I use diamond plates too and they work quickly. I also change the angle of the sharpened edge to a lower angle. My folder and wood chisels........i would not try to shave with them.

Yes, it very much depends on what you are doing with the edge. For 8 hour shifts of prepping veg/meat in commercial establishments, 21.5 degree angle works well for me. My machete that I use to clear brush gets a more robust and longer wearing angle.
