Kai PRO Ceramic Diamond Pull Sharpening System, 3 Step Retractable Sharpener for Straight, Double-Bevel Blades, Knife Sharpener for Professional and Home Chefs

I have been doing my own knife sharpening as long as I can remember back to boy scout days. i am now in my 7th decade and have used a lot of hand sharpening tools, Smith, Lansky, chef's choice, worksharp,arkansas stones, diamond stones etc. For just out of the box, something recognizable in a kitchen drawer and used by those who dont sharpen knives as a hobby or profession this one made in Japan does as nice of a job as I have seen with 3 simple steps. For those who found this item bereft of sharpness I think they got a lemon or it was broken in some way. I did my wifes whole drawer of knives over christmas as well as my sis's; dependable, straightforward. The price was worth it when i sat down with my two adult daughters and they got the hang of it easily. So many features of so many sharpeners, this is a nice conglomeration from the grit on the stones, the stability, the angle of the sharpening surfaces. hell even the non slip inserts on the feet that hold it in place on the table top. Well made but light weight and the surfaces are kept shielded from kitchen drawer tool impacts by the sliding sheath. Well Done KAI

I got this in November 2020; it's now December 2023. It's seen a lot of use and is still going strong. The only caution I have about it is that it is set for the narrower, 16-degree bevel of Oriental knives and not the wider, 20+-degree bevel of American and European blades. (The trade-off is that with the narrower bevel, you get a sharper edge which dulls somewhat quicker. I prefer the narrower bevel, but as always, YMMV.) If you run an American or European style knife through this, it takes a while before the blade grinds down to the narrower bevel. But once you have the blade reconfigured to the narrower bevel, resharpening is quick and easy. Recommended!

Handy little sharpener for the kitchen. The sharpening mechanisms are well made compared to a lot of sharpeners. The only ding is that if you put moderate pressure on the knife the sharpening side flexes a little from the handle side of sharpener.

Kai PRO Diamond and Ceramic Retractable Sharpener- I use it weekly on my Japanese knifes to keep them very sharp.- It works great for the regular steak knifes and kitchen knifes.

I purchased this after my old knife sharpener damaged the edge of my Shun santoku, the previous sharpener was causing the edge to chip and created a 2mm deep gash in the blade. I purchased this sharpener after reading reviews but I was skeptical that it would repair the damage. After about 15 minutes of running it through the 3 stages the edge is back to perfect. Pretty impressive for such a small and relatively cheap sharpener. Definitely great value and salvaged my $200 knife.

I was a little dubious as I've used this type of sharpener with less than stellar (though not entirely unsatisfactory) results. My shun knives needed sharpening and though the company provides this as a free service one still must ship them off and await their return. So, I decided to give this a try. So glad I did. My knives now have a factory-quality edge for a reasonable price, a minimal amount of effort, and no wait for out and back shipping.

My Shun knives have been in need of sharpening for quite awhile, but I had not gotten around to sending them back to Shun for their free sharpening services. Given the under-$20 price of this sharpener, I'd give it a go. I followed the directions on the package and finished sharpening all 4 of my Shun knives (paring, utility, 10" chef's, and 8" santoku) in about 5 minutes. I did follow the curve of the blade as I pulled through the rough, fine, and honing stages. All are very sharp again and pass the ripe tomato test. I will note that while dull, none of my blades were chipped or broken along the edge.

Very good quality.

So when I first ran my Shun knife through it, I’ll admit I was scared. The first pull when I heard and felt the grinding, I had shed a tear. But with the second and third stages it was a lot smoother. The end result was my blade was as sharp as I first got it. Highly recommend.
