I've been using tools all my life, fifty plus years, and own a lot of tools. It's funny, I have Klein, Milwaukee, DeWalt, Pittsburg Pro and Pratt-Read screwdrivers, maybe even some others. They are all in my roll around and are relatively pristine. I work a lot of HVAC and I have two screwdrivers I could never do without. One is a 9 in 1 reversible screwdriver which also has 1/4 & 5/16" nutdriver ends. I could literally completely disassemble almost any furnace or a/c unit with that thing. The other is a simple Pittsburg Pro screwdriver with a reversible long driver bit, with 1/4" slotted on one end and #2 phillips on the other. I take it everywhere I go and have two or three as spare backups. To me, I love a good, well made screwdriver, but I hate having to carry a whole slew of them, when I need several different sizes. A multi driver is just sooooo much easier to deal with. I can see where mostly mechanics would want a specific driver for the job at hand, but for repair work, I only carry a selection of screwdrivers in my backup tool bag, just in case, so far, I've not found the case for them.
