So I'm looking for a general purpose hunting, camping, hiking, and survival/combat fixed blade knife and I've narrowed it down to these two. I like the ruggedness of the short Ka Bar but am not a big fan of the obtuse grind, which I have heard makes it hard to sharpen. The USN MK 1 has a full flat grind and from what I know takes a wicked edge, but I have some concerns about the durability of the thinner blade and the ergonomics of the thicker handle. Which one do you prefer or why? And before you wisecrackers tell me so, no, buying both is not an option
