I hate to carry things, so the only thing I carry in my pants pocket is a little knife, the aluminum beretta airlight. The LSH + twistie sits in my coat pocket.
However, to the question at hand, there have been uncountable times when I say to myself, why don't I have my Paratool or (now) Wave with me????
When I needed a screwdriver to take a basket apart at work, or a pliers to pull fat staples out of a box, to open a can with a defective pull tab, to tighten a screw in my glasses, and on. When I have it, I use it. And around the house, it easier to lug around than a toolbox, like pedalinbob sez.
go for it,
