Atoma Economy Diamond Stone #140

The newest addition to our wide selection of sharpening stones, the 3" x 8-1/4" Atoma Diamond Plates are manufactured by Tsuboman Ltd. and come in a wide range of grits to tackle any job. The plates are made in an unconventional manner – instead of having the diamond attached to a thick steel plate, the diamonds are fixed to a thin stainless steel sheet that is adhered to a 10mm thick aluminum plate. This makes the plate much lighter and easier to handle.

The 140-grit plate is used for flattening sharpening stones that need significant correction or heavy steel removal.
