The difference in quality between the $40 Lightning OTF and a $40 Chinese clone UTX is pretty substantial. The Lightning feels cheap, and doesn’t make a very inspiring sound. The Chinese clone I’ve handled was solidly built and fire hard. If you move up the price spectrum to the Ripper, you’re getting something every bit as nice as a Microtech for $150ish. Makes the UTX look very overpriced. And it comes with a tool for their proprietary hardware and some spare parts, which you don’t get from Microtech. My understanding is that you can send it back to China if there’s a problem, but it comes with the takedown tool, extra spring and screws, so you’re able to fix issues yourself. In my experience, the warranty is a non-issue. I’ve only ever sent in one knife for warranty repair, and it was my dad’s pinned-together Spyderco that I didn’t feel like drilling to convert to screws. Anything that you wouldn’t be able to remedy with the Vespa’s provided spare parts is likely so catastrophic that it wouldn’t be covered by Microtech’s warranty if it happened to a UTX.
