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. the thing that i think makes this lock secure is all those tools that you need..if this was a lock out in the field, and you are only carrying a small essential set of picks, even if you had a flag pick i doubt youd have that modified rake, and that broken pick too.. id say that alone makes it a nice lock.

  2. Nicely-done, Bill.

    One thing that makes this lock a LOT easier is that the sliders are spring-biased. In the 3KS and another lock I'm working on, they're not, and so you really have to reset them by hand and deal with them falling down on counter-rotation.

    In your copious spare time, could you gut your lock and see how many actual differs there are on the sliders? Despite the shape of the key, mine only had two depths, as far as I could tell. That reduces the sidebar to 2^4=16 combos. 🙁
