Definitely worth learning. Frankly, I have used just one pick profile to open almost everything I've run across that needed to be opened. I've opened the door locks on my truck (which was a pain in the ass compared to the house dead bolts). I've unlocked an old Master padlock at Mom's house that no one had a key to. And I took the locking gas cap off Granddad's truck after he passed away. Apparently no one knew where he kept the key to the gas cap. But it came off in less than a minute of probing the lock cylinder.
I have a set of individual picks, but I really like the "pocket knife" style fold out that
@jwtug posted above- separate tension wrench and it keeps all the picks together and in a case where they won't get broken.
The picks I have are apparently full hard 301 stainless or something similar- they'll snap if you bend them very much at all. They are not Southord though. And I've had zero training by a pro, so there's another problem.
