A Sharper That Actually Works!
This compact electric sharpener has transformed my kitchen. It sharpens my chef’s knife, santoku, and even serrated knives with ease. The diamond wheels are incredibly effective and fast. Best of all, it's cordless—freeing you from any cords. Highly recommended for home cooks! Read more
Run away!
Power not! I’m pretty sure if you tried sharpening a paper knife, this thing would struggle. If you merely look at it, it stops. It took 20-30 minutes, and twice that number of attempts at finding just the right amount of less than zero pressure to get an embarrassingly poor result. Though it did help un “sharpen” a previous cobblers work and correct a long time problem edge. Read more

So simple, my husband actually uses it now!
I've been nagging for years about getting our dull knives sharpened. This product is a game-changer. The principle is incredibly simple - just pull the blade through a few times. The guided slots make it foolproof. I was shocked that my husband, who avoids all "complicated" gadgets, used it on every knife in the block. Now we have a full set of razor-sharp knives. It couldn't be easier! Read more
Useless Power Button
No stars. The first time I used it, it wouldn't turn off! We threw it in the garage until the battery eventually died. Plugged it in to charge and see if it would reset itself. Nope, as soon as it started charging it turned on by itself. Read more
