Review on URBEST Sharpening Whetstone Sharpener Slip Resistant by Bruce Chinn

This sharpening stone is a waste of money. Through trial and error, I found that it barely sharpened any of my dull knives. The slip-resistant feature is the only positive .However, it doesn't make up for the lack of sharpening ability. I expected better from an industrial and scientific product. Save your money and look for a different sharpener..
