my dad started working for a stude dealer after WWII then went to the pontiac/caddy/olds dealer.started his own shop in 66 and retired in 86.so most of my tools got handed down and are 80 % snap-on.my tool box he bought new in 66 a snap-on and i have some cool old snap-on tools the local snap-on dealer has never seen or heard of.but 1 thing i learned the hard way.snap-on has a lifetime guaretee even if the chrome flakes off.well some of my dads old long wrenches the chrome flaked off so i turned em in for new ones.BIG mistake.i swear they make the new ones out of cheap potmetal.i never rounded as many bolts as i have with these new wrenches.
