Review on Kamenda Sharpener Sharpening Whetstone Frinding by Carrie Morris

They are curved enough to be easy to see in photos but very poor for sharpening. When sharpening we need a FLAT surface. I bought them primarily for reprofiling to avoid wear on my premium Venev diamond and CBN stones and my Atoma stones on cheaper knives that don't need a pristine edge. I didn't expect much from them but I expected them to be right as this is extremely important. This causes the edge to bulge when I make flat bevels. I'm not happy with them at all, like I said I wasn't expecting much as they would last a very long time or stay true to the hardness but I did expect them to be flat.
