Rolling Knife Sharpener for Straight Edge, Knife Sharpening with Industry Diamonds Made Easy, Knife Sharpeners Kit with 15 & 20 Degree Magnetic Angle for Kitchen Knives

I love this sharper. I’ve used the pull thru sharpeners that didn’t do a good job. This sharpener sharpened all the knives the others messed up. You will need a leather strap to get your knife razor sharp. You have to listen when sharpening, listen for the sound to sound smooth. After using the 400 and 1000 diamond grit sides, you have to make one lite pass with the 1000 grit sides to hit rid of the very small burr, then use the leather strap. Don’t touch the edge or you will get cut.

This knife makes it easy to put a very serviceable edge on MOST knives. If you don't know how to use a set of stones its very useful. It does not however sharpen small knives easily, the magnet isn't strong enough to hold small knives above the magnet block for sharpening. Also it its completely unable to sharpen my chinese cleaver type chef knives, as they are too tall for the roller. overall its worth it to easily put a good edge on most of my kitchen and large utility knives, it takes little to no practice.

Very cool. Slick, does it's job, easy, and way cheaper than some of the fancy ones. Can't say if it works as well, but I have no complaints!

When it comes to knife sharpening, this product is probably the best blend of ease and effectiveness I have ever used. The magnetic hold keeps the blade at the perfect angle doing the hard part for you.

Magnets are not strong enough to hold blades securely. It works best on medium to large kitchen knives and gives a quick, very sharp result. Smaller and narrower blades are impossible to hold in place even when using a block to raise the blade above the top of the angle block. A few design changes and this would be great for most kitchen knives. Otherwise, it's attractive, sturdy and fun to use (on the right sized knives)

This sharpener is amazing... Seriously the easiest and most consistent sharpener I've ever used. I got this one because I wanted to see how these work... before I spent the money on a nicer name brand one. This one has been great. Weight to the roller is good. It rolls smoothly and is a good size in the hand. The magnetic angle block is the backbone for all of this... I wish it was a little bigger. The grinders could have a bit more quality... but therein lies the less expensive price tag. This is nice... and I'm going to invest in the higher quality set.

Although it does sharpen large knives well, it doesn't work for smaller blades such as fillet or paring knives. It is easy to use and comes with both a coarse and fine grit.

A bargain compared to the 'name brand' version and works so well. Brings otherwise useless knives back to fine order.
