Hey guys (and gals), I have a CRKT M16-14SFA and a Kershaw Blur that need to be sharpened. The Blur is my mulitpurpose knife and the M16 is my defense knife. What would be the best way to go about that? I know squat about sharpening, as I have only attempted on some crappy knives and a sharpening stone back in the day. Should I see if there is some sort of sharpening service given by the manufacters? Or can I do just as good a job myself? If so, what would I need? Let me hear some helpful suggestions.
