I trust myself and my training to use any tool properly within its design limits.
I use a wide range of knives and tools for all kinds of tasks. I don't use cutting tools for pry bars, screwdrivers for chisels, ratchets for hammers, etc. I'm not going to chop firewood with a Vic paring knife and I'm not doing food prep with an axe.
What is the least expensive knives I go wandering around the woods with? Moras, SAK's, Cold Steel Mini Bushman, etc. I can trust myself to use them properly and take a tool that is up to the conditions I might travel in. If I am day hiking with a group I might take something lighter and simpler than when I go solo and farther out for several days.
I do carry redundant cutting tools. I carry a go-to knife and also have single-edge razor blades, scalpel blades, and a mini like an SAK Classic or Leatherman Micra.
