I have the Ninja Foodi NeverDull System Premium German Stainless Steel Chef Knife & Knife Sharpener and as a person who always has to wait for their husband to get the sharpener out on his time, this is great to have one available at all times. Let me tell you, that this bad boy is very sharp. My finger vouches for it. I debone pork butts quite often and this knife just slid though it like butter. I am in love! I need more!
