Best knives!!
I got these when I first purchased my home and they are still holding up nearly 4 years later! Still super sharp with the neverdull system. I like how everything has its own slot and can fit nicely on your counter.

Handle cracked after less than 2 months
Received as a Christmas gift, read the online care section. Said no dishwasher. Should have said no hot water. I let them soak after dinner in the sink. The 8 inch chef knife handle cracked. Not even 2 months of use. Not pleased

My best knives ever
They blend in with any kitchen. Their design is basic yet. The large pieces are slightly heavier. Everything is high quality. Their edge is out of this world, and it holds up well over time.

Everything my kitchen needs!
This block of knives has virtually everything I need to work on my kitchen! It has so many sizes and the knives work amazingly! I love that the handle is way to grip and doesn’t slip. I have not had to sharpen them!

Sharp cut every time
I love a good knife set! I also love anything Ninja brand! I have never had any issues with performance with Ninja! I love that this knife set has a built in sharper otherwise I would probably lose it. I always get a shape cut with no problem. The real test is when you go to cut a tomato nice precise cut every time. I do not regret buying this set.

Well worth the purchase! They are amazing!
These knives are amazing! They cut with ease & precision. The food scissors have become a staple for cutting up food for our toddler. They wash really well & the handles still grip perfectly after countless washes! The stainless steel blades sharpen easy with the built in sharpener & maintain their durability!

The knives are great, knife stand not so much
I purchased this knife set as a Christmas gift to myself and I must say that I absolutely love the knives. They are great in every way however the knife stand is not great. The stand itself is mostly plastic and due to the weight of the knife handles oftentimes will easily flip forward when even gently bumped towards the back of the knife stand. The very edge of the bas...

A purchase that is really worth it!
I am absolutely delighted with my new Ninja Foodi Never Dull knife system! Since I bought it, the experience in the kitchen has improved drastically.
What I like the most is its main feature: the integrated sharpener.
I totally recommend this product to anyone looking for comfort, quality and, above all, knives that last sharp.

Makes cooking a breeze
I recently got this set and it’s honestly made cooking feel so much easier. The knives are super sharp right out of the box and cut through everything smoothly; veggies, meat, even tougher foods. The built in sharpener is a game changer! You don’t have to worry about maintaining them or ever losing their sharpness. When you insert the knife to sharpen, it doesn’t come o...

An amazing knife set!
I love this knife set so much! It’s perfect for all the cooking I do and you can never go wrong with a stainless steel set, they are so easy to clean. The storage block isn’t bulky at all and suctions to the counter. I love the sharpener on the side. The knives are already super sharp and the sharpener helps them stay that way. They are also light weight and aren’t heav...

Useful
The durability of each of these pieces is impressive and the comfortable price that the affordable market has to buy and have it in each since it is useful for daily use in the kitchen

Great knives!
Great set! Knives are very sharp out of the box!
Handles and weighting of the knives have a nice high end feel in your hand. All that you need is in this one set.
My only gripe is in the plastic block. It’s nice, sturdy, and the knives fit well, durability of the plastic is my only concern, but we’ll see. The suction cups on the bottom work well and make it feel/work b...
