  1. Wow I almost cant believe you wrote me back thank you so much and yeah ill definitely try the salvation army and the thrift stores and again thank you so much for taking the time to reply to me im a huge fan !!!! Thank you! !!

  2. hello Bosnianbill and everyone else im just starting to get into lock picking (about a month ) and making my own challenge locks Im looking for advice on where to get locks and pins ( reasonably inexpensive) make into challenge locks and how to find other people to trade off with but any advice will be greatly appreciated

  3. Hey Bill, could i send u a lock? Its a abus72/40 but it has a different keyway then the one u did a video on im pretty sure. Its driving me crazy i cant get past the warding to properly feel the pins. I am not able to send u a pm as i use my phone to watch YouTube.

  4. When that cylinder was stuck on you I just kept wanting to say – rap on the cylinder rap on the cylinder! Luckily you worked it open without having to do that.

  5. nice job bill.  I really need to start raking my locks more.  I could save alot of time trying to get into a false set.

  6. I was thinking that you all use tension tools to pick locks but is it work when you file key opening with little angle from top and bottom to make tensioning tool to pop out. Is it make things a little bit harder to pick or what?

  7. if you have a similar core around that is no filed you should put that in place and re-try the pick to demonstrate what the custom pins could have done with a proper core. i know he got the core with it already filed down so its a shame to not see what a challenge those pins could have been :/

  8. Novice picker here….is it fair to say that some pins will make various picking techniques easier? In this case it seems that filing the core made the bogatah (sp?) very successful.

  9. I must have been drunk when I stuck the tpin in upside down i thought I put it in the right way ha! But yes that's the way the core was when I got it but thanks for informing me that it makes it Easier to open like that and cool little trick with the raking I'll have to remember that trick

  10. That could be a VERY old cylinder from back in the days before standard pin kits. During that time locksmiths would file the plug to get pins to work as you stated Bill.
    We don't and shouldn't be filing plugs now days
    get a new plug and that will be a good lock again

  11. I think the sharp edges on those last two or the upside down drunken spool caught the threads and that was what was hanging it up. Looked like the threads had a bright, fresh scratch on them after you pulled it out.
