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. Great picking of Frustrating Faultless. The forth key pin was on a whim and not sure if it was working like I thought it would. The idea is that when it is picked, it would turn and the cuts would turn it into the shearline and bind up. I guess I'll have to get a cut away cylinder to test the theory.

  2. Glad at end we saw the key tag as the other locks sounded pretty cool with the name he gives them. But you never said the name on the one you picked in this video, but got to see it at end on the tag.

  3. Is it possible to use a 'challenge lock' as a regular lock?, as in: would you be able to install one into a door and use it as a high security lock?
