Mine I use most is a hammer myself . I seem to be using that most. But just observing my hubby ,I see him using the screw gun most often. He has loads of tools though .It really depends on the chore at hand ,what tool he will use most. He is a very handy man and does lots of projects.He built our whole addition on our house. Two bedrooms and two baths. He hates plumbing though .SO mostly he will hire a plumber. He did most recently though replace out comode.
