Upgraded Rolling Knife Sharpener Kit Adjustable 10 40 Removable Diamond Stones 320 800 2000 Compact Portable Premium Knife

So far, I'm very pleased with this sharpener. It's highly flexible, allowing a range of sharpening angles and blade sizes, unlike many other "roller" style sharpeners (which don't seem as safe either). Also, it's not unwieldy like those countertop mounted swing arm options. It's much more compact that I expected too. Overall, I'm very impressed with the quality and it's half the price of similar options out there for the same value. And it works too! I was able to get a knife paper slicing sharp. I also appreciated the manual that came with it that outlined when to use different sharpening angles for different knives. Read more

Easy to use but I think it needs more sharpening grits Read more

It's a good sharpener for standard size knifes but is difficult to use for smaller ones Read more

At first I thought it was just poor sharpening stones leading to a mediocre edge which might still be the case. What really tipped things into the two star rating was discovering that the knife holder doesn’t hold the angle when applying pressure during grinding. That totally defeats the purpose. It gets more than 1 star because it did get a useable edge on a knife but definitely not as sharp as a factory edge that has been used for months. Read more

works well on 8" knives. not so much on small knives Read more

Great concept and I like the adjustable angles and height, but magnet needs to be stronger and/or bigger. Knife can wobble out of place, especially if the knife is large. Read more

This is a very well designed and inclusive knife sharpening kit. Its biggest strength is how it minimizes the learning curve, making it easy to maintain the most consistent and optimal angle for producing razor-sharp knives. The included instructions, with clear step by step pictures, make setup and use straightforward. The build quality is excellent. The solid aluminum construction provides a secure grip, giving you confidence while sharpening, and the strong magnet holds the knife firmly in place, preventing any slipping or unwanted movement as you glide it back and forth. As someone who is particular about keeping my knives as sharp as possible, this tool has quickly become indispensable. My only regret is not ordering it sooner. I’m very pleased with this sharpening kit and highly recommend it to anyone serious about maintaining their blades. Read more
