I have this same cutter sitting here on my desk, my daughter bought it for my birthday. It replaced the one that got stolen from my car.
I have loved this cutter since the very first time I laid eyes on it, and still love it just as much every time I pick it up. It's my very favorite of all the Xikars, and I even had the mammoth bone cutter. That thing was super cool, but I still like the Spectra far more, so I ultimately sold it.
Since it's impossible to not mention the Palio in the same breath, I'll say that I just like Xikars better because the Palios pinch me in the web of my thumb and make me bleed, while Xikars don't. So far as cut goes, I'm not too anal about that. I'd just use my teeth (and sometimes do), but I have dental work and I always fear I'll screw it up from biting caps off.
All that to say that of all the cutters, and I think I've seen a good percentage of them, if not all of them, I think this is easily the prettiest. The cool factor has made me smile time and again for a couple years now. That's hard to beat.
