When choosing grits for sharpening materials, how fine of an increment should one go with? I realize there is not just one answer to this, but when progressing through the grits, what is the optimum amount to change by? For example, if my blade was just honed with a 5 micron grit, and I wanted to get to 1 micron, should I bother with 3 micron, or just skip right to the 1 micron and put up with the extra time it would take? How about for some of the coarser grits? Thanks.
