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. thanks for showing me what junk locks i have securing stuff on my utility truck be buying something different tomorrow

  2. That’s amazing. I wouldn’t think the momentum of the wafers would be enough to overcome the springs. I guess if the acceleration is enough it doesn’t matter how light the wafers are. I’m trying to picture just how this works: do one or two wafers get set on every hammer hit? Until they’re all set?

  3. Obviously an attempt to engineer a tough looking lock without much design work. They must be making money.

  4. Only $19.59 at Home Depot, what a bargain!
    They deserve more than a 3 minute bashing… is Bill getting soft? I heard he is going to work for Master next spring and will soon be beating up on Abus for providing quality locks at a reasonable price. That’s the rumor anyway 🙂

  5. I can’t believe after all the obvious flaws in Master Lock’s products that they wouldn’t hire a couple good engineers and make a solid locking mechanism by now? Maybe they’re confident selling so damn many cheap locks every year that they just don’t care about security. You’d think it would be a pride thing though wouldn’t you? Their locks are just a step above leaving the door wide open, I wouldn’t secure anything I care about with a ML.

    1. Bonzo the chimp, long time co-star with Ronald Reagan! Less than 1% of other chimpanzees can defeat a Master Lock, so it’s all good.

  6. Master Lock has got to 🗡LOVE🗡 you Mr.Bill. Yea right.🔫Brilliant video Can't get enough of master locks stupidity, And your ingenious methods of opening locks

  7. how is master lock not coming to you to make improvements to there product?
    after seeing many videos on how many of thier stuff is junk.. I get feeling they don't care if it works effectively or not

    1. Is that tiny notch at the very tip of the key the fifth wafer? I saw four as well at first and I could be wrong about that being #5
