I don't know about that in particular, but I EDC'ed a Spyderco Matriarch 2 with a ring for a long while. Very influenced by the karambit and sabit. Glad to have such a specimen, and I feel like there's some pretty easy things to do to keep the thing locked to your hand. I'd keep the ring on the third, farthest back joint of your pointer finger, because on that plane of motion, lots harder to hit yourself practicing. Just looked up yours, looks pretty good! Nice ring, no protrusions or anything to get static from, always a good option to give someone the ring instead of the blade when you can.
If you ever find how easy it is to sharpen karambits and feel confident in that, I would wrap some meat in plastic and then in a shirt, or get some soft material with a little resistance, and just slice it up, full "gross motor skill" style. Pay attention, try to think, but act, and see how you do, analyze and then do it again. You might find yourself wanting a serrated reverse-S, haha.
I understand it, there was a time when a light dedicated SD folder clipped opposite pocket of my spray is what I needed, along with me regular pocketknife. I try to consolidate more options into one or two things nowadays, but nothing wrong with dedicated pieces, and these are not as hard to sharpen as is purported should you ever go that route of sharpening.
In short: that's cool!
