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. Hah.. "There are no screws in this one like I thought".. Afraid that all challenge locks will contain the patent pending "ScrewLock" technology now Bill? ;)

  2. Alien technology and squirrel toes lol I love the way you commentate your videos I laugh and learn. I have a question could you possibly do a video of a brinks 60mm commercial lock they sell them at walmart it is the model 662-60091 I just bought one and cannot even get a false set out of it serrated pins I believe it feels awful gritty way harder than anything I have tried so far. If you could do a video of you picking it with some tips I would be indebted to you forever. You are my favorite channel on youtube and the best I have seen at what you do.

  3. It's not the key to the cylinder if you pull the key out like a millimeter it will turn left key too long i got another one in the works! Bill you are free to do as you please with it if anyone wants it and I'll be sure to put more squirrel teeth in next time

  4. The reason the key did not turn smoothly was because there was one or more pins that were too short.  Measure the length if the pin and the depth of the cut on the key and you should have .500" .  If it is much less then try the length of the pin that will get you to .500" and it should work smooth.
