I am a real ball sharpening knives but who likes to have tools that work, this is a perfect accessory! The mini crock easy to use, the knife is pulled and we ask to be like to cut a slice, is repeated ten times and the operation in seconds (or even minutes to poorly maintained blades) is obtained again good edge! The blades are not scored so far and the mini fits in a pocket if you want to take her with anyone. So I intend to buy a second to leave in my car for my knife "picnic".
