OK so at first this product was pretty good. However, once it needed sharpening, forget it. No way did any sharpeners work, the product just dissolved. And whatever it was made of would not "sharpen". I tried turning at the bottom to see if the product would "come out" to no avail. It was a total waste of money. Not very good after only purchasing it just over a month ago. With all the products out there, don't waste your time or money. It should only be a zero rating but I don't know if that works.
