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.

Did a good job.

This well-engineered, sturdy, and easy-to-use tool has quickly become a frequently used and favorite in my kitchen, where I chop a LOT of vegetables daily. I like it and enjoy using it as much as my (now) ever-sharp knives. The only issue I experienced with this knife sharpener is not initially understanding how to use the "serrated" setting. Salma, the owner, sent me these WRITTEN instructions for how to use that serrated setting: -- One side of serrated knives is usually flat. The other side has the serrations (grooves/teeth). -- The white ceramic piece inside the serrated setting is a rounded ceramic rod, and it sharpens only one side of the serrated blade at a time. It can be rotated from side to side, depending on which side of the knife is being sharpened. -- The serrated side (grooved side) should face and make contact with the white ceramic rod. -- The flat side should stay against the opposite guide (orange/black side). As you gently pull the knife through, the rod fits into the serrations and sharpens them individually. -- So depending on your knife: -- if the serrations are on the right side, that side should contact the white rod -- if the serrations are on the left side, flip the knife so that side contacts the white rod You are not sharpening both sides at once — only one serrated side is being sharpened at a time.

Works great and easy to use! Knives are definitely much sharper afterwards. I don’t have to saw thru tomato’s anymore!

OK product, thought it would sharpen better

Very easy to understand the sequence of use and the fact that it sharpens serrated knives is a bonus’s bonus. Who doesn’t have some dull steak knives in their kitchen, I’ll tell you who, vegetarians. The base of this sharpener keeps it stable and lets you pull the knife through the 3 cycles. I have bc used sharpening stones for over 40 years and this is quite a bit better.

great for price... slight complaint with the serrated section as the ceramic piece in the center moves and needs to be straightened frequently in use

Very nice! I’m impressed with how easily and quickly this sharpens knives. I’ve tried all kinds: rods, stones, one that works like a sander, another with a fancy apparatus to draw the stone along the blade, even the knife manufacturer’s own expensive sharpeners. None of them, and I mean none, have impressed me like this one to quickly annd effortlessly put an edge back on. Even on a serrated blade. This is my new go-to, my quest finally over. Get one, I don’t think you’ll regret it!

Great product

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.

This is a great knife sharpener. I have used it already and it does a fine job. The attached instructions walk you through all the stages and it is clearly written. I should have purchased something like this years ago. It seems quite sturdy, should last for years.

Only used it once so far. But worked like a treat
