Diamond Grit Types - Which to use?

DMT diamond grit types guide

By working through the DMT® system of progressively finer grits, you will quickly achieve a razor sharp edge on quality knives and tools. The DMT® diamond products are colour-coded for identification. In our product descriptions, coloured diamond shapes denote the specific grits in which each model is available.

Which grit you should use depends on... How often do you sharpen? How dull do you let your knife or tool edge get before you re-sharpen it? How sharp is sharp enough for you? Ask yourself these questions, and then read the grit descriptions (left) to determine which grit(s) best suits your needs. Hint: the pros use more than one grit & move from coarser to finer grits as they sharpen.
