My view [ and yes it is mine alone ] .The nice part in those knifes is they have two blades. Still there is an issue if you lost the SAK. I agree with a secondary knife, still a folding one. As a secondary i carry a FOX folding. Nothing special but i love his cut.
Is that I ALWAYS prep for the worst case scenario.
One that is survivable ,but likely not planned.
Winter storm,in spring.
Earthquake,tornado,SHTF [ manmade ].
Long list,but the + 1 is always on the plate.
Murphys law is at its best when no one is around to bail you out.
