Review on Mizu 1000 / 6000 Grit Premium Whetstone Knife Sharpening Stone Set: Japanese Style Waterstone for All Blades with Non Slip Bamboo Base - Complete with Angle Guide & Instructions by Sherry Meurer

Unlike other users, I found this sharpening stone unacceptable 1) Magnetic shavings formed during sharpening, regardless of the composition of the stone. If it's the knife, I've tried three knives: the Gemini Santoku, the Knife Master Chef's Knife, and the Yaxell Mon Chef's Knife, and they all have the same thing. During the sanding process, the 1000 grit started creating bumps and I had to stop. 2) The polishing side, 6000 grit, did not generate magnetic chips, but it had roughness, even more than 1000 grit, both sides of the sharpening surface. 4) Paper cut test, I found a jagged edge and caught the paper. 5) To make sure I got it right, I sharpen the above knives on a Cerax 1000 and finish them on a Choseara 3000. None of the symptoms of this stone exist. 6) I made a second attempt this morning and first used a leveling stone to remove small pits (some pits are too big and deep to smooth. Same magnetic shavings and more pits and bumps when sharpening. My conclusion is, that this stone is not suitable for sharpening luckily I don't have expensive knives I would not recommend this stone.
