Wow, I absolutely love Ninja products but this Ninja Foodi NeverDull System Premium  German Stainless Steel Chef Knife and Sharpener made me love their products even more so! The chef knife has a nice weight to it and the blade is perfectly sharp! The Sharpener is so easy to use and works very well; I've not had any problems with it. I'm going to invest in more Ninja Foodi knives because this one is so awesome.
