(973) Review: Sparrows Gridlock, Rockouts & Warlock

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. I am very pleased with these. I just got mine today. They are made well. As I have been getting better with pin tumbler locks, I am not sure about these. Just a few weeks ago a gal was locked out of her car and I could not help her. I hope to change that.

  2. u order there new crash bar bypass tool? i got one… would be cool to have a demo of that new bypass tool as well. looks like a cool set , sparrows sure is on the cutting edge of lock picking

  3. I suspect the car lock bypassing technique (top-of-the-doorway) I've seen on a certain repo channel is quicker. And probably much less money to get the tools (though they do take up more room to store).

    1. A lot of those call for prying the door quite a bit. I just think picking or rocking the lock is less intrusive and or damaging.
