I have several Ninja products and love them all! I’ve been having the NeverDull Chef Knife and Sharpener and it has not disappointed. It was unbelievably sharp when I got it. I’ve only had to sharpen it once, though I mush admit I want to sharpen it all time. It’s so neat. This system is truly premium!! Not only do I love how well the sharpener works, it’s also a great knife in general. The blade is made of top notch material and the handle feels comfortable in your hand. I will definitely be adding to this set!
