How to choose the right grit:
The grit that's best depends on a couple of factors. We suggest that you ask yourself these questions: How often do I sharpen? How dull do I let my knife or tool edge get before I re-sharpen? How sharp is sharp enough for me?
After asking yourself the questions above, take a moment to read the grit descriptions below to determine which grit(s) will best suits your needs. Hint: the pros use more than one grit and move from coarser to finer grits as they sharpen. Therefore our top recommendation is for you to consider one of the two-grits-in-one-tool models (Double-sided Diafold® Diamond Whetstones or DuoSharp® Diamond bench stone models).
