I went to A1 Safe in Plano to get some keys made and mentioned to the guy that I was looking for something harder to pick than the 130's and 140's I'd grown bored of. He was surprised that I intended to practice picking the lock and ended up giving me a huge masterlock No17 for free. He then told me he was in the process of making a key for it since the original had been lost and we started talking about how it's done. Well I got interested and asked him if I could buy a few blanks to try it myself and he ended up giving me 2 blanks for free as well.
What a nice guy huh? Now if I can just figure out how to impression it. I'll search around the forums for a bit and see what I can dig up.
