I am far from any kind of hunter, warrior, or wilderness expert. But one of the last things my dad and I did together, before he was completely paralyzed, was me learning how to sharpen knives. The Old Man was a ‘contractor’ back in the day as well has having a lot of time in the Army.
For a city boy (I did try like hell to join the Army, too deaf from an ear infection), any of my blades would surprise the hell out of those Manly Men. But yeah, most people don’t know jack about sharpening blades, even some who you think would. Easy to do if you find it fun and relaxing.
That same guy had a friend that invariably cut himself pretty good whenever he gutted a deer. It was the one day a year that he handled a truly sharp knife.
