asvine V200. I also have a Magna Carta Mag 600, I want to keep the original plastic/Ebonite body of the Magna Carta in pristine condition so I took out the nib and put it in another Asvine V200, also with a modified plastic feed. I had flow problems with the Magna Carta Mag 600 nib in the original body even after heat setting the Ebonite feed, and wasn't happy with the ink capacity of the included converter, so now the original parts aside from the nib are in their box. Cheap but very nice looking pen bodies with flexible nibs.

[@mkompan]

FPR now sells their ultraflex nibs in bock housing units, which are compatible with the Asvine V200. I bought one some time ago, and it works great.

[@ALwinDigital]

@@mkompan I didn't know about the bock housing units. I got the nibs before the Asvine from Amazon, trying to put the nibs in another Chinese pen on Amazon. Thanks for telling me about the bock housing version.

@@ALwinDigital sure thing. I failed to mention that these units have ebonite feeds.

[@ALwinDigital]

@@mkompan The Asvine V200 comes in 2 versions, Asvine nib version with a removable housing and Bock nib version which doesn't look like it has a removable housing. I assume the FPR Bock housing fits on the Asvine nib version of the V200?

[@RyanKirbyInks]

First off, great channel! There aren't enough channels that discuss fountain pens for drawing. One thing I'd recommend you try out is have a FPR Ultraflex reground to an XXF or Needlepoint. The result is very similar to a G-pen or Gillott 404. I personally did mine to an XXF and keep it in a Noodlers Kondrad with the stock Noodlers feed (the FPR feeds flood with ink to the point of burping), and it's become my go-to pen for sketching.

[@mkompan]

Thanks Ryan! Last time I gave regrinding a try I ruined the nib (it was a Noodlers, so no big loss), What tools did you use? Did you learn how to do it somewhere?

[@RyanKirbyInks]

@@mkompan I've ruined many nibs learning haha. Learned mainly from watching how some of the big names worked (Binder, Matsuyama, etc) and what their finished product looked like and tried my best to imitate it. I occasionally use a Dremel when I have to remove a lot of material (like adding flex), but mostly I use Arkansas Stones (3 grades) and 8000-12000 micromesh for the final polishing. I think I have another FPR Ultraflex laying around I could regrind for you, if you're interested.

[@mkompan]

@@RyanKirbyInks I would love to learn how to grind my own nibs, but at this point in my life I'm already stretched thin between teaching, art-making, parenting, and whatever this KZbin video making is supposed to be.

I have a Pilot Custom heritage 912 with the fa super flex nib with the cutaways on, which was excellent for 2 to 3 years until I dropped it onto the nib. I am going to the London Pen show to give it to a penmeister to get it fixed. I miss using it. It cost me £150 from a Hong Kong supplier. I'd buy another in a heartbeat if I can't get it fixed, and then take more care. The Con 70 converter holds a lot of ink and plastic feed is fine. I have a vintage made in 1950s England Conway Stewart 84 with a gold fine stub flex nib in green and black celluloid cracked ice finish. I bought it for £40 on ebay from a private seller in the UK. It is a beautiful writer and looks beautiful. For drawing I use a Platinum Desk pen with carbon ink cartridges. The ink is waterproof so I can use a watercolour paint wash over it.

[@mkompan]

Perhaps you can even get that penmeister can add extra flex to your 912. From what I hear it one of the best choices for added flex. And I agree, the Platinum desk pen with carbon ink is an excellent choice for drawing. I've had sitting around inked for months, and it has never dried up.

[@neilpiper9889]

@@neilpiper9889 Happy to hear it! The 912FA is such a lovely drawing/writing instrument. It was the first true flex pen I purchased (the Noodler's Ahab and the Pilot Falcon don't really count), and was what got me hooked on flex pens.

[@lessoos4434]

Probably one of the best comparison videos of flex pens on the net. Thanks. Quick question: Is it normal to still experience some hard stops on the Pilot 912 after replacing the feed from Flexible Nib? thanks

[@mkompan]

Thank you! Pilots usually don't have issues like this, but no feed isn't perfect, so yes, you might get railroading or hard starts. That said, give the feed a good cleaning to eliminate possible residual oils, and heat set it (look for tutorials on it if you're not familiar). it should improve the pen's performance. You might also try using a different ink.

[@luisguillermoperezmejia7907]

En la pagina que recomienda usted para los cambios de feed hay dos tipos de feed para el 912 y hacen mención a 2 referencias del 912. La NER y la ER. ¿Sabe usted en que consiste la diferencia entre esas dos referencias? Los feed serán diferentes ( a simple vista parecen iguales). Cordial saludo desde Medellín, Colombia

Hola Guillermo. Voy a contestar usted en mi Español bastante básico. Este negocio vende dos tipos de feeds para el 912, uno con dos hendiduras (912EN) y uno con tres (912E), que da un poco mas flujo de tinta. En mi experiencia, el feed con dos hendiduras ya da un flujo suficiente y escribe muy mojado. Entonces no se necesita un feed con tres hendiduras. Parece que ellos ofrecen feeds en dos colores, negro (912EN, 912E) y rojo (912ENR, 912ER). Saludos desde Los Angeles.

Thank you for this video! I love the FPR ultra flex nib but their pen bodies are terrible -- everything leaks no matter how much silicone I use -- and I didn't know what to do with my FPR ultra flex pens!

You saved me from tossing out a perfectly great nib!

[@mkompan]

My pleasure. I adore FPR nibs and it’s really sad that the quality control of their pens is so poor. They just recently started selling their nibs on Jowo housing, which allows you to use them in a large variety of pens, but I suspect that they’re not going to work great.

[@ina_lina]

@@mkompan Wait. why won't they work? A quality control issue? My favorite affordable pen body is the Retro 51. I'm a non-tinkerer and just want a flex/ultra-flex nib with an ebonite feed on a Jowo housing that I can easily exchange for the nib the pen came with. I was hoping this FPR was the answer...

[@mkompan]

@@ina_lina The issue is really with the design of the ultraflex, which makes it very picky about what feed it uses. The feed in a Jowo housing unit doesn’t have the flow or the geometry to work well with it, unless it’s modified. Since FPR doesn’t advertise their Jowo housing units as modified to work well with their nibs, I’m assuming that they’re just selling stock Jowo housing. A more effective option is to buy an Jowo compatible ebonite feed and housing from The Flexible nib factory. Their ebonite feeds have extra wide ink channels and work better with FPR nibs.

[@ina_lina]

[@MrAndrew1953]

Why does everyone overlook the Noodlers Triple Tail? Very hard to beat for line variation.

[@mkompan]

I didn’t have one at the time of filming, but you’re right, it’s a fantastic pen.

[@ZommBleed]

My pilot Falcon has a Con70 converter and there's an option for the FA nib. This would be the Metal Falcon, not the plastic Falcon.

[@mkompan]

That's interesting. Where do you get a metal Pilot Falcon with an FA nib? Seems to me that if you're looking to use the #10 FA nib it makes more sense to get a 912 FA or a 742 FA. Both can use the con-70 converter and are considerably cheaper than the metal Falcon.

[@ZommBleed]

@@mkompan I was just pointing out that the Falcon is available with the FA nib; mine is the Metal Falcon with the Con70. I spent the extra money to have a heftier Soft Extra Fine nib with the Con70. Afterwards I was looking for a pen with a more flexible nib in the same style. The FA fills the bill in a Metal Falcon. Yes, there are other options, and even much more inexpensive options. This is pretty much my grail pen for now. I have the Himalaya ultra flex in an EF nib, however there's nothing Fine about it. It's a very wet writer, which is good, and it flexes Ok I guess, but it's more like a Broad or very wet Medium nib. I might give the brand another try, maybe with a gold Fine nib. (With reverse writing it's pretty Fine, but very toothy and scratchy and flicks ink everywhere.) Recently, their online store was sold out of the Tanoshii Urushi-type pen that I wanted. They seem to be back in stock again, but not sure when I might place another order. Thanks for your reply and comment. (In case you're wondering, I bought the Falcon from Brian at Goulet Pens along with some Noodler's V-Mail African Violet--a really great ink.)

[@mkompan]

@@ZommBleed Thanks for your reply! So, just to clarify: you can have the standard nib on the Falcon replaced with an FA nib? I don't see that option anywhere, which is why I asked. How did you manage it? Are you perhaps mixing up the standard nib on the Falcon with the FA nib? The FPR #6 is a tricky nib, that doesn't work well in all that many pens. In some pens it writes drier and thinner, in some wetter and wider. I think the #5.5 is a better nib in that respect, in that it works well in a larger range of pens, and writes a little finer than the #6.

[@ZommBleed]

@@mkompan I didn't get the FA yet. It's just an option I was looking at doing when I was willing to drop some $$ on another pen. I did a lot of searching online to see which direction I could go. Getting a Pilot Custom is probably the best option for most. Thanks for the feedback on the FPR.

Hi Marc! I’ve got the TWSBI Go. Would FPR’s ultra-flex nib fit? I just received the 2 FPR Himalaya v1 pens with ultraflex that I got during their BOGO sale last week.

Which nib size do those Himalayas have? The #6 will not fit the Go, but the 5.5 nib might fit if you use a shim to keep it in tightly. I have a video on how to fit the 5.5 into an ECO, a pen that uses the same nib as GO. Have you tried heat setting the Himalaya? If not, there are a lot of tutorials on it on KZbin (even one made by Kevin). It usually helps a lot.

[@mkompan]

Hi Dorothy. Only the #6 nib will fit in your Ahab.

[@passthebutter3]

I like the aesthetic of the amethyst FPR Himalaya, so do you think it would be possible to do the opposite of what you’ve done: just exchange the feed on the FPR for an ahab feed? I didn’t see any twsbi 580 al feeds to buy separately, so I’m not sure that would be possible.

[@mkompan]

Just tried replacing the Himalaya feed with one from the Ahab, and it fits perfectly and provides much better (though not perfect) flow for the #6 nib. Comparing the two feeds, the ink slot on the Noodlers is a bit deeper, which explains the better flow. I have the ebonite version of the Himalaya V2 and am not happy with the build quality (perhaps the plastic versions are better), so I'm going to keep using the excellent #6 ultraflex nib in my Ahab. The TWSBI 580 uses the #5.5 nib, so its feed won't fit into a Himalaya.

[@Michael.Chapman]

0:33 I'd say the main reason I want line width variation via nib flex is: it's the way the most elegant cursive ever seen on the planet was created, in the eras of the quill, and subsequently the steel dip pen, introduced ca 1850 by Joseph Gillot. Good cursive disappeared due to the explosion of the fountain pen from ca 1890--modern manufacturers have let us down tremendously. Appreciated the great info in your welcome review :-)

[@mkompan]

I think the decline is more due to the increased focus in our educational system on training factory workers, and other roles not requiring fancy writing skills. My mother’s elementary school notebooks where filled with calligraphy practice. I believe only two years were dedicated to cursive writing when I was going to school. My son is going into third grade, and still writes in block letters.

[@Michael.Chapman]

@@mkompan similar here at school in Australia. When I grew up in the 1960s we were taught ‘modified cursive’ but in 1970s high school, all penmanship focus disappeared, everyone competed to develop the most affected, unique (vulgar non-traditional) ‘what-ever-you-want’ styles. My Mum was a school teacher-she wrote carefully executed cursive her whole life. Dad was a draughtsman/ engineer so wrote an amazing, very neat map-style hand-printing.

[@MothersHeartGypsyDoVe]

@mkompan I guess I was lucky I learned cursive very early before it was offered in school, actually. We still had penmanship classes with cursive at my school throughout the 80s. I absolutely refuse to give up my cursive. On the hunt for a decent pen that shows the full beauty of cursive writing.

Hi Marc! Great video! Would there be a way for me to repurpose a #6 Fountain Pen Revolution gold nib in another pen, such as you have showed with the TWSBI 580? Cheers!

[@mkompan]

Thank you, Phillipe! I've been thinking of getting an FPR #6 gold nib, and have been asking that very question. That #5 nib in the TWSBI 580 seems to be an anomaly. I've tried putting a #6 steel nib (which is the same shape as the gold) into my TWSBI Vac-700, and while it fits, the feed doesn't keep up. The steel nibs work very well in my Jinhao X450 and the Noodlers Conrad and Ahab, but I don't want to put a gold nib into a cheap pen body. I asked Kevin from FPR if the gold nibs will fit into Jowo housing (since you can buy ebonite feeds for those), and he told me they didn't, which is a shame, because I'd love to stick that nib into my Opus 88 demonstrator. I'm still researching this issue and will let you know if there are any developments.

[@Filip-pz7wu]

I've only recently gotten into fountain pens, and I really liked the line variation possible with a stubbed nib, what I'm looking for is a fountain pen with a flex nib / soft nib that can provide a somewhat similar writing experience. Is there a difference between soft and flex nibs? I know on some websites they offer a flex modification for even soft nib choices, so I'm not sure what it all means. I'm planning on getting myself a dip pen with different tips however to try out different types in a cheaper and easier way for now. My main use for the pens is studying, most specifically mathematical stuff, so some line variation would be neat for all the different symbols and such. I'd love some tips and recommendations to get me started with stuff like this!

[@mkompan]

Soft nibs offer a bit of line variation, flex more so. There's no consensus on where soft ends and flex begins. The question is how much do flex you need, and how much are you willing to spend? One thing to consider if you're using your pen for study, is that the "flexier" the pen the more ink it will put down, which creates problems on cheap notebook paper. Some flex pens (I'm looking at you, Noodlers) can also be "fussy" and I suspect that you don't want to be tinkering with your pen (or be worrying that it will burp) in the middle of your studies. I would go with a Falcon, or Pilot Custom 74 soft fine or Soft medium. Both are super reliable, give you some line variation to keep things interesting, and won't gush ink all over your paper. For Vintage, that Montblanc 342G is an absolute workhorse.

[@Filip-pz7wu]

Thank you for the swift response, I'm willing to spend up to let's say $350 maybe? Preferably somewhere between $200 and $300 I suppose, as I'm not too worried of spending a fair amount to make writing more enjoyable and less straining. Yeah, tinkering with my pen in the middle of it all wouldn't be great. Thank you for the recommendations though, I've seen the Platinum 3776 with a soft fine nib be recommended for the same stuff, how does that pen compare to the Namiki Falcon and the Pilot Custom 74 with soft nibs? Also, I'm still a bit unsure about the soft vs flex nib part, do you have any videos comparing their line variations? I'm guessing the flex nib will be able to make a bigger line than the soft one.

[@mkompan]

You're welcome! I have a video comparing the four different Pilot Flex in my collection pens here: kzbin.info/www/bejne/hmOYm4eaatF7hpI I would go with a Pilot 743FA, which you can get for about $250-300 in the US. It's advantage (besides its realiabilty) is that it's perfect for regular writing, and also flexes well. Some of your more flexible pens are only good for calligraphy, and are hard to control if you're not used to them. My pen reviews are geared more for people who draw with their pens but here's a review of it: kzbin.info/www/bejne/nIWUi4xrfMuUepo

[@Filip-pz7wu]

Thank you once again, I've watched both the videos and I like how the Pilot 743FA writes and flexes. It seems to flex really easily without a lot of pressure, which is great. I am a light writer as I often have to write a lot and I switched to needlepoint ink pens a long time ago because normal pencils / ballpoints just require too much pressure to write well with and are therefore straining. I don't think I'd have a lot of difficulty with something even flexier then. About the calligraphy thing, it'd be nice to get into, so I wouldn't mind a flexier pen either way. I'm fairly certain I could manage using it. Anyways, the ideal pen would be one that can have a large amount of line variation without too much effort to make for a smooth writing experience, I'm supposing the Pilot 743FA is fitting for this, but it would be nice with some other options as well. I'll definitely look into the Pilot 743FA more now though. Thanks a ton!

[@MujahidJazz]

Thanks a lot Marc. This video has saved me many days, maybe years of experimentation, and money too. I have only one doubt that I ask you to solve for me. If we are going to change the nib to a fountain pen, would it be better if it was Stub or Broad? I am a first time calligraphy and can only infer that the feeder for a Fine nib is different from that for a Stub. Thanks again for your advices.

[@mkompan]

I'm glad that you found my video helpful! I don't have a lot of experience with either stubs or board nibs, since I don't use them in my artwork. However, I'm pretty sure that in non-flex pens, the feeds for all tip sizes are the same. If a pen is writing too dry, there are ways to make it write wetter without adjusting the feed, such as choosing a "wetter" ink with better flow, or by making careful adjustments to the tines.

[@ichirofakename]

Thanks for the good info. So which of these flexers do you actually use the most?

[@mkompan]

Good question. The Pilot Falcon gets pretty heavy use, as does the Montblanc 342. Lately, however, I find myself reaching for a pen that I bought after making this video, the Pilot 743FA.

Do you know if any of the other TWSBI have the same feed as to accept the ultraflex nib? What do you think of Noodler's Nib Creaper? Have you tried Noodler's Triple Tail yet? I wonder how it would hold up in your comparison? Happy to have found your channel.

I'm glad you found the video helpful! Sadly no other TWBI model takes the FPR nibs. The #5.5 nib doesn't fit into the TWSBI ECO or the GO (come to think of it, I haven't tried it in my Mini-vac.) The #6 nib fits into the Vac-700R but the feed just doesn't keep up. I have the Creeper, and it's a nice little pen, with the same stiff, limited flex of the larger Ahab and Conrad. I currently have a vintage gold flex nib it, and it works great. I also have the Triple-Tail, and absolutely love it. It has a completely unique nib with very interesting properties, making it fantastic for drawing. It takes considerable pressure to make it flex, but it gives much greater line variation than the other Noodlers pens (perhaps twice the thickness).

@@mkompan Thank you for such a quick and thorough reply. Now you have me very interested in the Vac Mini option. I too love the Triple Tail and find it leads me in directions that I would not have considered before. Putting a vintage gold flex nib in the Creaper is a great idea too.

@@ad6449 You're welcome. Always glad to have a conversation with a fellow pen enthusiast. I just put the #5.5 FPR nib into my TWSBI mini-vac, and it works perfectly! What a great discovery. I'll have to do a video on it.

[@ad6449]

@@mkompan This is really good news. Yes a video please. Is the #5.5 a Jowo or their Ultra-Flex? I'm curious how the feed will keep up. A Vac Mini flex nib would be a dream indeed.

What is the noodler pen?

[@mkompan]

Noodlers is a brand tat sells may types of pens. The best known (and my favorite) is called the Ahab.

[@LinhNguyen-vm8le]

Hi. I just found your Chanel and finding it very useful. Thank you! New to fountain pens but really want a good flex pen that won’t break the bank. Tried Ahab but it was very finicky. Your suggestion on the TWSBI, do you mean the TWSBI Diamond AL? Do you know if your FPR would fit in any other Twsbi, or any other pen?

[@mkompan]

Thank you! I'm glad you found my channel. The TWSBI 580 AL with work with the #5.5 ultraflex nib. You can also use a TWSBI mini and Mini-vac. I've also had success in an Opus 88 Picnic.

[@LinhNguyen-vm8le]

Thank you! Will look into the mini.

[@LinhNguyen-vm8le]

I got the TWSBI mini with the #5.5 ultra flex and LOVE! The flex was amazing compared to the Ahab. Did wish the line difference was greater but still love the flex! I didn’t use it for a few days and now it’s railroading. Any suggestions on how I can fix this problem?

[@mkompan]

@@LinhNguyen-vm8le A few things can fix the issue. The first thing is to give the pen a good cleaning with soap and water to help remove residual oils that might be causing problems. If it's still railroading, you could try using a different ink. Most flex pens are notoriously fickle, and just work better with certain inks. Another thing that helps a lot is to "heat set" the feed. Yes you can actually heat set plastic feeds. While the feed and nib are still in the pen hold the them in very hot water (just under boiling) for about 20 seconds. Then squeeze the feed tightly against the nib with a paper towel. This allows the feed to make better contact with the nib and lowers the incidence of railroading.

[@LinhNguyen-vm8le]

Thanks Marc, will try your suggestions once I use up this ink.

[@ignaciopuente4347]

I loved your review! And I agree this saved me a LOT of experimentation. I have a question though. You said #5 nib on the twsbi, but on the FPR webpage there’s only #5.5 D: where did you get the #5 one?? Or is it the #5.5?? Thanks!

[@mkompan]

Thanks, Ignacio! You're right, the nib is actually 5.5. It fits perfectly though, so there must not be much a size difference.

[@re-crafted2993]

Just what i was looking for! Needed a pen for cartoon drawing on the go, and that twsbi -FPR combo looks sublime! Just to double check, is the nib rust resistant? Also, does the mod benefit from a top feed? A piece of tape is the classic ghetto mod, but i was wondering if you felt the nib benefitted from one.

[@mkompan]

Glad you found the video! That TWSBI and #5.5 FPR combo is pretty awesome. The nibs don't rust and work just fine without the tape trick.

[@Pamp81]

This great info. I wonder if FPR has fixed the feed issue with the HImalaya V2, because mine writes great, very wet, with the ultraflex nib. I also just picked up a Jaipur this week from them, with that same nib, and it, too, writes wet, with amazing flex. Not as pretty a pen, but that nib is so good. I had bought a Noodler's Ahab several years ago, and the nib is very stiff, but I cleaned it very well recently and heat set the feed, and it is actually working much better now, despite the fact that I have to push down so hard to get the flex. I'm thinking of replacing the nib with the FPR one, as you mentioned, but I might just live with it the way it is. I actually wish I had seen this video months ago! This is the best video about flexible fountain pens I've seen.

[@mkompan]

Thank you for your kind words! A number of people have commented that there have been improvements made to the Himalaya and the Jaipur, so it might be time to try them again, and make an updated version of this video.

[@JoseDelacruz-wo7ne]

Awesome

[@mkompan]

Thank you.

[@JennyEverywhere]

Great video! I know this is a necropost, but I wanted to share a little. I have that Ahab, and I also have a Noodlers Triple Tail. That's currently my most expensive pen. The triple tine nib is great. I do need to do the heat set for the feed, though, because I have to keep thumping the heel of my hand on something to shake ink down into the thing. It's not even a difficult ink, it's Noodlers Black. I just cleaned it with my ultrasonic cleaner with a touch on Dawn, to get any manufacturing oil off the surfaces. Now I need to heat set it, but there's tons on videos on it. What I really need, though it's some guidance how to look at a nib and know what style it is. I know nib manufacturers copy the style of another manufacturer, so it isn't good enough anymore to say "this is a Lamy nib". It might be a copy, so it's be more accurate to say "this is a Lamy-style nib". But what differentiates one company's style over another? What makes a nib Lamy-style, or Pilot-style? I know there's only a couple of manufacturers, then copycats or small manufacturers who actually license the designs, or just buy their nibs from the big shops. So what do I look for the determine what style of nib I'm looking at, even if it's a blank Chinese clone nib that only says "EF" on it?

[@mkompan]

This video is still getting plenty of views and people are still commenting…so how is your comment a necropost? :) As for nib types, this is very tricky because similar looking nibs are not necessarily compatible. There are three large western manufacturers making similar looking nibs but they for the most part aren’t interchangeable. That goes even more so with Japanese which are almost always proprietary. As for Chinese nibs, they’re all over the place some compatible with a few other pens and some not. That is to say, just because something is “lamy style” doesn’t mean it will pop into a Lamy. Rather than thinking of broad styles look for specific nibs you know will work with specific pens.

Hell bro them pens are mad expensive

[@mkompan]

I thought so too when I first started. But these things are not disposable, and will last a life time if you take care of them.

[@reitei1756]

@@mkompan but the ultraflex nib doesnt last forever isnt? How long does it last?

[@mkompan]

@@reitei1756 I'm not sure anyone can say how long an ultraflex nib will last since it depends on how and how much a pen is used, and this varies greatly from person t person. There are plenty of well functioning flex pens well over 100 years old, however, so while nothing last forever, you can expect a well built pen to work for many, many years.

[@reitei1756]

@@mkompan thank you for the fast reply. A few years lasting is good. I was just trying to find dip pen nib alternative. As it last me for just a week.

[@mkompan]

@@reitei1756 Dip pens don't have tipping and are prone to wearing out. In fact, in the past artists would use newer nibs for fine lines, and use older, more worn out nibs for thicker lines. Fountain pen nibs usually have very durable iridium tipping on them, which makes them smoother and longer lasting.
