I have to say this,
I've never carried one of these "multi-tools", even to the extent of never using a multi-bit screwdriver.
I was always taught that you have one tool for one purpose.
That sort of thinking would tend to make the Leatherman tool a "jack of all trades" tool, but a master of none.
I have a tool belt, but only put in it the tools I am likely to use for a given job.
I would certainly never use anything but an insulated screwdriver (or spanner for that matter) in a panel or place like that.
Please remember that these multi-tools are made for occasional use, not everyday use as a tradesman would require.
I carry a pocket knife with me on my belt, it's with me all the time that I'm wearing pants, I keep the thing razor sharp.
Just my $0.02 worth.
