After reviewing the Moleskine James Bond Carbon it was only natural to review my recently acquired Kaweco AC Sport Carbon fountain pen, so here you have it:

I’m not a huge Kaweco fan, mainly because their practically non existent filling system makes using them something of a pain. Cartridges are sometimes very useful (especially when traveling), but I generally prefer a cartridge based pen to accept converters as well and Kaweco’s Sport converters are a joke. They are difficult to fill and hold less than a drop of ink, and oftentimes come loose, so they’re basically terrible. Kaweco seems to be aware of that because they also make them difficult to obtain. You really have to want the pain to experience it (and believe me, you don’t. Save your money and buy yourself several cups of coffee).

So what possessed me to buy this pen? It’s pretty. There, I said it. That red, that carbon fibre — this pen is basically a Ferrari in pen shape: gorgeous and not very practical.

Look how pretty it is!

The nib is smooth and I was luck enough that it worked well out of the box. I’ve had mixed success with Kaweco nibs, so unless you’re comfortable dealing with baby bottom or flow issues I’d test the pen before buying.

The nib is also pretty handsome, and in this case a Fine, which is closer to a Japanese Medium. I got this pen on a closeout sale in a local art supply store so I lucked out on the nib, since you usually find Medium nibs in non-specialist stores.

I had a bunch of Diamine ink cartridges lying around, so I popped one in and gave it a spin. Here it is with Diamine Woodland Green, a very nice, well behaved ink with some shading:

The pen has a metal body but is not heavy. It can only be used capped (I have tiny hands so trust me when I say this), and despite its pocket size and rugged build, I’d never trust it, or any other fountain pen, in my trouser pocket. That way horror stories of stained pants lie.

Would you enjoy this pen? If you like the aesthetic, and are willing to compromise on ink cartridges, a steel nib and the price, then yes. If you’re looking for a daily workhorse or a practical pen, buy several Pilot Metropolitans, Lamy Safari’s, TWISBI ECOs or even a Lamy AL Star. This is a Ferrari pen — beautiful, frivolous and fun.
