Leatherman Juice Pro here. I use it almost every day, mostly the knife & pliers, but the tweezers, screwdrivers, and scissors get used about once a week.

I see the people saying why carry one - if they need tools they'll just go to their toolbox. I do that too, but having this saves me the trip, and on more than one occasion, lots of time. I've done roadside car repairs with just the Leatherman, and around the house it's nice to have immediate access to a capable set of tools without searching. I've even grabbed the wrong tool, got to the top of the ladder, and then just used the Leatherman because it was there.

You might not realise how often you really would use these, and they barely take up any room.
