Sharpening Diamond Blades

First of all, what does "sharpening" mean?

Technically speaking, you are dressing a blade when it becomes dull, and then sharpening it.

Why do blades get dull?

Basically, because the soft metal bonds that hold the diamond in place on the blade melt on the diamond. When these diamonds are covered, they are unable to cut any material (concrete, tile, stone, etc.). However, if you sharpen them again, you can extend their life expectancy.

You can choose the method of dressing your blade depending on how long you want it to last.
