Almost everyone's knives could use some sharpening. The bottom line is, with every use, knives get a bit more dull — even the serrated ones. If you cook every day and you feel like your blades could use an upgrade and you'd like to invest in a set that will last you more than 10 years, this Ninja set is the answer. You'll never have to beg your friend in the restaurant business to sharpen your knives again, because this countertop wonder is so easy to use.

All you do is insert the knife and then swipe the lever on the outside of the block; the dynamic stone sharpening wheel will engage your blade at the perfect angle and apply the optimal amount of pressure to restore your edge to superior sharpness in seconds. It's that simple.

Having posted more than 1,200 five-star ratings, it's fair to say that shoppers are loving the Ninja NeverDull system. "The best set of knives we've used. My wife is obsessed and constantly raves about their sharpness and appearance. Would totally buy again!" said a happy customer.

Here's another testimonial: "These things are the real deal. Sharp and strong — my mother loved these. Honestly, I've yet to use a bad Ninja product yet."

"Bought this set for my wife and she absolutely loves them. They are so sharp, super easy to sharpen when needed and very durable. Highly recommend for anyone who loves to cook. They cut vegetables like butter," wrote one satisfied gifter.

"I was a little taken back by the price of this knife set initially but quickly realized this is one of those things where 'you get what you pay for'.... These knives are forged from one piece of metal and have stood up for a while now with no signs of dulling or rusting.... And holy cow they are SHARP! It doesn't matter what we use them on, they cut so clean and quickly. Frozen chicken, vegetables, steaks, potatoes...it doesn't matter. Every cut is clean and precise," said a rave reviewer.

Ninja's NeverDull Technology is built right into the storage block for professional sharpening results. According to the brand, the knives should maintain a razor-sharp edge for over 10 years.
