Orange Ninja 4-Stage Knife Sharpener & Serrated Knife Sharpener– Repairs, Sharpens & Polishes Blades with Ergonomic Non-Slip Grip

I wanted a simple and easy to use knife sharpener. I decided to give this one a try. I have a 17" chef's knife and it is difficult to sharpen. I unpacked the orange ninja and followed the instructions. The first time I did the 3 steps as described I was not so impressed. Remembering that I have not sharpened it or used it for several years, I decided to give it another go. I pulled it through the 1st step 10 times, then 6 times through the 2nd step, and finally 4 times through the 3rd step. I wiped the knife clean and did the paper test. I am very impressed with the sharpness of the blade and ease of the sharpener. I do not cook professionally anymore so daily upkeep is not an issue. This is a sharpener for good knives that get used occasionally in my house. Customer service is amazing! The angel is 20°/side, perfect for kitchen knives.

Sharpens really well but I dropped it and the knob broke off really easily. Overall not bad but not very durable

I really had my doubts about this knife sharpener, but I have sharpened every kind of knife in my kitchen and they are all very sharp now, it’s worked perfectly also very easy to operate 👍

I love this sharpener! Easy to use and gets knives sharp!!! The directions on how to use the serrated slot need to be improved. I used needle nose pliers to move the wheel to get to the sharpening slot. I wrote to the company for help and they did help and were very nice

It was good but could be much better.

Easy and quick to use. Did a good job of sharpening our knives.

works well nice hefty item, not cheaply made

Seems like a nice one. It feels heavy duty. I dont have any dull knives, so I can't attest to its effectiveness, yet. Time will tell. I bought if for WHEN I have a dull knife. The different settings feel very positive. They click in nicely, and feel like they will stay put. I like the rubber grip and rubber base. It won't slide out of your hand, or on the table. I think I made a good purchase.

Easy to use, got all my dull knives back to being very sharp. Was easy to use and comes with instructions for those (like me) who used to go back and forth with the blade haha. The handle is convenient, and I just place it on the table and sharpen my knives and it's sturdy.

Really good product. One that actually works effortlessly. My knives were very blunt but this item did the job!

Difficult to sharpen a pair of scissors with serrated edges. Otherwise for regular knives it works great.

The product is well made and works well even on serated blades

Nice & sturdy! Works great! My knives are very sharp!!
