It's not a "multitool" in the sense of being a pair of pliers with swiss army knives for handes, but a multi-function tool I EDC is the gerber prybrid. I seem to use it almost every day on random shit around the farm

>cutting net wrap on hay bales (dulls tf out of blades, replaceable blade preferred over ruining a pocket knife)
>pry open latch on old rusty bumper pull trailer that wont let go of ball hitch on its own
>scrape rust off a metal post to get a ground, pass blade across electric fence wire and watch for spark/listen for pop to check that fence is still live
>can strip electrical wiring, have used it to make quick repairs in the field before
>try to pull connection pins on portable corral panels, rusted in place. hammer grip and tap the bottom of pin w/ pry bar edge to break them free

it just werks
