This winter, when you drop down to one knee, remember there is never a substitute for diamonds. This statement becomes especially true when you’re out in the elements on your snowmobile. And no, we’re not toting around high-end jewelry, but rather diamond coated Carbide Runner & Stud Sharpening tools from BiteHarder. BiteHarder is currently revolutionizing the snowmobile industry by using our patented AdvantEdge technology to create incredibly sharp edges for your worn-down runners. The power behind our cordless drill bit applications comes from the strength of the hardest material on Earth – Diamonds!
