I am gearing up for hunting after a long layoff and would like to ask a few beginner questions. I've finished obsessing over shotguns, and now am looking for a good knife. Would the Active Duty model be a good choice for upland small game hunting/camping duties? Is there any functional difference in the various blade coatings? How durable are the coatings, and can they be repaired if they get very scuffed up?
