I bought a U-Bolt style bike lock (Abus) recently. Before I bought it I used my Google Fu to check how easy they are to pick, cut, break, etc. and hit the YouTube channel of lockpickinglawyer.
After watching a bunch of his videos, I am convinced that a simple lock picking set (bought or home-made) should be part of any bug out bag.
Funny. I have a set of shims I keep in my wallet. Was out a few weeks ago and a friend had one of those small first sentry/alert/whatever firebox "safe" things with some passports and documents she needed inside and lost the key.
Took me like 1 minute to open that lock. Those things are fairly easy but I was a bad ass and saved the day. lol
ITS tactical has the best lock pick sets I have found.
