when you guys go on a backpack hunt what do u guys use for knives or do u just have one and bring a sharpener? Im heading to alaska in sept and wondering what to do about knives i have about every kind of knife out there but should i bring one good knife and sharpener or a couple knives. i have a havalon knife that you can replace blades and if i brought that and one other knife do u think that would be enough. what are your thoughts.
