Sharpening (Dressing) a Diamond Blade
Here is a helpful video on the process of dressing (aka sharpening) a dull cutting diamond blade. The purpose of dressing is to bring back the cutting efficiency of the blade itself. There are some causes to a blade becoming dull, some of which include "glazing" and "shedding." Dressing a diamond blade will restore the cutting capabilities of a blade in a fairly short time. Watch below for a video demonstration.
