So I am looking for a knife to fill the role of a bushcraft/hunting/survival knife that is smaller than the kabar or srk that I have always used. I want something smaller now. The only thing holding me back about the gunny is that it is a convex edge and I have never had one of those before. What differences should I expect in performance, edge retention, and sharpening techniques? I have to be able to sharpen it in the field. Although I never carry only one knife I need it to be that reliable. Tell me what you think.
