Wildlife ecologist (research). Mostly I work in S. Africa and Kenya. Leatherman, hands down, is the most commonly carried 'knife'. I carry a Charge Ti, most of my S. African colleagues and techs use Waves. Also, we have the heaviest machetes available locally. African hardwoods and rocks eat machetes. For the occasional wildlife mortality, or dinner, I have a Kershaw Packrat, plus a box full of butcher knives. Back in the office in Kentucky, a SOG Twitch II.
