I've definitely broken more tools than I can remember.
I had a few Craftsman 3/8 ratchets strip the gears.
I've stripped my old FLF936 more times than I can count.
I've stripped my 1/4 Snap-on ratchet a few times.
I've stripped my Snap-on 1/2 ratchet a couple times.
Stripped out a couple Craftsman 1/2 ratchets in the past (one of them a friends; Whoops!

)
I've bent my 1/2 breaker bars, but never broken them.
Twisted 1/4 extensions (cheap Chinese) like spagetti noodles.
Twisted the end of a "Sears" (not craftsman) 3/8 wobble extension.
Broken a couple 3/8 universals.
I've broken 1/2 impact sockets large and small (with a 1/2 impact).
I've broken numerous 8,10,12,13 and 17mm deep well Craftsman and Snap-on sockets with a 3/8 impact. I've broken a 19mm once I think. I've broken short well sockets with an impact. I don't know if I break those less because the hold up better or just that I'm more prone to use a deep well socket. I normally don't use short well sockets unless I have to.
I've had a coupe cheap ball peens fly apart on me. The head and the handle.
I've bent the **** out of several lady's foot pry bars.
I've broken numerous o-ring type picks.
Broken the tips of several screw drivers. Some from use, some from abuse (chisel).
I've stretched the open end on a few wrenches; mostly smaller sizes such as 10 and 13mm. But I've never broken a box end on a wrench.
I've broken a vise.
I've bent C Clamps.
I've twisted my 6mm Snap-on regular length allen many times.
I've had several of my Snap-on torx bits break off; by ratchet and impact.
I've had several drill bits break. Usually when they get in a bind (my fault).
I've worn out a few drills (electric and battery powered) and a few air tools (impacts, air ratchets and die grinders).
I'm sure there is a lot more, but that is what comes to mind at the moment.
If you use tools daily, do your work in a respectable amount of time and like most, can't afford to buy every single tool you need for every job...
Tools are going to get abused and broken.
Chrome sockets get used on impacts, screw drivers get used as chisels and pry bars. Wrenches get locked together to turn bolts when you have a wrench that fits, but not a socket. Long allens get used in places where a stubby should have been used. Regular length drill bits get cut into short drill bits when you don't own a angle drill or don't want to pull a head to extract a broken exhaust stud. 1/2 ratchets and pry bars get cheater pipes when you don't own 3/4 or 1" drive tools.
All kind of "abuse" happens over the years until you can afford to build your tool collection. By the time you finally get every tool for every job, if that ever happens, you are now to old, tired and burned out to make the trip to the box to find the "correct" tool and just go at it with a adjustable wrench and a hammer.
That's just life.
