I received the Ninja US - Ninja™ Foodi™ NeverDull™ Essential Knife System 10 Piece Set from TryIt Sampling Company for review. This great set could not have come at a better time! I was down to my very last "sharp" knife and the only way to keep it cutting was to sharpen it daily. It was another chore. That all changed with this set! Its got the cool built-in sharpener thats so easy and quick to use! I love it! I also love the variety of knives and shears included in this set! I am getting a set for all of the cooks in my family this year for Christmas! Great functioning set of knives!
