Im 20 years old and dont turn wrenches for a living but somehow I manage to break tools all the time, Craftsman, snap on, mac, HF and others... gettin them replaced has never been the issue though. I have some tools that my great granpaw had in wooden tool boxes and I use them a lot!! Them old wrenches are 3 times heavier than any new wrench! I also got some old tape measures that my great granpaw had and they are more accurate than any new tape measure today! The best tools you can buy are at the flea market in the antique area. I got a good assortment of "Vintage" tools and never have broke a single one!
