People often ask what set to go for when starting out with Lock Picking.
I’d suggest going for the intro set if you’re just getting into it. It is a bit easier to use the individual picks and the choice of tension wrenches should help greatly.
The pocket set is excellent for portability or just throwing in a bag for use whenever its needed, but it doesn’t offer the same level of “feel” as the individual picks.
It is pretty fun hobby and can be a good thing to impress your mates.
