I’ve recently had the opportunity to use the knife at a friend’s and it is amazing! It is sharp and will cut through steel hahah. But in all seriousness it is a good knife and is sharp and perfectly shaped for veggies!

Really easy and safe to use

I really like this knife sharpener because I don't worry at all about the knife slipping and cutting my hand. Your blade is completely inside the sharpener, and all you have to do is slide the handle up and down. It worked on my knives, which are not Ninja knives, and the opening is big enough to handle my chopping knives. Glad I bought it
I would recommend this to a friend!

I love this knife. It is so sharp and cuts through soft tomatoes, Never need to ask my husband to sharpen my knife again, having the sharpener in the holder is very ingenious,
I would recommend this to a friend!

I’m so glad I bought this. I suffered a stroke and I can’t use my right arm anymore, so this is perfect for me.

Works great

[This review was collected as part of a promotion.] The Ninja Foodi Never Dull System Knife Sharpener works extremely well and extremely easily. It’s basically foolproof. I’ve had other sharpeners and sharpener stones, but this one works the best, albeit only on a Ninja brand chef’s knife. The 8 inch knife is also sturdily made and feels comfortable in my hand. It’s good to know it will always be sharp.
I would recommend this to a friend!

Awesome sharpener

[This review was collected as part of a promotion.] I have been looking for a new knife sharpener for a while now. After a lot of research I found the Ninja™ Foodi™ NeverDull™ System Knife Sharpener. It looked to good to be true. But this thing works awesome. When you push the knife into the sharpener it locks in so it cant slide back out. After a few pulls on tree he handle the knife is like new. There is even a unlock button you need to push and hold to get the knife out.
I absolutely love this thing. It works great and it also safe.
