  1. I enjoy your videos and wanted to get your opinion on something. Do you think the Sparrow "Tuxedo" set is a good set for someone who knows the basics and wants to expand his skills? If not what would you recommend? Thanks.

  2. Awesome Lock Bill. Very Cool. Keep up the great work. I hope you find Adrian he's like a missing Cat at the moment. LOL. Your end up going around the neighbourhood sticking up posters Adrian Missing please call if found. HA HA HA Nick.

  3. Unfortunately the custom pins made this lock easy to pick. I'm sure Bill can fix that though.
    The upside down 6th pin really helped by not allowing the driver to seat correctly.
    Pin-within a pin don't work well due to the size of the bible. There isn't enough room for them to work correctly.
    And remember "T" pins only work when there are no construction ball holes.

  4. I'm looking for a practice lock, not too challenging. I am what i would call an "advanced beginner". I can open pretty much any all standard pin lock, and i can deal with a few spools, haven't yet had success with serrated pins. If you have a lock that you think would be a good fit i would be very pleased to get it.

  5. I don't have a problem with you testing a lock before hand. I would much rather you be able to actually pick a lock and make videos. I remember that couple week stretch where you dealt with that lock with the bar in it and we had no new videos.

  6. Could it be that bosnianbill is in turn Buffalo Bill? Given the fact we have not seen or heard Adrian for many days. We all know Adrian can get out of any lock… so to keep him put he would need to be kept in a deep hole in the basement… Humm… 😉

    Love your videos bosnianbill! And please free ADRIAN!

  7. I don't know who Adrian is. I only heard his voice and you talk about him one time. But I probably don't know him anyways. He is probably just out at the bar again hanging out with the nice looking women. Lol

  8. Regarding this video, while looking at the key bitting does give you a bit of insight about the lock, I've never found seeing the key make a difficult lock any easier. I'll never see it as cheating. in my humble opinion.

  9. Excellent! I swear watching your videos equals improvement. Every night I line up a series of Americans, ABUS & assorted cylinders, put your videos on autoplay and work my way through the locks. I've seen a staggering increase in skill over the past couple months I've been doing this. Thanks for the non stop awesome uploads and tips.
