Rounded knobbies? Think it's time for new tires? Not with the KnobbyKnife! This little gem will dramatically extend the life of your off-road rubber by adding a new, sharp, traction-producing edge to your old knobbies. You can even use it with new tires to try out custom knobby patterns.   

Assembled in Tennessee by some real good folks (we've met Mark & Jennifer in person), this is one of the standout products we saw at the 2012 Dealer EXPO. If you buy more than one set of tires a year, you'll save money. Look, it's cheaper than a single rear tire so give it a shot! 

Here's what they say: 

Knobby Knife is a powerful, 100-watt heating tool that maintains over 500 degrees heat while cutting rubber. With its patent pending blade made of high quality tool steel you will be able to quickly and easily sharpen the knobbies of your worn dirt bike tires saving you time and money as you won't be replacing your tires nearly as often.
