The Atoma #140 is the go‑to diamond‑lapped plate used by professionals for both stone maintenance and knife repair work. Its fast cutting speed makes it ideal for flattening whetstones, removing chips, and reprofiling edges when significant material needs to be taken off quickly. The plate’s patented design helps prevent clogging, allowing it to maintain consistent performance throughout long sessions.
This model includes the aluminum base, which provides stability and ensures the plate stays rigid during use. Because diamond plates do not dish out, the Atoma #140 retains its shape over time, making it a reliable long‑term investment in any sharpening setup. Many sharpeners consider it an essential tool, especially if they regularly maintain coarse, medium, or finishing stones.
In addition to stone flattening, the #140 is frequently used for knife repairs, where controlled but rapid metal removal is necessary. After repairs, users typically transition to medium stones such as Shapton 1000 or Shapton 1500 before moving on to finishing stones.

Why is the blade length different from the displayed size? The size in the product title is a nominal reference used by knife makers. The actual blade can be slightly longer or shorter due to handcrafting and traditional sizing. Each product page lists the exact measured length.
