So I'm planning a month long hiking trip for next summer. I'm trying to reduce spening and the weight I'll be bringing, and was wondering if I should bother buying a knife. I'm for sure going to bring a folding saw, and will probably bring a small hatchet as well. Is there a point to getting a knife (would probably be the BK22 or the classic USMC KABAR) if I bring a hatchet? Or should I bring a knife instead of a hatchet? Or both? I have a fireman SAK, so I already have a longish blade that I could cut rope with.
