Locks rarely have any extra markings to say they're part of a master system... occasionally there is a code stamped on the plug, but most of the time they don't have any markings. This is true though, more shear lines means a higher margin for error, so it can make picking easier. Not always, though.

It is possible to come across 2 locks which work wih the same key, since lots of different manufacturers use the same profiles, but the chances are still very slim. The chances of a key working in 2 of the same brand and model of lock are virtually zero.

I think the video guide said the bump key would need to be set to all 3's or something. Surely if you took your key for the master lock down to a key cutters and requested for them to cut a key which is set to all 3's they could do that and you could use it to bump the lock?.
Yes, you can take any old key and make a bump key from it. The cuts need to be set to the deepest cut, which is generally 9, but without a code machine you need to look at the lock itself to figure out the correct depth. You can't take a key to some random key cutting place because they don't use code machines; all they can do is duplicate existing keys for you. A locksmith won't cut any kind of bump key for you unless they know you personally and trust you.

Would bump keys work on newer low security locks?.
A basic bump key will open any standard pin tumbler lock providing it has the correct profile, depth and spacing.

That's probably because masters locks are very easy to pick and there is no need for them. And you're not honestly thinking of bumping that squire luggage lock, are you?

Certain buildings will have locks which are mastered in such a way that they can be opened by the emergency services in non-life threatening situations where busting the door down with an axe isn't necessary. These keys are more collectors items than anything else as tryout keys for various lever locks are available and do the same job.
