  • I received the KnobbyKnife a couple of days ago and it works great. The video tutorial did a great job of getting me started and like others have mentioned after learning the technique it only takes about 10 minutes a tire. Thanks for a great product.

  • Received the KnobbyKnife and “sharpened” my first tire. Went riding and can say that the fresh edge definitely makes an improvement in tire performance. Actually was quite easy to learn the cutting technique. Thanks, a great product.
