A New Approach to Diamond Plates

Whether you need them for sharpening or for flattening other stones, Atoma Diamond Plates have features that set them apart from other diamond sharpening stones.

Precision Placed Diamond Clusters
Instead of randomly coating the plate with diamonds, Atoma Plates have precisely placed clusters of monocrystalline diamonds laid out in a pattern on the surface of a stainless steel sheet. This arrangement creates a even, fast cutting surface more aggressive than randomly placed diamonds. And the geometric patterning creates channels between the clusters for waste material to collect, allowing it to get out of the way so the stone continues to cut without clogging.

Replaceable Abrasive Sheets

The diamonds are mounted to a 1mm thick sheet of stainless steel. This diamond covered sheet of steel is then mounted to a 10mm (3/8") thick piece of precision flattened aluminum. The resulting plate is reliably flat, sturdy and relatively light. And while the Atoma Plates last quite well, the diamond coated sheets are replaceable. Atoma Diamond Sheets Only are available in all four grits.

Practical Diamond Stones

Atoma Diamond Plates are Conveniently Sized

210mm (8-1/4") long x 75mm (2-13/16") wide, the Atoma Diamond plates are a great size, with plenty of surface area for use as sharpening stones or as lapping plates for flattening other stones.

Available in 4 grits

Depending on your need, you can opt for any or all of four grits:

  • 140 - for aggressive material removal reshaping edges or flattening stones
  • 400 - fast removal, but leaves a smoother surface
  • 600 - refines edges, smooths stone surfaces
  • 1200 - for fine edges or the smoothest stone surfaces

Thanks John, I am so glad to be working with people who know their products and how to use them. You have a very informative and well laid out website and I learned a lot. It was a rainy Sunday and I watched every video and read through each article. The information you provided was very helpful in teaching technique and helping me decide what to buy. Also your products are so well thought out, that no matter what stone you prefer (oil, water or diamond), there is a nice package available for a beginner. All of the products you put together each had their own advantages and believe me, each one spent some time in the shopping cart until I made my final decision.
