Quality of the blades (which must makes knife sharp ) is too bad . Looks like ordinary steel coated with paint. You can see picture, i try to make sharp only one knife. Result : knife no sharp, blades are weared . I compare with same type of device, but other brand and more expencive, and my old one is too much better. I no advice to buy this , due to no sense to by device, if it dont work or enough just for few knives . On a picture of seller cutting blades other than real. They looks like high quality steel for cutting machine or ceramic, thats is should be, but real installed very cheap blades… only for children like a toy.
