Never dabbled, but I've SPPd, raked, zipped, jiggled, bypassed and bullied locks open.
Started back in the early 90s, got a bit more serious early 00s.
Check out the YouTube, Bosnian Bill and lock picking lawyer are good ones.
Couple of books/downloads out there.
Lockpicking overkill(I think that's the name) been a while since I read it) is a good one.
Lot of different kinds of picks out there, not all good, and it's not all about the tools, but still need some decent ones.
Most perishable skill I've found.
Way more than shooting or pool, it's crazy how fast you loose it, but it does come back quickly with practice.
Have fun, hit the flea market for old locks, keys are a pluss but not necessary.
