Most retail tools are guaranteed but your looking at this totally wrong. I use tools everyday for work being a millwright. I will admit I have a few off shore one offs for quick non intrusive work but to look at what you did and break that bar let's go one step further. The bar is warranted for replacement but what would you do if you were to hit your elbow when it broke and ended up breaking it. Off work for weeks, possibly medical bills etc etc. Save a few dollars to buy shit tools and possibly put yourself in harms way. I literally have thousands in snap-on and a Canadian brand called Grey and yes I have broken a few items but I can honestly say it was because I was using them for shit they weren't made to do. Just my $.02 worth
I pulled wrenches for the last 20 years before I retired. It would surprise you what people do with tools and hurt themselves, good tools and cheap tools.
