My last serious outdoor adventure was a trip to Africa, climbing kilimanjaro and doing a walking safari. The three blades I took for my own use were:
Spyderco SE para
Busse basic 3
Gerber multilock
my daily carry is also a three blade set up:
SAK compact
Spyderco g10 standard SE or para SE
Nealy/Boker ats34 drop point in custom kydex
on a side note, the blade carried by the massai in Africa is a large *12-14 inch blade) fairly wide with a good point and a very simple wrapped handle. This seemed to be the only blade they carried, unless they happened to be touting a spear.
