I am a big fan of my old-school Leatherman SupperTool, I have had it for 12+ years and have EDC'd it everyday for the last 3 years. I had the small flat blade screwdriver chip once (my fault) but I grinded it back. I really have been pleased with this tool. I would love a SuperTool 300 but can't justify it as my old one works soo well.
I vote if you need a "hard use" tool go with the bigger tools they generly use thicker peices of steel for construction.
