Italians!!!!
It took nearly a month for Knife Center to ship my order. I actually found a better price elsewhere and was about to cancel—but just as I was ready to pull the plug, they shipped it. In the end, the wait was worth it! I wasn’t impressed with how Viper packaged the folder, but honestly, what matters most to me is the knife itself—and wow, it delivers. Razor-sharp right out of the box, with a hefty blade that feels substantial for a folder. This piece has instantly become my favorite in my EDC collection. It’s the heaviest folder I own, but also the most stunning. Mr. Anderson was spot on—there’s absolutely no play in the pivot. Huge thanks to him for all the videos and insights on this model and others from his organization. Now I’m seriously considering a sturdy survival fixed blade—something low-maintenance, tough, and capable of holding a solid edge.

Finally, A Knife That Met My Expectations
I have purchased a few knives that cost over $150, and I've always been disappointed by some aspect of them. I know that is a low price for some people, but it's a lot for me. After listening to numerous KnifeAQ episodes, I wanted to try an Italian knife. When DCA described the Viper Oniro, it looked like it might be a good fit. I'm absolutely delighted with the Oniro. Turns out, DCA was right. The Viper Oniro not only has choice materials, but it was well designed and beautifully executed. The blade, made from stonewashed Magnacut, is an excellent shape with a nice belly for slicing. And slice, it does. It's a full, flat grind design with the sharpest edge of any factory knife I've yet seen--when I can slowly slice curving lines into loosely held paper, that's sharp! I also appreciate the rounded spine. It looks beautiful and is comfortable to use. While the blade wasn't perfectly centered, it was very, very close. The scales, made from burlap Micarta, are well-contoured and very comfortable and, with the ridging along the contours, has very good grip. On the downside, I have medium-sized hands. The handle fits my hands well, but just barely. If you have large hands, the handle may be too small for you--only you can know for sure. The lock is Viper's take on the cross-bar lock. I have not dismantled it, but the springs appear to be robust omega springs, although I can see very little of them. The springs are mostly hidden between the liners and the scales. The lockup is tighter than my other crossbar locks, including my Bugout, which has a very slight, lateral play when locked up. The Oniro has none. The action is smooth and quick, easily the best crossbar lock I've tried. While I tend to prefer an opening hole in the blade, the thumb studs on the Oniro are shaped and sized perfectly. They work well and don't get in the way. What I really like is the sound when opening or closing; it is fairly quiet but very solid. I have a couple knives that make loud clacking noises when opening or closing, but they sound hollow and cheap. The Oniro sounds like quality, like closing the door of a Mercedes compared to Chevy. The only item I'm mixed on is the pocket clip. On the one hand, it's a bit large and can be felt in my palm when holding the knife. On the other hand, it has been perfectly smoothed with rounded edges and has yet to cause pain. But what makes me actually like it is: I can place it onto my jeans pocket AND REMOVE it one-handed. The clip works very well. In summary, this is a keeper. Not only that, but I'm going to have to see if there's another Viper knife I can find that won't break the bank.

Nice EDC
I carry this everyday. The lock is sturdy, handle is comfortable. Opening and closing the blade with one hand is very easy and satisfying. Which has been needed at work quite a few times already. Both as a necessity and as a fidget toy. I've used it a few times with metal on metal contact to remove a section of gasket off a heat exchanger, and electrical tape off of tubing. No knicks in the blade. Still sharp. Haven't used outdoors other than making Marshmello sticks for kids. The belly of this knife is big. It's slices meat really well.
