A lot of multi-tools knives have a simple 'V' notch in the base of a blade, that they consider a 'wire stripper.'
I have owned any variety of multi-tools over the years ... and they make a real nice collection in the bottom of a box, in the back of my storage shed. Even the best of them ... the Leatherman "Wave" .... is surpassed by a few proper tools.
True, you can't carry everything, or always know what tasks you'll encounter. Let me show what I start off with:
This little tool pouch ... it hangs from your back pocket .... will hold a few tools, usually enough for your routine tasks.
I routinely carry a screwdriver (Ideal 7-n-1), folding boxcutter, a Sharpie, and pair of wire strippers. Often,l I will add one or two more items.
The items most often added are a small (5") pair of Channellocks, a small (4") Crescent wrench, a #2 Square driver, a Sure-Fire flashlight, OR a nutdriver .... it all depends on the task at hand.
The key is having an HONEST assessment of what work is on the schedule. If you're busting pallets, then a pair of aviation snips is real handy. Otherwise, you'll rarely use them.
