-Here is a small insight of my philosophy.
For the military services, tactical functions and tools
for use on gear and equipment only:
The multi-tool or versatile knives alone are not
enough for the complete need during operations. The ultimate tools today includes one hand opening knife blade with locking function, scissors, wood saw, metal file, screwdrivers and basic functions. A rescue blade is of greater importance today. See Rescue blades.
It would be the safest method
that the individual persons in a team got a selection of tools needed for personal and tactical needs. Even so it would be necessary for the possibility for team tools. See Team tools.
I would recommend using multi-tools with the possibility for additional functions or the possibility for combination tools.
See Ratchet page and Leatherman
It would be of vital importance that the individual persons know how to use the functions and how to improvise. See improvisation page.
It is very important to go over all gear and equipment before-hand to learn what tools and functions
would be needed in a repair situation.
It is important that it would be possible to sharpen blades in the field. See sharpening page
