I am in the military and have carrried a Leatherman and a Swiss Army knife on my belt since 1985. I just don't leave home without them. If I have to fly I put them in my checked luggage. If I am in dress clothes I carry them in my puter bag. As far as big tools I love my cutting torches, mig welder, cut-off saws and my big wood working tools. Tools and guns...ya just can't have enough. The cordless drill has to be the best invention in the last 50 years.
