I'm still working on improving my skills with more basic locks, and I've picked up a Masterlock 140 for when I've improved to try out security pins.
Once I get past that stage, I'm considering the following:
Brinks shrouded padlock
Schlage deadbolt
American 1105 padlock
If anyone can provide some opinions on their order of difficulty, I would appreciate it. I know this is somewhat long term, but I'm trying to put together a roadmap for my progress. Also, if you have any other suggestions or think there should be another step between the 140 and these let me know too.
Thanks!
