I don't break tools often, but when I do,BANG! When you work on cars everyday, you come across stubborn fasteners more often, sometimes all that fits, isn't the "proper" size tool, so you cross your finger, and go for it, needing to get paid for the job and all.
What has often surprised me is, many times the "elite" tool fails, and a "lesser quality" Craftsman or even Harbor Freight tool pulls it off.

Yes that has happened more times than I can think of.
Which brings me to my latest conclusion Snap-on, etc...is more about looks and prestige/marketing bling, than ultimate durability. That's my final stand on those tools, but I offer it for the guys who think they NEED to "upgrade" to say SO, from Craftsman, etc... It really is not necessary. For all those who have to have truck brand tools, all the power to you

I used to be that way. But for all the guys that have not paid through the nose yet, you are not missing the "pot of gold", not having a full set of truck brand tools. So don't sweat it.
