I shared this in another thread yesterday, but appropriate here — this is my favorite all-around tool:

It’s a trail tool, but serves many purposes — from grubbing out weeds, to contouring paths, to leveraging boulders. I love it.

I also have a Japanese saw referred to as a human powered chainsaw (I think it’s called “The Silky Big Boy”) and it’s a close second. I use it to limb up trees to reduce fire hazards, prune larger branches, etc.
