So first, let me introduce myself. I'm a guy, aged 17, from The Netherlands who just started lockpicking. In the past couple of days I've only attempted locks without security pins, which was quite an easy task. But yesterday I found a Master No. 130 lying around. After a couple of tries I noticed it wasn't opening, and after some research on the internet I found out that it has security pins in it. Now, I have no idea on how to even attempt to pick this lock. Could someone please explain to me how to deal with these security pins. (After some research I found out that pins 3 and 4 are 'spools').
Thanks !
