In 2016 I purchased my first Karas Kustoms pens, a grey Render K. Brad Dowdy said that the grey Render K is worth checking out, as photos don’t do the pen justice, and he was right. I love that pen and I still use it regularly, despite it having two minuses:
- The refill is a ballpoint, which I’m not a fan of.
- The cap doesn’t stay on. Ever.
So I relegated my Render K to desk use, and I only used it in my reading journal, where I don’t write as much, so I can usually wait a few minutes for the ink to dry.
The “cap not staying on” bit didn’t bother just me, and Karas decided that it was worth addressing. Their Render K V2 mainly came out to address that problem. When one of the V2 Render Ks in Battleworn finish came on sale on Black Friday, I decided to give it a try. And this time I got the G2 version, which accepts Pilot G-2 refills (my favourite refill, the Uni-ball UMR-85N is G-2 compatible).
This is the olive coloured Battleworn Render K, and though it looks heavy and hefty it’s super light. It’s much lighter than my old Render K, and more well balanced.
The “Battleworn” finish means that the pen was tumbled after anodization, and so it’s full of nicks and has an “old jeans” kind of look to the top of the cap, the threads, and the tip.
You can see the effects of the tumbling most significantly on the grip. The rings on it are pretty well battered and chewed. While it may look rough, the finish is smooth and there’s no risk of cutting your fingers on a raw edge.
The finish on the cap looks great too. The cap has an o-ring inside that makes sure that it stays on unless you unscrew it, and the threads have also been redesigned to make capping more secure. As in the old Render K, you can’t post the cap.
I was prepared to dislike the olive colour, but I like its subtlety. It’s interesting without calling too much attention to itself.

When you put the new and old Render Ks side by side you can see that they’re practically the same size, that the grip section has been redesigned, and that their threads look different.
The old Render K accepted refills through the top part of the grip, unlike the new Render K, where the entire grip section unscrews. I think that the new design is more streamlined and elegant, and in general the rings on the new grip make the Render K V2’s grip much better designed and less slippery to hold.
The old Render K feels much heavier than the new one, partly because I think that it’s not as well balanced as the Render K V2. However, it’s worth noting that in both Render K versions the grip section is a little on the thin side, so you might not find them well suited for long writing sessions.
The Karas Kustoms Render K V2 is one of the best machined pens in the market, and now that the cap stays on its a great EDC pen. I personally love the look of the “Battleworn” finish, and I highly recommend getting the G2 version of the pen and swapping the Pilot G2 refill with one of the many, better, G2 compatible refills in the market.
