Sorry if this post is not exactly on topic, but I ran into this issue while working on a lawnmower engine. I pulled out my Sears Craftsman micradjusting torque wrench (makes a click when you hit the right torque) and it was totally jammed - would not click and the adjusting handle would not turn. The last time it was used was decades ago when I lent it to someone. That'll teach me to do that! This would have been an issue years ago when all Craftsman tools had a lifetime warranty. Do they still honor that?
