Knives I have with me when out and about:
A Swiss Army Knife of the large format with locking blade and saw (Rucksack or Trekker), scissors too if I take the Outrider.
A locking folder (either a Benchmade 940 or an RSK Mk 1 (Ritter Griptilian).
A 4"-7" fixed blade. . . depending.
There are LOTS of good knives to choose from in this category.
An axe.
I have a couple largish blades from
Fehrman Knives but rarely use them -- too big for EDC, too small to do serious tree cutting.
My opinion, YMMV
