Bear proofsome of those things are Sasquatch proof! The real good ones are the duel locks. The last time I worked out of a box was back in 2001 , so possibly there have been some changes!
Na all the bigger boxes still run the 2 recessed locks that you can barely get a key into. I used to solder a quarter to my tool box keys to make it easier to unlock them. I don't work the tools anymore either, but see lots of those kind of boxes on job sites. You could put a lot of guns the big chest type or even the bigger stand up ones. None are easy to break into. I have got into a few for various reasons, but it took a bit and I had access to all the tools a guy could want to do it. The tools in my brothers or my fitters box were worth some serious money. Lot of guys have several thousands of dollars worth of tools inside them
