Review on Durable Atoma Diamond Sharpening Flattening Whetstone for Efficient Blade Polishing by Mark Clark

was previously used for lapping (aligning) the back of two chisels. Pro: The 140 grit is definitely coarser (and faster) than my existing 300 grit (diamond) and 220 grit that I've already used on clocks. Better to use 140 than go to 220/300. then move up con: crushed stone is applied to a thin aluminum plate. it feels like you can click it like a map. necessarily flexible. should have read ALL the reviews. definitely not what I expected to have other diamond stones weighing like a brick. The Atoma leveling stone for leveling water stones is also thick and heavy. However, you can compensate by placing something else flat. that is, granite tiles, glass slabs, other thicker flat diamond stones.
