Any good multi-tool would work if it had the tools you need. I do like a one hand opening capability as I always seem to be holding in one hand what I need to work on and pulling the tool out with the other. It gets awkward. However, my Swiss Army Ranger gets a lot of use.
Depending on what cities you are in or will travel to, the fixed blade can be problematic, even if not illegal. I like the SRK, but might choose a shorter knife.
