Flattening Stones

Although all NSK stones are very wear resistant, these flattening/dressing stones are specifically formulated to counter the wear resistance and flatten at an impressive speed. They also work very well on natural stones as well, and the higher grit flattening plates will leave a scratch-free surface unlike many other diamond plates. The flattening stones are slotted to eliminate suction when rubbing against the sharpening stone. The flattening stones are also the best tool to keep the edges and corners of the sharpening stones rounded.

If needed, coarser flattening grits can initially be used on higher grit sharpening stones to remove material quickly, but it is recommended you then condition the surface of the stone with a higher grit flattening plate before use in order to prevent overly-aggressive surface. Each grit of the flattening stones can be used on several different grits, see recommended grit ranges for each flattening stone below.

Flattening grits: 200, 400, 600, 1000, 3000, 6000

Recommended use: Flattening grits from 200-1000 can be used on all NSK sharpening stones up to 1500 grit. All NSK sharpening stones with grits above 1000 should ideally be flattened with a grit as close to the stone's grit as possible. For example, a 3000 grit sharpening stone should be flattened with grits 3000 and above. If you do not have the ideal flattening grit for the sharpening stone at hand, you can condition the surface post-flattening with the included wafer, or with the available diamond nagura.
