In this video I’m putting the Gravitas Carbon Piston Black through its paces from a very specific angle: how it actually behaves for me as a lefty while I’m just… using it. This one’s been a slow-burn pen. The more time I spend with it, the more it’s growing on me, and that’s kind of the whole point here—this isn’t a “held it for five minutes and declared victory” review. I talk about what it feels like in-hand, why I keep wanting to reach for it again, and what makes Gravitas pens so fun to keep checking out. I also pair it up with Diamine Writer’s Blood and touch on the rest of the stuff that’s in my real-world rotation—paper and carry gear included—because the pen doesn’t exist in a vacuum. If you’ve been eyeing the Carbon Piston Black (especially as a left-handed writer) and you want a grounded, day-to-day take on whether it’s a pen you’ll actually keep using, this is that kind of review: practical, picky, and based on repeat use.
