Mark and Jennifer Evans, dirtbike enthusiasts, have invented a tool that not only makes tires last up to five times longer, but is economical as well. Knobby Knife allows users to sharpen the “knobbies” on their dirtbike tires to allow for better gripping performance. The 100-watt tool heats up to a toasty 500 degrees and features a patent-pending blade that easily cuts through rubber. The sharpening prolongs tire life, saving riders time and money. The tool rounds out with an insulated heat-safe handle.
