Non digital safe? Mechanical and/or keyed only?
I just had to break open my Sentry safe, purchased in 2016 from Costco. It did okay for a few years, but then started sticking. My ex wife tried to force the handle and something inside broke, so the handle didn't turn the mechanism to withdraw the bolts every time. I would generally he able to smack it with a rubber mallet and the bolts would withdraw, but yesterday, even that wasn't working. I ended up using a sawzall to cut off the hinge pin retainers, then a 6' steel breaker bar to pry it open. Took about 7 minutes.
Now I find myself in need of a safe. I am looking for something without a digital keypad or batteries, preferably with just a mechanical lock or even just keys. It needs to store a stack of paperwork, 6 to 10 master copies of my books, and eventually some small amount of metal bullion.
