So easy to use! Best for Chef’s Knives and Santoku
I love cooking and I love knives, kitchen and others. I have a lot of kitchen knives and absolutely hate using a knife with even a slightly dull blade. Normally I’d take them to be sharpened 2-3 at a time as needed, but it’s hard to find the time or remember to do it when my knife guy is available. This is the perfect solution for between knife guy visits.I’ve never been able to figure out the standard long knife sharpeners that have been around forever and didn’t really know much about any other kind, so I was overjoyed to find this style. Truth be told this isn’t my first rolling sharpener. I had one and apparently made it sound so wonderful that my daughter borrowed it to “try it out” and as anyone with grown kids knows, those borrowed items rarely find their way back. So I figured I’d just get myself a new one since I’ve been trying to foster a love of cooking in her for years. Whatever it takes, right?It’s easy to sharpen your knife with this. You choose an angle (15 for Japanese blades and 20 for Western), magnet the blade to it, sharp side up. Then just roll the other piece back and forth, that’s it. You’ll want to apply a slight pressure obviously, nothing drastic, just enough to make sure the blade and grinder can actually interact. I usually do the tip while holding the knife so I can make sure the pressure is applied without pushing the main body off the magnet.Once you finish one side you flip it around and do the other. After using the more coarse side of the roller do it again with the other side to finish it off. That’s it. You’ll have a super sharp knife to use and you won’t have to go anywhere or pay anyone to do it for you. I couldn’t ask for more!

Wanted to love it but knives never got very sharp
I really wanted to like this sharpener as it looked so easy to use. I have a fancy electric sharpener that was recommended on wirecutter, which I love, but it’s a bit of a hassle to drag it out to freshen up one knife. First, the good. This is fairly easy to use – choose which angle to you want and attach the knife to the heavy duty magnet block. A couple of pointers – position the block closer to the front of the knife because the thinner part of the knife has a tendency to bend unless it is well supported. Second, make sure the knife is flush with the counter surface and not halfway up the block. In order to make it work for my knife handles, I had to move the handle off the edge of the counter.On the disappointing side, my two knives that I tested didn’t end up any sharper than when I started. I could see where the rolling grinder was taking away the metal edge but it in the end, my knife wasn’t very sharp. I re-did each knife a few times, thinking perhaps I didn’t give it enough passes/time to sharpen. After close to 10 minutes on each knife, decided that if it couldn’t sharpen it by then, it wasn’t going to happen. Perhaps your results will be better but for me, it was a great hope and idea that just didn’t execute well.

My favorite sharpener among all the tools I have!
This is so outstanding it’s almost frightening! It sharpens so well, so strongly, so fast, and even has a tempting a little metal ace card that makes you think you can be a ninja/gambit from the X-Men character. I haven’t dared to try sharpening that yet, but you know I’m gonna at some point. I have sharpened kitchen knives already, and I am interested in sharpening other of my tools that I have. I do wish there was a way to determine exactly which angle you should use by looking at your knife, but I’m afraid it’s sort of a guess. Overall, I think this is a very smart invention. It has a rubber ice at the bottom of the main base, and also has magnets for the blade to hold in place. Instructions are also convincing. You definitely wanna follow them!
