5 Precision Adjust Knife Sharpener- 3-Stage Premium Kitchen Knife Sharpener to Repair, Restore & Polish Blades by Sharp Pebble

Sharpens perfectly. Simple to use. Adjustable angle for sharpening is a real plus.

it seems to work very well right out of the box. If it holds up in the long run, and I have no reason to think otherwise, it is a great buy for the price. It's versatile, able to sharpen blades from different countries of origin very effectively. It's simple, easy to use and does the job at a reasonable price.

Can get your knife sharp enough to cut paper, which means you can slice thru tomatoes no problem (breaks outer skin with no problem). Still have one knife that isn’t getting super sharp. I probably need to tweak the angle of the sharpener. I have a whet stone as well, but this gets them almost as sharp in seconds vs 30 mins. A good tool to have in the drawer for a quick sharpening before you need to slice n dice.

Very easy to use. Puts a nice sharp edge on all style of knives.

My kitchen knives were extremely dull. One of them wouldn’t even cut through the skin of a grape tomato. I purchased this knife sharpener and after watching a couple of reviews on how to use it I sharpened all of my knives and wow!, what a difference! These things cut through most anything that you need to cut up in your kitchen. I did what one reviewer said to do and that was to sharpen them a count of different times. I’m very happy with the results from this knife sharpener and would recommend it for someone looking for an easy , budget friendly way to put a nice edge on your kitchen knives.

We have a number of high-end knives and I normally use a wet stone to sharpen them. I have tried several of sharpener similar to this and they are ok for keeping the knives in shape but not as good as a wet stone. Well, my sharpener was wearing out so I tried this one for daily use and it is great. May never use my stones again. Well wort the price, easy to use, I could not be happier.

This knife sharpener is alright but after some time of using it, it showed itself to be less effective than initially thought. Edit: 12-16-2025 The sharpener is not very good for sharpening a ton and if you want emergency blades sharp and ready, well, I guess this might work but, the grits are not very good. Okay product, buy a Bxgnip sharpener and follow the instructions on the sharpening process carefully and you'll get your blades sharper than with this thing. Maybe use a leather strop but you'll be fairly alright just doing a sharpening and paper test.

Easy to use, only meant to pull blade through from one side. I read the directions after I’d used it incorrectly for a while but still works well.

I have always sharpened my own knives, on a steel rod or back of ceramic bowl. I always thought it was good enough until I tried the orange Ninja. Very easy to use, most of my knives fit the one setting so I could maybe got a cheaper version which has less angles, but this does scissors and even my serrated bread knife. It’s night and day, tomatoes slice like butter. And it holds it sharpness compared to my old methods. It’s sturdy, doesn’t slip, and you don’t need to put pressure, a few sliding strokes till you don’t feel resistance, start with coarse-medium-and then fine grit. It’s that fast and simple. So much better, what a difference! Highly recommend!

Can feel it sharpening

Can't adjust the angles, contacted producent after registering product but no one came back to me with advice or any information. Definitely not worth of buying. My advice, just return if it's broken and do not waste time, to not miss the return window.

I wished I had found this a long time ago before spending money on other tools to sharpen knives. I was close to buying a new knife set; however no need now. Works like a dream.

I would recommend this product for sharpening your knives at home. Easy to use and works great.
