Voted >5. All screw drivers...I use the old style Craftsmans for my dirty work: 'impacting', prying, chiseling, etc. They wear out under that sort of stress. Broke a Mac driver that belonged to my grandfather putting serious torque on a seized bolt. With a wrench on the shank, the thing finally gave way right at the moment a piece of the tip cracked off.
I have a few waiting to be warrantied. Couple t-handle ball-end allen wrenches of various make (among my most frequently used at work), and a handful of sockets. The Snap-Ons I'll definitely swap out. The Matco I'm thinking of adding to my next load of junk metal...I tried out some of their sockets and, in my opinion, they're well suited to the scrap yard.
Anyone have any experience trying to warranty out stuff with any of the German companies? Our supplier at work sells almost exclusively German tools (chiefly Hazet, Stahlwille, Heyco, and Knipex) and while they are very good, I often wonder what sort of warranty, if any, they carry with them.
