I'm no sharpening expert, but I can reasonable sharpen most blades with my DMT diamond sharpeners. I have the black, blue, red and green of
this model. And the blue, red and green of the
conical rods for the serrations. I also have one of
these. One of the best things about these DMT sharpeners is that they are so light and small that you can get some into your vest pockets and you could say that you would have to end up naked to be without some good sharpening utensil.
