I always take a multitool on the road, in the car. I carry a SAK Farmer because it is stronger than most of the standard Swiss Army Knives and it is lighter by quite a bit than the locking blade, larger models. I own a few of the lockers but very seldom carry any of them. I prefer the bombproof Farmer.
