Alexander Krivosheya, the co-founder of RoboRazor Studio, openly admits that he is not a knife person. “I’m not a fan of knives. But I have been working with metal since childhood.” But as an engineer, he wanted to create a useful, innovative tool and, as a video game enthusiast, Krivosheya is like many of us eagerly awaiting CD Projekt Red’s incoming Cyberpunk 2077. These two inspirations came together in the Inertix, a knife informed by cyberpunk futures that aims to be a daily carry item for the city dwellers of today.
For many people the Interix’s cyberpunk look will be the first thing that catches their attention, but knife enthusiasts will immediately gravitate towards the opening method. “It’s a very interesting movement, the highlight of the product, honestly,” says Krivosheya. The Inertix’s blade slides forward and backward rather than swings out from the bottom, but it is not an automatic knife. Instead, the blade rides on an internal arm that can be slid out manually, or engaged by looping a finger through the ring at the back end of the handle, making a whipping motion with the hand, and letting physics do the rest – the ‘inertial’ opening from which the knife gets its name.
Two separate levers lock the blade into place, and Krivosheya points out that the Inertix is not a gravity knife. “It does not open by itself, you can open it with a wave only if your finger’s in the ring,” Krivosheya explains. “Holding it differently, you cannot shake it out.”
There’s a deep connection between the cyberpunk aesthetic and Japanese culture, so it makes sense that RoboRazor settled on a tanto blade for the first release of the Inertix. Their take on the tanto starts off traditional enough, with a gentle transition between the main and secondary edge bevels – but there’s a twist. The blade’s swedge has also been sharpened, providing users with a secondary cutting edge altogether. The blade measures 1.89 inches long and is made from M390 steel.
The ergonomic design on the Inertix is relatively straightforward. Its handle has an exoskeleton-style look to it and is primarily rectangular. Materials are a mix of aluminum and stainless steel, with some titanium hardware. The knife weighs 3.88 oz. and, while it is clipless, RoboRazor has plans for a sheath of some kind for it.
Located in Kiev, Ukraine, RoboRazor is a collaboration between Krivosheya and Igor Fostenko, CEO of Enjoy the Wood, a company that makes wooden decorations and accessories. RoboRazor says the Intertix is just the start. They’re already entertaining the idea of allowing users to customize their own versions of the Inertix on their website, choosing from a larger or smaller size, different handle materials and blade shapes.
The Inertix project is already fully funded through Kickstarter, but it’s open for backers through June 3rd. The finished knives are expected to ship in September 2020.
