This pen is TINY! I was surprised that it is so much smaller than the normal pen. It might work out for special uses, such as inside a journal or kept in a pocket. It isn't what it looks like in the picture. it is 4.75 inches long, very light, slim. Just a notice to other Jet Pen shoppers!

It is a good pen. Not the best but certainly not the worst. Comfortable to use but the ink flow is not as smooth as I prefer.

I like the form factor since I have relatively small hands, but I would suggest the .4 over these. The pen does make fine lines but the writing experience is really "scratchy" and not smooth like I am used to with Pilot gel pens.

In comparison, the Signo Bit .18 is much finer but writes much "smoother" than this pen. Go with the .4 for a smoother writing experience.

This pen was fine for a while and wrote very well for the first couple weeks, then as i was writing gently the tip got destroyed and it just cant write at all. I would not recommend this pen.

Pros:
- Good looking, good size for a purse pen
- Writes in a very fine line...when it writes

Cons:
- The clip is way too tight. I tried clipping it to a couple sheets of paper. It was difficult to get on and left a crease on the paper after I removed it.
- The pen skips a lot. Regular Hi-Tec C's occasionally skip/get clogged, but this pen was horrible.
- Ink runs out rather quickly, and considering the price of the refill and the amount of ink you get, there are much better pens you could buy.
- The barrel is really slim, as expected. I didn't mind this, but I imagine that people with larger hands would find this pen uncomfortable to write with.

Overall, a very disappointing purchase.

This is my favorite pen. I have had it for 2 years and despite using it all the time it is still in great shape. Every time I have refilled it the new ink cartridge has worked perfectly. In 6 or so refills I have never had any troubles like those described in the other reviews.

This is a nice small pen, great for pockets. I have small hands and find this a very comfortable fit.

I originally bought this pen in Japan and was seriously bummed when it ran out of ink. I am very glad to have found JetPens and lots of ink for my best pen!

I liked the size of this pen however I did also find that after a short time, the ink flow diminishes/fades and would then completely stop working. It happened twice. Its disappointing especially when there is a full barrel of ink clearly left and I wanted so much to like this pen.

I have used this pen. Very fine lines excellent, and looks very neat on the piece of paper but after sometime the flow of the ink starts to diminish. Could it be the different paper material. The barrel is too thin to hold.

This is the worst pen I have ever used in my life. It is worse than BIC pens even. The ink does not flow well at all. It often skips. Additionally, it is very, very scratchy. Maybe the 0.4mm is better, but I am not willing to take a chance.

The ink does not flow smoothly at all

When i first got this pen, i was highly disappointed; the pen was scratchy and the tip felt as though it would not last against my notebook paper no matter how softly i tried to write. However, i bought a new notebook with smoother, nicer paper and i don't like to write with anything else! it writes thin but there's no scratching and i no longer feel as though it's going to break when i use it. i do love this pen, but i don't feel it's appropriate for regular notebook or loose leaf paper.

I love this version of the hi-tec c. It's a more comfortable pen then the original, however it runs out of ink very quickly. I have had it about 3 weeks and already the ink is gone, it makes me sad on the inside. Buy extra ink refills!!

This was part of my first JetPens order!

I love the Hi-Tec-C line (G-Tec-C here in the USA), but am generally not a fan of capped pens. When I found this pen, I thought I'd found the perfect little writing instrument for me.. While it is a good pen, it is definitely not my perfect pen. The ink is smooth, as expected, but the barrel is much smaller than anticipated. The barrel is approximately the same size as a G-Tec-C without its cap. However, the Slim Knock feels smaller in diameter than the G-Tec-C (I could be wrong, though). Additionally, the Slim Knock feels basically weightless to me (something I don't care for).

Despite the points above, the pen is great for those that are looking for something compact; the pen would be great for slipping into a small wallet.

Pros:
- Good looking, good size for a purse pen
- Writes in a very fine line...when it writes

Cons:
- The clip is way too tight. I tried clipping it to a couple sheets of paper. It was difficult to get on and left a crease on the paper after I removed it.
- The pen skips a lot. Regular Hi-Tec C's occasionally skip/get clogged, but this pen was horrible.

Truly, one of life's perfect pens. It's smaller, lighter, slimmer than you think. Incredibly precise, of course. It has a soft rubber grip that is most like firm silcone. I only wish it had a larger ink supply...

Just got this pen today REALLY not what I expected. It writes well bit the length is a mini pen. I thought this was a full length pen and greatly disappointed with it. If you just want a pen to put in your glove compartment OK but not to write with on a daily basis.

I'm starting to understand the love affair people have with the Hi-Tech-C pens. This is my first one and I've already got a decent crush going on this pen. The .4 tip is, for me, like the Goldilocks of of pens: not too fat, not too thin, but juuust right. It's not scratchy at all but the line looks sharper than some of my .38s.

The only thing I don't care for so much is the slim barrel. When I added this to my cart I didn't really notice that I'd chosen the Slim Knock so I was a tad surprised when I first held it. I have medium-ish sized hands and it feels too small to me. Writing with it for an extended period of time is tiring because it's smaller and less balanced than many of my other pens. That said, the rubberized grip is very comfy.

I'll definitely be shopping for more Hi-Tech-Cs in the near future.

I would agree that the pen could be slightly bigger for comfort reasons - but for a micro-sized pen, perfect for your purse or small notebook, you really can't get better quality when it comes to tip and ink flow!

This is really a cool pen to use considering that it is only 0.4mm. I really love how smooth it is compare to the others micro pens I used. It doesn't skip at all. I don't find it that scratchy as well.

Although I would love the pen to be slightly larger.

Very good petite pen - perfect for keeping with a planner or checkbook. However, slightly too small to grip comfortably, and the ink is a little bit scratchy, making it hard to write quickly and neatly.

This is one of my favorite pens to keep with my planner in my purse. I love the grip and the size. It doesn't take up much room at all, but it's long enough that I can hold it comfortably even when I use it to write a full page. I just wish that the refills came in pink, too.

Highly recommended!

I've gone through 7 of these pens now. I love them. They consistently write the same every time. The ink ALWAYS 100% of the time flows without skipping IF YOU WRITE SMALL, like the pen was DESIGNED to do. These pens are designed for writing extremely small. Can I say that again? SMALL. If you write big, the pen WILL SKIP.. surprise!

Pros:
Writes extremely small :)

Cons:
The ink runs out quickly.
It will skip if you don't use the writing style it is designed for.
The ink is NOT water proof / chemical resistant / paper impregnating.
The pen is very little. If you are used to regular sized pens, it will take some getting used to.
The clip is extremely sturdy; will rip standard paper

Too small and insubstantial for my liking. Could be great to keep clipped to a checkbook or a small journal or something, but it's very light in weight and small in size.

I feel like it gets lost in my hand, and the very fine 0.3 mm line only adds to that effect.

I writes really nicely, though. I wouldn't discourage anyone from buying it, especially if they like a really small and slim pen.

Overall, I like this pen. If you don't mind the small size(and it is very small) it writes just like a regular Hi-Tec-C. I haven't had the problems that other reviewers have, will update if I encounter anything!

Pros:
- Good looking, good size for a purse pen
- Writes in a very fine line...when it writes

Cons:
- The clip is way too tight. I tried clipping it to a couple sheets of paper. It was difficult to get on and left a crease on the paper after I removed it.
