Usually a Spydie paired with a traditional slipjoint.
The models vary, but at the moment it's these:
If I'm out in the garden or doing yard work it'll usually be a tool steel and SE Salt Spydie pair.
If I'm out in the bush, I'll pair a fixed blade with whatever my main EDC Spydie is at the time.
Pairing a Spydie with the SAK Pioneer or Leatherman Skeletool also presents a very versatile and capable lightweight tool set.
When travelling overseas, a Dragonfly and a Leatherman Micra (where permitted) is a superb little pairing.
