My vises are made by Panavise, a U.S. Company.  The one with the wide jaws is the model 350.  The smaller one is the model 301. Both have the 312 Base mount – www.panavise.com



  1. Bill, thanks for the thoughtful approach that you always come with.
    As a building official who is responsible for public safety I do have to voice a concern regarding your thumb turn suggestion.
    Keyed 2 side locks are prohibited in many instances because they can prevent egress in an emergency. Please advise the viewers to consult with their building and fire departments before investing in new hardware.

  2. I’ve seen a similar home made tool on youtube more than a year ago, the only difference is this tool is more professionally made.

  3. You act like this is a new Invention. Today I coincidentally saw a presentation from 2016 that had a tool just like this in it.

  4. Hey bill! This thing has existed for many years. When I first became a locksmith back in 2005 they were readily available in trade suppliers magazines, slight variations have come and gone but the principle has been around for a long long time.

    Kind of the same story with bumping, that was an old technique of locksmiths for years and years, nobody really batted an eye in the community about it because who cares, it worked for our needs. Then someone highlighted it on youtube and that was all she wrote for that.

    Great video,

  5. Yeah I was thinking to myself that these ain't exactly new, I've seen similar things being used since 2012. You can also find these on a load of chinese sites for near nothing, its kinda silly but then again, the tool its self is very simple and hugely effective at what its used for.

  6. I wonder if this tool could be recreated with one of those ratchet flex drives/Dremel flex drive and a custom end bit. Not a super complicated grabber there
