The best pen(s) ever
I have been a fan of Fisher pens ever since they came out with pressurized ink cartridges for NASA. I still have one that I've somehow managed not to lose that I purchased decades ago when they first came out, which still works as well as ever. The new one was to replace another fairly recent one that I'd lost (which happens to most of my pens eventually). If you like to take notes or write on a sofa or in bed, they are terrific because they write at every angle that you might try are skip free and the ink seems to last almost forever. If you've ever tried to write on a piece of paper or journal laying down and holding it up to read, you'll know that normal pens require gravity to be in the "right direction" to work. (I also occasionally use one to mark lines on the ceiling, which I need to do every once in a while, when I move a light fixture or curtain track.) They are well made and usually not flashy if a bit expensive. If you can manage not to lose them or loan them out to someone, they seem to last forever. As to how easy they are to hold, it depends on the model. Some are a bit slippery, others are very easy to hold.

Bought pen. Received tank.
So I have never really been too picky about pens, but that was until I started flight school and university. There's a lot of pens out there that just can't take the pressure shock of climbing several thousand feet in a few minutes without leaking or failing in some other way, but this is not one of them. I was attracted to this pen by the fact that it is capable of writing in a vacuum, and in zero G, my assumption being that it would tolerate what some pens wouldn't, but by god does it go beyond that. This pen is built like a tank. You could probably run over it with one and it would look factory new. The difference in diameter between the exterior of the pen and the cartridge tells you everything you need to know about how much material is in the casing of this thing. This may lead you to think it would feel bulky in the hand, but the truth is, it really doesn't. As a matter of fact, it's actually one of the most comfortable pens I've ever used, and the tapered front end actually extends beyond aesthetics into ergonomics. It's capable of writing very quickly, and unlike some gel pens, it doesn't have that sticky feeling that accompanies cheap ballpoints. This thing will just go, and go, and go until you run it out of ink, which could take a while going on the size of the cartridge. The cartridge deploys with a light but satisfying click, and is very easy to replace. The matte black finish is nice for those that just want a solid, nondescript, tank of a pen, and there are no identifying markings on the exterior of the pen. As long as they keep making the cartridges, this will continue to be my pen of choice, even for day-to-day applications.

Solid pen. Wish it clicked nicer
Sturdy? Yes. Reliable? Yes. But I have two issues with this pen. 1) I hate the click mechanism because if you grip too high up the pen you will compress the spring while writing. Now, I don't always write like that but when I'm using a pen to quickly jot notes, sometimes I don't grip it as properly and so this becomes annoying. The click is also rather unsatisfying so if you wanna fidget with this pen your best bet is unscrewing and rescrewing the body of the pen, because the click is kinda disappointing. 2) I don't trust this pen. I have yet to have a leak in my pocket, but because of the nature of the design of this pen I'm worried it'll get clicked open when I put the pocket clip on my pants pocket and an hour later I'll discover a mess. I've yet to have that issue, but a traditional click pen design would seem more trustworthy. I don't like that the pocket clip is on the moving part of the pen. Overall? Solid pen. Has always written reliably when I need it. The body of the pen has a satisfying weight and the threads are neatly cut and it screws together very precisely. It's a rather small pen so if you have a big hands that might be an issue but if you want a small pen? This is a great inexpensive option. This has become my new edc pen and goes everywhere with me. I don't know if it's fair to call it a "tactical" pen because it doesn't have much grip and there's no fixed point to use for self defense, but I'm confident that the metal body of this pen is at least sturdy enough to push into someone's pressure point, should I be forced into a situation where I had to use it for self defense. But if you want a pen that definitely fit for self defense don't get this, but this might be better than defending yourself with your bare hands. All in all, a solidly built reliable pen.

Not so good

Es lo que promete, lo principal es que tiene buena escritura en muchas superficies y condiciones, su estilo es elegante por lo simple y la tonalidad de negro, el único pequeño detalle es que a veces se atora la punta de la carga cuando lo pulsas pero con un pequeño empujon se soluciona.

Ich besitze bereits den Fisher Space Pen Bullet. Super Stift, schon jahrelang. Allerdings durch mein Eigenverschulden weiss ich 90% der Zeit nicht wo der Stift ist. Teils auch jahrelang verschwunden bis ich ihn wiederfinde. Deswegen kam ich jetzt zu dem Entschluss "Kauf dir den grösseren, den verlierst ned so leicht" (Hoffe ich) Verarbeitung und Design des Stiftes sind schlicht und funktional, jedoch fühlt es sich hochwertig an vom Material. Ich persönlich wünschte mir aber eine etwas stärkere Feder in der Stiftmechanik, weiss nicht ob es nur mein Stift ist aber die fühlt sich leicht lasch an. Auch im Gedanken für die Benutzung über mehrere Jahre wie Schwach solch eine Feder werden kann. Sollte aber kein Grund sein zum Punktabzug sein. Ich werde mir einfach eine neue Feder besorgen. Kaufempfehlung? JA, wenn Sie nicht so schlampig sind wie ich und verlieren/verlegen, ist das ein Stift für ein lebenlang. Auch super zum verschenken!

Bolígrafo para uso diario, no es de lujo pero cumple con las expectativas.(No lleva identificación alguna ?) Buena calidad y funcionalidad, pulsador suave, ligero y totalmente metálico. Viene en caja de cartón, pero bien presentado. Sólo lo he utilizado un par de días y me ha sorprendido lo bien que escribe en cualquier ángulo, incluso hacia arriba. No sé lo que durará el cartucho de tinta, son caros. Pero si quieres algo exclusivo este es tu "boli".

This is the fourth Fisher product that I have purchased. These pens are the greatest. They perform under any condition. This particular model is very well made. I particularly appreciate the deployment mechanism for speed and ease. The refill can be operated with one hand. I highly recommend this product.
