Some how I was always taught not to abuse ratchets.I would use a breaking bar ,or tee handle to loosen the fasteners. Then out comes the ratchet to remove the fasteners. In my thinking a ratchet is a speciality tool to be used that way.That way you don't run the worry about warrenty,or even a chance of injury .I under stand that ratchets now days are pretty tough but still it would extend their life,no matter the brand or quality of the ratchet.Some thing about grabbing a broken tool and hurrying off to the store,on a Sunday afternoon to warrenty a tool,that I could of used differently, just doesn't make sense to me.
