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. Since Master and American on one now I would think all the higher end if not all padlocks would have serrated pins now. Except of course 0, 1 and 2 pins.
    I can't believe they put the code, i it is the code, on the bottom of the lock though

  2. I think I've got one of these. I'm pretty sure that my US Master is marked "DG"? I do know I've played with it, but I didn't pop it…

    I'll have a look around see if I can find it. 

  3. Who would of thought that Master Lock would have made a lock with 5 serrated pins. Nice picking, always a pleasure watching. (+1 : 8)
